Direct Conversion of Pluripotent Human Embryonic Stem Cells into Functional Cell Therapy Derivatives Brings Cell-Based Regenerative Medicine to a Turning Point
San

publication of Dr. Parsons’ review article, titled “Constraining the
Pluripotent Fate of Human Embryonic Stem Cells for Tissue Engineering and Cell
Therapy – The Turning Point of Cell-Based Regenerative Medicine”, in British Biotechnology Journal at http://www.sciencedomain.org/issue.php?iid=243&id=11. In this review article, Dr. Parsons gives an
insight view on recent advances and breakthroughs in human embryonic stem cell
(hESC) research that have overcome some major obstacles in bringing hESC
therapy derivatives towards clinical applications, including establishing defined
culture systems for de novo derivation
and maintenance of clinical-grade pluripotent hESCs and lineage-specific differentiation of pluripotent hESCs by
small molecule induction. This technology breakthrough enables direct
conversion of pluripotent hESCs into a large supply of high purity neuronal
cells or heart muscle cells with adequate
capacity to regenerate CNS neurons and contractile heart muscles for
developing safe and effective stem cell therapies. Transforming pluripotent
hESCs into fate-restricted therapy derivatives
dramatically increases the clinical efficacy of graft-dependent repair
and safety of hESC-derived cellular products. Such milestone advances
and medical innovations in hESC research allow generation of a large supply of clinical-grade
hESC therapy derivatives targeting for major health problems, bringing cell-based
regenerative medicine to a turning point.
Human stem cell therapy derivatives are
extremely attractive for therapeutic development because they have direct
pharmacologic utility in clinical applications, unlike any cells originated
from animals and other lower organisms that are only useful as research
materials. The human stem cell is emerging as a new type of pharmacologic agent
of cellular entity in cell-based regenerative medicine, because human stem cell
therapy derivatives have the potential for human tissue and function
restoration that the conventional drug of molecular entity lacks. The ability
of a human stem cell, by definition, to both self-renew and differentiation
makes it a practically inexhaustible source of replacement cells for many
devastating or fatal diseases that have been considered as incurable, such as
neurodegenerative diseases and heart diseases. The pharmacologic activity of
human stem cell therapy derivatives is measured by their extraordinary cellular
ability to regenerate the tissue or organ that has been damaged or lost. In
this regard, the pharmacologic utility of human stem cells cannot be satisfied only
by their chaperone activity, if any, to produce trophic or protective molecules
to rescue existing endogenous host cells that can simply be achieved by a small
molecule or a drug of molecular entity. There is a large unmet healthcare need
to develop human embryonic stem cell (hESC)-based stem cell therapies to
provide optimal regeneration and reconstruction treatment options to restore
normal tissues and function. Clinical
applications of hESC therapy derivatives provide the right alternative
for many incurable diseases and major health problems that the conventional mode of drugs and treatments cannot.
We must bear in mind that the pluripotent
hESC itself cannot be used for therapeutic applications. It has been recognized that pluripotent hESCs must
be transformed into fate-restricted derivatives before use for cell therapy. Conventional
approaches rely on multi-lineage inclination of pluripotent cells through
spontaneous germ layer differentiation, which yields embryoid body (EB)
consisting of a mixed population of cell types that may reside in three
embryonic germ layers and results in inefficient, incomplete, and
uncontrollable differentiation that is often followed by phenotypic
heterogeneity and instability, hence, a high risk of tumorigenicity. Growing
evidences indicate that incomplete lineage specification of pluripotent cells via
multi-lineage differentiation often resulted in poor performance of such stem
cell derivatives and/or tissue-engineering constructs following transplantation.
In addition, most currently available hESC lines were derived and maintained on
animal feeder cells and proteins, therefore, such hESCs have been contaminated
with animal biologics and unsuitable for clinical application. Without a
practical strategy to convert pluripotent cells direct into a specific lineage,
previous studies and profiling of hESC differentiating multi-lineage aggregates
have compromised their implications to molecular controls in human embryonic
development.
Recent advances and technology breakthroughs
in hESC research have overcome some major obstacles in bringing hESC therapy
derivatives towards clinical applications, including establishing defined
culture systems for de novo derivation of clinically-suitable stable
hESC lines from human blastocysts that have never been contaminated by animal
cells and proteins, and direct conversion of such pluripotent hESCs into a
large supply of clinical-grade functional human neuronal or cardiomyocyte
therapy derivatives to be translated to patients for CNS or heart repair. Without
an understanding of the essential developmental components for sustaining hESC
pluripotence and self-renewal, hESC lines are at risk for becoming unhealthy
and unstable after prolonged culturing under animal feeders, feeder-conditioned
media, or artificially-formulated chemically-defined conditions. Resolving
minimal essential requirements for sustaining embryonic pluripotence allows all poorly-characterized and unspecified biological
additives, components, and substrates in the culture system, including those
derived from animals, to be removed, substituted, or optimized with defined
human alternatives for de novo derivation and long-term maintenance of GMP-quality xeno-free stable hESC
lines and their human therapy derivatives. Formulation of minimal
essential defined conditions renders pluripotent hESCs be directly and
uniformly converted into a specific neural or cardiac lineage by small signal
molecule induction. Such milestone advances and medical innovations in hESC research
enable generation of a large supply of high purity clinical-grade hESC neuronal
and heart muscle cell therapy products as powerful cellular medicines that can
offer pharmacologic utility and capacity for CNS and heart regeneration that no
conventional drug of molecular entity can. Currently,
these hESC neuronal and cardiomyocyte therapy derivatives are the only
available human cell sources with adequate capacity to regenerate neurons and
contractile heart muscles, vital for CNS and heart repair in the clinical setting.
The availability of human neuronal and cardiomyocyte therapy derivatives in
high purity and large quantity with adequate potential for CNS and myocardium
regeneration will facilitate CNS and myocardial tissue-engineering and
accelerate the development of safe and effective cell-based therapy to resolve these
major health problems. Further improving policy making and funding situation for hESC research
would open up a new dimension of cell therapy-based future medicine to provide new medical treatments for many devastating
and life-threatening diseases and injuries. Transforming pluripotent hESCs into
fate-restricted therapy derivatives dramatically
increases the clinical efficacy of graft-dependent repair and safety of
hESC-derived cellular products, bringing cell-based regenerative medicine to a
turning point. Please read Dr. Parsons’ full open access article at http://www.sciencedomain.org/issue.php?iid=243&id=11.

Embedding Lineage-Specific Developmental Programs into the Open Epigenomic Landscape of Pluripotent Human Embryonic Stem Cells Offers Efficiency in Deriving Cell Therapy Products for the Future of Regenerative Medicine
San
Diego Regenerative Medicine Institute
and Xcelthera announce the
publication of Dr. Parsons’ review article, titled “Embedding the Future of
Regenerative Medicine into the Open Epigenomic
Landscape of Pluripotent Human Embryonic Stem Cells”, in Annual Review &
Research in Biology at http://www.sciencedomain.org/issue.php?iid=239&id=9. In this review article, Dr. Parsons gives
an insight view on the human stem cell epigenomes in discerning the intrinsic
plasticity and regenerative potential of human stem cell derivatives from various
sources as well as recent advances on uncovering the developmental programs
embedded in neural and cardiac lineage-specific differentiation of pluripotent
human embryonic stem cells (hESCs) that lead to efficiency in deriving neural
and cardiac elements for cell-based therapies.
Human stem cells are extremely attractive
for therapeutic development because they have direct pharmacologic utility in
clinical applications, unlike any cells originated from animals and other lower
organisms that are only useful as research materials. The human stem cell is emerging
as a new type of drug of cellular entity that can offer pharmacological utility
and capacity for human tissue and function restoration that the conventional
compound drug of molecular entity lacks. However, to date, the lack of a
clinically-suitable source of engraftable human stem/progenitor cells with
adequate neurogenic potential has been the major setback in developing safe and
effective cell-based therapies for regenerating the damaged or lost central nervous system (CNS) structure and
circuitry in a wide range of neurological disorders. Similarly, the lack of a
clinically-suitable human cardiomyocyte source with adequate myocardium
regenerative potential has been the major setback in regenerating the damaged
human heart. Pluripotent hESCs, derived from the pluripotent inner cell mass or
epiblast of the human blastocyst, have both the unconstrained capacity for long-term
stable undifferentiated growth in culture and the intrinsic potential for differentiation
into all somatic cell types in the human body, holding tremendous potential
for restoring human tissue and organ function. Given the limited capacity of
the CNS and heart for self-repair, transplantation of hESC neuronal and heart
cell therapy derivatives holds
enormous potential in cell replacement
therapy for neurodegenerative and heart diseases that cost the healthcare
system > $500 billions annually. There
is a large unmet healthcare need to develop hESC-based therapeutic solutions to
provide optimal regeneration and reconstruction treatment options for normal
tissue and function restoration in many major health problems. However,
realizing the developmental and therapeutic potential of hESC derivatives has
been hindered by conventional approaches for generating functional cells from
pluripotent cells through uncontrollable, incomplete, and inefficient
multi-lineage differentiation. Growing evidences indicate that incomplete
lineage specification of pluripotent cells via multi-lineage differentiation
often resulted in poor performance of such stem cell derivatives and
tissue-engineering constructs following transplantation. The development of
better differentiation strategies that permit to channel the wide differentiation
potential of pluripotent hESCs efficiently and predictably to desired
phenotypes is vital for realizing the therapeutic potential of pluripotent
hESCs.
The eukaryotic genome is packaged into
chromatin, a nucleoprotein complex in which the DNA helix is wrapped around an
octamer of core histone proteins to form a nucleosomal DNA structure, known as
nucleosome, that is further folded into higher-order chromatin structures with
the involvement of other chromosomal proteins. Chromatin modifications, such as
DNA methylation and histone modifications, serve as important epigenetic marks
for active and inactive chromatin states, thus the principal epigenetic mechanism
in early embryogenesis. Discerning the intrinsic plasticity and regenerative
potential of human stem cell populations reside in chromatin modifications that
shape the respective epigenomes of their derivation routes. The broad potential
of pluripotent hESCs is defined by an epigenome constituted of open
conformation of chromatin. The hESCs are not only pluripotent, but also
incredibly stable and positive, as evident by that only the positive active
chromatin remodeling factors, but not the negative repressive chromatin
remodeling factors, can be found in the pluripotent epigenome of hESCs. The
normality and positivity of hESC open epigenome also differentiate pluripotent
hESCs from any other stem cells, such as the induced pluripotent stem
cells (iPS cells) reprogrammed from adult cells with known oncogenes and the
tissue-resident stem cells. Somatic cell nuclear transfer and
transcription-factor-based reprogramming have been used to revert adult cells
to an embryonic-like state with extremely low efficiencies. Although pluripotent,
the iPS cells and ESC derived from cloned embryos by somatic nuclear transfer are
made from adult cells, therefore, adult cell-originated pluripotent cells carry
many negative repressive chromatin remodeling factors and unerasable genetic
imprints of adult cells that pluripotent hESCs do not have. Somatic
cell nuclear transfer and factor-based reprogramming are incapable of restoring
a correct epigenetic pattern of pluripotent hESCs, which accounts for abnormal
gene expression, accelerated senescence, not graftable, and immune-rejection
following transplantation of reprogrammed cells. These major drawbacks have
severely impaired the utility of reprogrammed or deprogrammed or direct or
trans-differentiated somatic cells as viable therapeutic approaches.
Using hESCs to develop cellular medicine for the brain and the heart must first transform pluripotent hESCs into CNS or heart fate-restricted cell therapy derivatives. Recent advances and breakthroughs in hESC research have overcome some major obstacles in bringing hESC therapy derivatives towards clinical applications, including establishing defined culture systems for de novo derivation and maintenance of clinical-grade pluripotent hESCs and lineage-specific differentiation of pluripotent hESCs by small molecule induction. This technology breakthrough enables high efficient direct conversion of pluripotent hESCs into a large supply of high purity neuronal cells or heart muscle cells with adequate pharmacologic capacity to regenerate CNS neurons and contractile heart muscles for developing safe and effective stem cell therapies. Transforming pluripotent hESCs into fate-restricted therapy derivatives dramatically increases the clinical efficacy of graft-dependent repair and safety of hESC-derived cellular products. Currently, these hESC neuronal and cardiomyocyte therapy derivatives are the only available human cell sources with adequate pharmacologic capacity to regenerate neurons and contractile heart muscles that no conventional drug of molecular entity or tissue-derived stem cells can. Embedding lineage-specific genetic and epigenetic programs into the open epigenomic landscape of pluripotent hESCs offers a new dimension for direct control and modulation of hESC pluripotent fate when deriving clinically-relevant lineages for regenerative therapies.

CIRM Employs Negative Reviewers of No Scientific Integrity to Make Dishonest Comments and Scores to Block Prop71 Stem Cell Research for Funding and Cover Up COI
To understand why billions
of Prop71 have flowed into conflicts of interest (COI) but not stem cell
research from CIRM unobscurely, it
may help to look into CIRM flawed
review process, particularly the part that has been forbidden by CIRM internal COI to disclose to the public, covered
up as CIRM pre-application or LOI. It
is interesting to see CIRM president
Alan Trounson’ very public demand for his $70 million alpha clinic proposal
while, unseen by the public, he is so evidently negligent or even negative
about stem cell research and therapy in handling CIRM
flawed grant review process as CIRM
president. The only problem is that, so far, CIRM
has not had one FDA-approved stem cell therapy, not even any CIRM sponsored IND or clinical trials. Without
clinically-suitable human stem cells or FDA-approved stem cell therapy, Alan
Trounson’s alpha clinics would be no different from those stem cell con man’s
clinics hunted by FBI. It would turn out to be just another way for Alan
Trounson to get $70 million freebies for CIRM
COI, while under the cover he has been deliberately blocking those real
beneficial proposals that would provide stem cell therapy for his alpha clinics
using CIRM COI flawed review process
with his apparent consent.
If ICOC’s COI is only
speculation in public, COI in CIRM
grant review is monopoly, even to the extent of extortion. Therefore, it is no
surprise CIRM has been very resistant
to be transparent in its grant review. So far, it seems that CIRM reviewers have been only capable of making
negative comments that are so full of false statement, factual error, bias or
predisposition, COI that have comprised the integrity and credibility of any
advices provided by the reviewers. It is quite shocking that CIRM reviewers of no scientific integrity usually could not note any strength of hESC research proposal and intentionally gave false or biased or dishonest comments
and scores against scientific evidences that did not reflect the overall impact and scientific merit of
hESC grant applications (see hESC grant title and summary below for example). Our
proposal shown below is to understand molecular mechanism in human embryonic
stem cell neuronal differentiation using novel lineage-specific differentiation
technique in hESC research breakthrough. Such technique has never been
described before us. Only RA effect on hESC differentiating multi-lineage
embryoid body has been described before, but the effects are small, and
molecular mechanism in human and mouse ESC is totally different. There is
nothing in our proposal about iPS cells and some other irrelevant comments made
by CIRM reviewers. We have written
to CIRM president/vice president, CIRM , ICOC multiple times about such flawed reviews
from CIRM reviewers before, however,
it seems that CIRM president/vice
president or chair or ICOC have never been able to address such serious issues
as CIRM reviewers’ COI or scientific
misconduct, deliberately brushed it off, never responded to our complaints
about CIRM flawed reviews or COI in CIRM review, and covered it up by consent to
reviewers’ COI or false statement or flawed review. Considering many of CIRM ICOC members are leaders, physicians, Deans,
and Presidents who know more than anyone else how serious a issue of scientific
misconduct is in their own institutions, particularly provided by CIRM review comments for unmistakenable evidences,
it would be detrimental for us to think that CIRM
or ICOC or CIRM president/vice
president or chair have been actually behind CIRM
reviewers’ COI, false statement, or scientific misconduct by deliberately avoiding
to address CIRM flawed grant review
process.

Molecular Controls in Human
Embryonic Stem Cell (hESC) Neuronal Lineage Specification
The hESCs provide a powerful in vitro
model system to investigate molecular controls in human embryonic neurogenesis
as well as an unlimited source to generate the diversity of human neuronal cell
types for CNS repair. However, realizing the potential of hESC derivatives has
been hindered by conventional approaches for generating neuronal cells from
pluripotent cells through uncontrollable,
incomplete, and inefficient multi-lineage differentiation. We found that pluripotent hESCs maintained
under the defined culture conditions can be uniformly converted into a specific
neuronal or cardiac lineage by small molecule induction. This technology
breakthrough enables well-controlled efficient neuronal lineage-specific
differentiation direct from the pluripotent state of hESCs. In this project,
this novel hESC model of neuronal lineage-specific progression will be
characterized and used for genome-wide genetic and epigenetic profiling to
generate a comprehensive knowledge of
developmental regulators and networks for identification of molecular controls
in hESC neuronal lineage specification. Fulfilling the goal of this project
will be provide a comprehensive understanding of molecular neurogenesis in
human embryonic development, thereby, reveal potential molecular and cellular therapeutic targets for the prevention and
treatment of CNS disorders. The outcome of
this project will have a transformative impact on a broad area of
biomedical sciences and public health.

Thank you for
submitting your proposal under the CIRM
RFA 13-02: Basic Biology V Awards. After careful consideration, your PreApp was
not selected for further review under this RFA.
The goal of the
PreApp process is to identify proposals that are the most responsive to the RFA
objectives and likely to be competitive. For this competition we received over
340 PreApps and selected about 60 for a full application. The process was
designed to handle a large volume of proposals and to ensure a rapid
turn-around on the review. Reviewers may provide brief comments that highlight
strengths and weaknesses where appropriate. The comments are not comprehensive
and do not necessarily provide all the reasons for an invitation or denial.
Each application is assigned to 3 independent reviewers and each reviewer
assesses approximately 20-30 PreApps within their area of expertise and scores
the applications on a scale of 1 to 100, 100 being the most meritorious. CIRM scientific staff further assesses proposals to
ensure that projects meet eligibility requirements and are responsive to the
RFA. CIRM invites the most highly
ranked and responsive PreApps as determined by the external scientific
reviewers and CIRM science officers.

SUMMARY OF REVIEW
Overall Scientific Score: 33.33
Comments provided by reviewers:
Comments 1:
Strengths:
The
use of an in-vivo assay in Milestone 3 is very significant as it validates the in-vitro
results of all the other Milestones.
Weaknesses:
The
direct conversion of hESCs to neuronal derivatives has already been extensively
described by many different laboratories. (our
response: the reviewer’s statement is false & against scientific evidences.
The fact is the direct conversion of hESCs from the pluripotent state to
neuronal derivatives has never been done by any laboratories before us.)
It has
been shown that inhibition of the TGFB pathway by SB and LDN small compound is
sufficient to robustly induce conversion to telencephalic. (our response: The reviewer did not provide
the fact that it was induced from neuroepithelial cells isolated from embryoid bodies (EBs) in extremely low
efficiency by University of Connecticut
& groups connected to CIRM vice
president/UC connect/Sanford/UC. Our study overcomes their shortcoming to
generate neurons direct from hESCs in high efficiency and purity, not isolated from
EB. The fact the reviewer did not
disclose shows that this review had conflicts of interest (COI) and intentionally
gave false or biased or dishonest comments against scientific evidences, which has affected the integrity of advice provided
by this reviewer).
The
use of RA is sub-optimum as it as it generates random sets of neurons, which
will make collective data analysis useless. (Our response: the reviewer’s statement is false & against
scientific evidences. RA is optimized to induce neuroectoderm and neuronal differentiation
from hESCs to a large supply of neuronal cell type and subtypes, which is
critical for collecting data for analysis of molecular mechanism in hESC
neuronal lineage specification.)
Comments 2: (our response: our
proposal is to investigate molecular mechanism in hESC neuronal lineage-specific
differentiation and has nothing to do with iPS cells and the negative comments
of this reviewer (see title & summary). The reviewers’ comments are false,
which show COI since this review could not note any strength of this hESC
proposal and intentionally gave false
or biased or dishonest comments against scientific evidences, and which has affected the integrity of advice provided
by this reviewer).
Weaknesses:
- This protocol for differentiating human iPSCs into neurons has not
particular advantages respect to others already present in the literature,
while having some substantial drawbacks:
1) this protocol is not designed to generate one particular neuronal
subtype while generating a variety of very different neurons. It is not clear
which relation is existing between DA and spinal cord neurons which are both
generated by this same protocol.
2) it is not explained which particular type of DA or spinal cord neurons
are generated with this protocol. Are DA neurons patterned as ventral
mesencephalic Pitx3+ neurons? This is a crucial information for generating
therapeutic relevant neurons.
3) Retinoic Acid (RA) it is a well-known inducer of caudal neuronal
subtypes. It is therefore unclear how
DA neurons can be specified in this
particular regimen
4) Preliminary data are missing showing electrophysiological maturation
and activity of iPSC-derived neurons
Considering these pitfalls, caution is required in employing this
protocol in large extent and a better characterization of the differentiated
neurons is necessary to validate the system.
Comments 3: (our response: our
proposal is to investigate molecular mechanism in hESC neuronal lineage-specific
differentiation using a novel technology by small signal molecule induction. The
reviewer’s comments are vague, did not give any specifics. It is commonly known
that miRNAs are governors of regulatory circuits. The reviewers’ comments are
biased, which show COI since this review could not note any strength and apparent
novelty of this hESC proposal and intentionally gave false
or biased or dishonest comments against scientific evidences, and which has affected the integrity of advice provided
by this reviewer).
novelty of this application not at all clear
many vague, sweeping statements about the transformative nature of the
work, but very little focus
not at all clear how regulatory circuits will emerge from miRNA profiling

Skating on Thin Ice --- The Bottled-Up Stem Cell Community Deceived by Dictating Interest and High Impact of Unquestionable Prestige
Today, with the world second largest
economy and a new generation emerging from the 90th, China ’s culture
revolution has been left behind in a bottled-up history. No one, not even those
who were born into it, could make sense of culture revolution any more, could
make sense of the insanity, brutality, and mass destruction committed by those
who were so young so innocent. Only those who once lived in the bottle and had
their life dictated by the unquestionable will and sugar-coated political
interest of a single high power beyond their control could believe what had
really happened was totally unavoidable. For the rest, reading culture
revolution is like reading the consequence of irrationality. In my teenage
years, not even through my aunt’s hilarious imitation, I could make sense that
my young, handsome, intelligent, and kind parents, uncles and aunts, would
leave their infant kids alone at home in the dark, voluntarily go to do their
totally ridiculous duty dancing on the streets just to show their devotion to a
dying old man. Until they finally got their own common sense back, just in time
to catch the last nearby train flee out of the exploded conflict zone, leaving
their toddlers behind to survive a war-torn city.
The recent wave of induced pluripotent
stem cells (iPS cells) in the stem cell community is just as insane as the
culture revolution, making no sense at all to anyone who has little bit of
common sense, to anyone who has little bit of scientific integrity. Besides the
Nobel committee’s golden framed words that need Karolinska Institute’s
intelligence to understand, besides the perplexed news persons’ copied words
that do not need Karolinska Institute’s intelligence to tell that it sounded
very much like a scam, what has Yamanaka really accomplished? Yamanaka put not
just one, not two, not three, but 4 oncogenes into skin cells, not even the
skin of humans but lab rats, rationally or scientifically, he would not get
anything coming out of it but cancer cells. If Yamanaka told the public in lay
language what he really did, probably any ordinarily people would only think he
was just some mad scientist. However, it was told through the high impact
peer-reviewed prestigious scientific journal Cell, it was told in sugar-coated
political interest by highly-trusted big names as the “safe” and “ethical”
alternate for human embryonic stem cells (hESCs), it was copied by every major
news agencies throughout the world as “the biggest breakthrough of stem cell
research” without hearing a single critique or even precaution, like a man-made
earthquake with the magnitude that could even shake the more than 100 years of
unquestionable prestige of Nobel Assembly. Although Yamanaka’s Bernie Madoff scam
in the stem cell community does not make any sense scientifically, it does make
sense monetarily if simply check how much taxpayer money has gone into the epicenter
of Yamanaka iPS cells from NIH and CIRM since.
In 1989, James was inLondon , stayed in Margaret
Thatcher’s old flat. He visited Berlin
Wall without any speculation that someday it would come down. He had to
memorize his passport number in case that the Berlin Wall might really prevent
him from coming back to the free world. Then, a few months later, it was gone,
forever. Danny was in Beijing ,
turned on the TV in his hotel room and saw CNN to his surprise. He thought
Chinese people could actually watch CNN, how wonderful. I was in the same city,
and like all the Chinese people only 100 feet away from his Westerner-only
hotel, did not even know the existence of CNN and could only watch one single state-controlled
news broadcast – China Central News. Nearly 20 years later, when I sit in front
of my parents’ TV bigger than the one we had, that was still all I could watch.
If talking enforced high impact, the Central News broadcast occupies the prime
time, copying the same exact words with never-changed sugar-coated tone through
every channel, every household, every neighborhood, and every dinner table of
an entire country that I have never missed even a bit. A KFC and a large
shopping mall erupted right next to my old elementary school that was still
very much unchanged. I went into KFC to taste the chicken that looked and
tasted just like a KFC, then went into the shopping mall to spend my parents’
money and brought a few pairs of pure gold earrings, then went by my old elementary
school that looked just like what I remembered, having this incredible feeling
that I was going through a time machine. Hong Kong ,
from where I flew in, was only 2 hours away. Their TV satellites could pick up
the signals of some Hong Kong channels.
However, the interfering signals to those channels were so bad, few minutes
staying on those snowy channels would only make the Central News sound
unbelievably wonderful.
Although Berlin Wall had come down, without transparency, the peer-review system can be easily broken by the dictating interest and high impact of unquestionable prestige, and Berlin Wall can always be rebuilt by a privileged few to implement their own will and fence away fair competition and everything else that a democratic free country has stood for.
This piece is written in memory of Margaret Thatcher, the only woman and only scientist who had become a great politician of the world and had sailed through a stormy era in our time.

NIH Response to Letter to NIH Director Francis Collins
Dear Dr. Gadbois,
Thank you for your response on behalf of
Dr. Francis Collins. Although we do not have NIH actual award# for human
embryonic stem cell (hESC) research, according to NIH online statistics at http://stemcells.nih.gov/research/funding/pages/Funding.aspx,
in 2012, only 10% of total NIH fund to stem cell research (~ $1.468 billion)
was gone into hESC research, while 56% (~ $822 million) was gone into
non-human stem cells. The significance and benefit of hESC research should be
in reverse with the fund supported by NIH. In the 10%, hESC research is often
only a tiny fraction or small project of adult induced pluripotent stem (iPS)
cell U grants or large center grant awards, so the actual NIH fund to hESC
research is even much less than the 10%.
My hESC grant applications have

Title: Preclinical study of a novel
neuronal progenitor induced from human embryonic stem cells in spinal muscular
atrophy model, in
response to NIH funding opportunity Program Announcement (PAR) Number: PAR-11-038 Title: Preclinical
Research on Model Organisms to Predict Treatment Outcomes for Disorders
Associated with Intellectual and Developmental Disabilities (R01).
Project
summary: Spinal muscular
atrophy (SMA) is a devastating, untreatable, and one of the most common genetic
neurodevelopmental diseases leading to infant mortality. Human stem cell transplantation
represents a promising therapeutic approach closest
to provide a cure to restore the lost nerve tissue and function for SMA.
However, to date, lacking of a clinically-suitable source of engraftable human
stem/progenitor cells with adequate neurogenic potential has been the major
setback in developing effective cell-based therapies. In spite of proffering
cures, realizing the developmental and therapeutic potential of
pluripotent human embryonic stem cells (hESCs) has been hindered by the
inefficiency and instability of generating desired cell types from pluripotent
cells through multi-lineage differentiation. To
achieve uniformly conversion of pluripotent hESCs to
a neuronal lineage, I have established a small molecule induction approach to
generate a large supply of novel nurr1-positive human neuronal
progenitors direct from the pluripotent state
of hESCs (hESC-I hNuPs) in high efficiency, purity, and neuronal
lineage specificity to support preclinical research. SMA, characterized by
selective degeneration of spinal cord motor neurons, provides an ideal model
for in vivo motor neuron dysfunction bioassay.
In this project, hESC-I hNuPs will be
transplanted into animal models of SMA to
determine if the engrafted cells will extend life-span and improve the motor
function by differentiation into motor neurons for nerve regeneration and
reinnervation of host muscle to provide preclinical evidences of efficacy and safety
against incurable motor neuron disease. Their
therapeutic behavior, including engraftment/cell survival/integration,
migration, differentiation into motor neurons, graft-dependent
nerve regeneration and reinnervation of host muscle, and motor function
recovery will be assessed for evidences of efficacy, and a lack of tumors
and inappropriate cell type formation will be assessed for evidences of
safety. Assessment of the potential of hESC-I hNuPs
in disease models of SMA will offer critical insights into novel therapeutic
strategies against incurable motor neuron disease as well as provide necessary
and sufficient preclinical evidences of safety and efficacy to demonstrate
their potential as stem cell therapy to be translated to SMA patients
for motor neuron repair in clinical trials. The
outcome of this proposal will have significant impact on the advance of
medicine to provide treatment options for incurable motor neuron
diseases in pediatric patient
populations.

Title: Dopaminergic specification of
human embryonic stem cells for cell-based therapy against Parkinson’s disease (Phase I), in response to NIH
funding opportunity Program
Announcement (PA) Number: PA-10-122 Title: SHIFT Award: Small Businesses Helping Investigators
to Fuel the Translation of Scientific Discoveries [SBIR: R43/R44].
Project
summary: To
date, lacking of a large supply of clinical-grade human stem/progenitor cells
with adequate neurogenic potential has been the major setback in developing
effective cell-based therapies for restoring the damaged CNS. Pluripotent human embryonic stem cells
(hESCs) proffer cures for a wide range of
neurological disorders by supplying the diversity of human neuronal cell
types in the developing CNS for repair. However, realizing the therapeutic
potential of hESCs has been hindered by the current state of the art for
generating neuronal cells from pluripotent cells through
multi-lineage differentiation, which is
uncontrollable, inefficient, instable, highly variable, difficult to reproduce
and scale-up. We found that pluripotent
hESCs maintained under the defined culture
conditions can be uniformly converted into a specific lineage by small molecule induction. The goal of this project is to use a novel small molecule induction approach for well-controlled
efficiently directing neuronal lineage-specific differentiation of hESCs from
the pluripotent stage towards human neuronal progenitors and neurons at scale,
purity, and DA regenerative potential suitable for preclinical development of
cell-based therapy against Parkinson’s disease (PD), a prototypical age-related neurodegenerative disorder. Retinoic
acid (RA) was found to induce the specification of neuroectoderm direct from the pluripotent state of hESCs and trigger
progression to neuronal progenitors and neurons efficiently by promoting nuclear translocation of Nurr1. In the
phase I of this project, the cascade of hESC neuronal
lineage-specific differentiation by small molecule induction will be
characterized. These characterizations will be used to optimize the hESC neuronal differentiation protocol and
to define their homogeneity and dopaminergic (DA) potential. These studies in Phase I will be used to
establish the feasibility of this approach prior to initiating Phase II for large-scale molecular profiling to define stage-specific
human embryonic neurogenic factors and for preclinical studies of their
therapeutic effect in vivo in the DA dysfunction models. These studies will lead
to producing a large supply of well-characterized human neuronal progenitors
and neurons in high purity and adequate DA regenerative potential for
therapeutic applications. Further assessment of their potential in the PD
models will offer critical insights into novel neuron replacement therapy as
well as provide necessary and sufficient preclinical evidences of safety and
efficacy for predicting stem cell therapy outcomes in clinical trials
against PD. The outcome of this proposal will have
significant impact on the advance of medicine to provide novel graft-dependent
stem cell therapy for restoring the lost tissue and function in CNS disorders.

Title: Cardiomyocyte specification of
human embryonic stem cells (hESCs) for cell-based therapy for myocardium
regeneration (Phase I), in response to NIH funding opportunity Program Announcement (PA) Number: PA-09-249 Title: Directed Stem Cell Differentiation for Cell-Based
Therapies for Heart, Lung, and Blood Diseases (SBIR),
Project summary: To date, lacking of a suitable human cardiomyocyte source with
adequate myocardium regenerative potential has been the major setback in
regenerating the damaged human heart. Pluripotent
human embryonic stem cells (hESCs) proffer unique revenue to generate a large
supply of cardiac lineage-committed cells as human myocardial grafts for
cell-based therapy. Due to the prevalence of heart disease worldwide and acute
shortage of donor organs or adequate human myocardial grafts, there is intense interest in developing hESC-based therapy
for heart disease and failure. However, realizing the therapeutic
potential of hESCs has been hindered by the current state of the art for
generating cardiomyocytes from pluripotent cells through
multi-lineage differentiation, which is
uncontrollable, inefficient, instable, highly variable, difficult to reproduce
and scale-up. We found that pluripotent
hESCs maintained under the defined culture
conditions can be uniformly converted into a specific lineage by small molecule induction. The goal of this project is to use a novel small molecule induction approach for well-controlled
efficiently directing cardiac lineage-specific differentiation of pluripotent
hESCs towards human cardiac precursors and cardiomyocytes at scale, purity, and
myocardium regenerative potential adequate for preclinical development
of cell-based therapy for heart disease.
Nicotinamide was found to induce the specification of cardiomesoderm direct from the pluripotent state of hESCs and
trigger progression to cardiac precursors and cardiomyocytes efficiently. The cascade of hESC
cardiac lineage specific differentiation by small molecule induction will be
characterized. These characterizations will be used to identify cardiac
stage-specific markers and optimize hESC cardiac lineage-specific
differentiation by small molecule induction to beating cardiomyocytes. These
studies in Phase I will be used to establish the feasibility of this approach
prior to initiating Phase II for large-scale molecular profiling and for preclinical studies of their therapeutic effect in myocardium
regeneration in vivo. These studies will lead to producing a large supply of well-characterized
human cardiac precursors and cardiomyocytes in high purity and adequate
myocardium regenerative potential for commercial and therapeutic applications. This
project is crucial to driving the advance of medicine to provide optimal treatment options for the damaged or diseased
hearts that have been lacking. The outcome of this project will have a
transformative impact on a broad area of biomedical sciences and public health.

Dear Dr. Parsons,
Your recent email dated
April 17, to Dr. Francis Collins, Director of the National Institutes of Health
(NIH), regarding stem cell research funding, was referred to me for reply. I
appreciate the opportunity to respond to your email.
Across NIH,
stem cell research is a high priority. As you know, NIH funds a range of stem
cell research, using human and non-human adult stem cells, embryonic stem
cells, and induced pluripotent stem cells. NIH-funded research is exploring
potential applications in regenerative medicine, drug screening, and the study
of the molecular pathways in biological development and human disease. There is
no budget set for stem cell research overall or in specific categories; the
individual institutes and centers at NIH make their decisions on awarding
grants and contracts based on considerations of scientific merit and relevance
to their mission, programs, and priorities.
You state
that NIH has cut funding for research with human embryonic stem cells under the
current administration. That is not correct--NIH has actually increased support
by $58.4 million between fiscal year 2008 ($88.1 million awarded) and fiscal
year 2012 ($146.5 million awarded). You can find additional details about NIH
stem cell research funding at http://stemcells.nih.gov/research/funding/pages/Funding.aspx.
You may also
be interested in reading the NIH Guidelines for Human Stem Cell Research
(Guidelines), posted at http://stemcells.nih.gov/policy/pages/2009guidelines.aspx.
NIH has approved 209 human embryonic stem cell lines
for use in NIH-funded research under the Guidelines. Information on these lines
is available at http://grants.nih.gov/stem_cells/registry/current.htm. If you have human embryonic stem cell lines that
you think meet the requirements of the Guidelines, I encourage you
to submit your documentation for consideration by NIH.
Finally, it is of utmost
importance to NIH to conduct high quality peer review. NIH has established a
peer review appeal system (see NOT-OD-11-064) to provide
investigators and applicant organizations the opportunity to seek
reconsideration of the initial review results if, after consideration of the
summary statement, they believe the review process was flawed as outlined
below. Additional details of this appeals process can be found at http://grants.nih.gov/grants/peer_review_process.htm#Appeals.
Thank you again for your
interest in stem cell research.

Subject: Urge
NIH to increase funding and support for human embryonic stem cell research and
new stem cell research investigator
Dear NIH Director,
Thank you for your recent visit to San
Diego research & biotech community to promote
increasing funding for NIH and finding a cure for Parkinson’s disease (PD). Human
embryonic stem cell (hESC) cell therapy derivatives hold tremendous potential for
tissue and organ regeneration and function restoration. Clinical applications
of hESC therapy derivatives provide the
right alternative for many incurable diseases & major health problems that the conventional mode of drugs & treatments
cannot, such as heart disease and failure, Parkinson’s
diseases, ALS, Alzheimer disease, stroke, brain & spinal cord injuries. Each
single one of those world-wide major health problems cost the health care
system more than $10 billion annually. In
particular, hESC neuronal & cardiomyocyte therapy derivatives are currently
the only available human cell sources with adequate capacity to regenerate
neurons & contractile heart muscles, vital for CNS and heart repair in the
clinical setting. The loss of NIH funds to
hESC research threatens the future of existing hESC projects and the ability
for new investigators to get funding to continue hESC research and
career or begin new studies, which are crucial
to improving the human health and fighting human diseases, particularly those
major health problems of US, such as PD and heart disease.
Recent
advances and breakthroughs in San Diego Regenerative Medicine Institute (SDRMI)
hESC research have overcome some major obstacles in bringing hESC therapy
derivatives towards clinical applications. SDRMI & Xcelthera have established human stem cell technology
platforms for defined culture systems for derivation and maintenance of
clinical-grade pluripotent hESCs (PluriXcel-DCS) and lineage-specific
differentiation of pluripotent hESCs by small molecule induction for direct
conversion of pluripotent hESCs into neuronal cells or heart muscle cells for developing
safe and effective stem cell therapies (PluriXcel-SMI).
Such milestone advances and medical innovations in SDRMI & Xcelthera hESC
research enable generation of a large supply of high purity clinical-grade hESC
neuronal (Xcel-hNuP & Xcel-hNu) & heart (Xcel-hCardP & Xcel-hCM) cell therapy products for treating
neurological & heart diseases & injuries. Please go to our websites at http://www.sdrmi.org
& http://www.xcelthera.com
to see SDRMI & Xcelthera stem cell research breakthrough publications, human
stem cell therapy products and technology platforms, and watch videos of hESC
heart beats (hESC-derived heart muscle cells) & slideshow of evolution of
CNS neuron cells from hESCs by SDRMI & Xcelthera exclusive human stem cell
technique PluriXcel-SMI.
Increasing
current NIH funding for hESC research is vital to driving the advance of
medicine to provide treatment options for many major world-wide incurable diseases,
such as Alzheimer disease, Parkinson’s disease, ALS, heart disease. Given the
limited capacity of the CNS & heart for self-repair, transplantation of
hESC neuronal & heart cell therapy derivatives holds enormous potential in cell replacement
therapy, representing most
promising therapeutic approaches closest to provide a
cure. Increasing funding for hESC research would be crucial to relieving
health care burden, therefore, budget deficit in the future. However, although
President Obama acted very quickly to relax the NIH policy on hESC research in
March 2009, so far NIH under your directing have cut funding for hESC research
to a level worse than that under pervious Bush administration by a Republican
President or previous NIH director. During Obama administration led by a
Democrat President, crucial hESC research and advances cannot proceed, and
existing national hESC research labs and resources that had been open for
research progress even in Bush administration have been shut down due to lack
of funding. On the other hand, NIH under your directing have wasted hundreds of
millions of taxpayer money on adult stem cell frauds and scams and fake science,
such as on making very dangerous malicious cancer cells from skin by calling it
as induced pluripotent stem cells (iPS cells, no scientific evidence for
self-renewal by the definition of stem cells) to endanger public health. In
last few years, NIH under your directing have wasted > $300 millions on iPS
cells (putting oncogenes into the skin cells of lab rats by falsely claiming it
as adult cell alternate for hESCs), examples include Deepak Srivastava of USF
(NIH U01HL100406) ~ $ 7 million, George Daley
of Harvard U. (NIH U01HL100001) ~ $ 7 million,
Robert Robbins of Stanford U (NIH U01HL099776) ~ $ 7 million, Charles
Murry of U. Washington
(NIH P01HL094374) ~ $ 10 million, Alysson Muotri of UCSD (NIH 1DP2OD006495) ~ $5 million, John O'Shea of National Institute of Arthritis And
Musculoskeletal And Skin Diseases
(NIH 1ZICAR041190) ~ $ 14 million. While funding for hESC research has been
reduced from ~ $80 millions in Bush administration to < 10 millions annually
in Obama administration. Please see this website http://search.engrant.com for more information. As NIH new
investigator, my critical hESC research projects relevant to understanding the
human development and fighting human diseases & major US health problems,
such as heart diseases and PD, have kept receiving NIH flawed reviews with
apparent biases/COI and scores not reflecting the overall impact
and scientific merit of hESC research grant applications. Therefore, we’d like to urge NIH to take
action to have high level of transparency and high standard of review for NIH
grants review processes in Center for Scientific Review, particularly for stem
cell research projects, increase NIH funding for hESC research and new stem
cell research investigator, and stop funding stem cell frauds & scams &
fake science with taxpayer money.

CIRM Continue to Cover Up Unlawful Practice By Using Biased Pre-Application to Deny Prop71 Funding for Stem Cell Research But Give Conflicts of Interest Preferential Treatment
If anyone wants to see hard core denial, California
Institute for Regenerative medicine (CIRM) would be a very good example. Although
evidences and signs of conflicts of interest (COI) in CIRM RFAs, grant reviews,
and awards have been widespread and as red as monkey’s butt, the only people
who cannot see their COI are CIRM themselves, the only people who think their
red butt has been well covered are CIRM themselves. So far, CIRM president Alan
Trounson has totally denied there were any COI in CIRM grant reviews and
awards. Recently, it seems CIRM chair Jon Thomas finally stepped ahead of Alan
Trounson to address potential conflicts within this agency to appeal to the
press. However, for CIRM applicants who have long been tired of hearing ICOC
and CIRM press releases to screw hundreds of millions of Prop 71 together with stem
cell research and scientific integrity beyond the justification of any ethics
and research integrity committee, nothing has changed. If anyone predicted that
human embryonic stem cell (hESC) research would possibly lose competition to
MSC junk cells, tissue adult cells, disease cells, iPS cell scam, and fake
science in applying for funding from a Proposition for hESC research, probably
no one would believe it. But that is the today’s reality, that is what CIRM did
with their unfair competition practice to CA $1.5 billion awards of Prop 71 in
front of an oversight committee that comprises Dean, President, CEO of CA most prestigious
universities and research institutions who represent the best of a society can
offer.
CIRM RFA 13-01 LOI: Application Number: DR3-07198
Project Title: Clinical
Development
of Human Embryonic Stem Cell (hESC) Neuronal Therapy Derivatives for Nerve Regeneration Following Spinal Cord
Injury (SCI)
Project Summary: There is a large
unfulfilled healthcare need to provide treatment to improve the neurologic and
motor functions following SCI. Human stem cell transplantation represents a
promising therapeutic approach closest to provide a cure to restore the normal
nerve tissue and function. However, to date, the lack of a clinically-suitable
source of engraftable human stem/progenitor cells with adequate neurogenic
potential has been the major setback in developing safe and effective cell-based
therapies for regenerating the damaged or lost CNS structure and circuitry. Despite
some beneficial outcomes, the prototypical neuroepithelial-like nestin-positive
neural stem cells (hNSCs) appeared to exert their therapeutic effect primarily
by their non-neuronal progenies through producing trophic and/or
neuro-protective molecules to rescue endogenous host neurons, but not related
to regeneration from the graft or host remyelination. Pluripotent human
embryonic stem cells (hESCs) proffer cures for a wide range of neurological
disorders by supplying the diversity of human neuronal cell types in the
developing CNS for repair. However, realizing the therapeutic potential
of hESC derivatives has been hindered by conventional approaches for generating
functional cells from pluripotent cells through uncontrollable, incomplete, and
inefficient multi-lineage differentiation that is often followed by phenotypic
heterogeneity and instability, hence, a high risk of tumorigenicity. To
overcome the major obstacles in therapeutic application of hESCs, we have established human stem cell
technology platforms for defined culture systems for derivation and
maintenance of clinical-grade pluripotent hESCs (PluriXcel-DCS) and lineage-specific differentiation of
pluripotent hESCs by small molecule induction for direct conversion of
pluripotent hESCs into neuronal progenitors and neuronal cells that are highly
neurogenic in vitro and in vivo (PluriXcel-SMI), which dramatically increases the clinical efficacy
of graft-dependent repair and safety of hESC-derived cellular products. This
technology breakthrough enables well-controlled efficient generation of a large
supply of high purity clinical-grade hESC neuronal derivatives (Xcel-hNuP &
Xcel-hNu) with adequate capacity for CNS regeneration as cell therapy products
to be translated to patients in clinical trials for nerve regeneration and
neuronal function restoration following SCI. The objective of this stem cell
therapy development project is to file IND
for hESC neuronal therapy derivatives as treatments for SCI to obtain FDA
approval for first-in-human studies, and to complete early phase clinical
trials designed to test safety and clinical efficacy of hESC neuronal therapy
derivatives in treating SCI-resulted paralysis. Clinically-suitable hESC
neuronal derivatives will be cGMP manufactured and transplanted into both acute
and chronic paraplegic patients with complete SCI. Clinical trials will be
designed to evaluate primarily safety in humans as well as provide preliminary
evidences of effectiveness for nerve regeneration and motor function
improvement that could lead to more definitive clinical efficacy studies. Fulfilling
the goal of this project will lead to safe and effective hESC-based
regenerative therapies as optimal treatment options for tissue and function
restoration following SCI. The outcome of this project will have a
transformative impact on improving the function, wellness, and overall quality
of life.
Our Response to CIRM: This CIRM RFA does
not require PreIND meeting, part of the goal is to have the meeting and file an
IND. San Diego Regenerative Medicine Institute (SDRMI) hESC neuronal & cardiomyocyte therapy derivatives are currently the
only available human cell sources with adequate capacity to regenerate neurons
& contractile heart muscles, vital for CNS and heart repair in the clinical
setting. CIRM are giving CIRM board member applicants preferential
treatment, such as they only need to file a IND (does not even matter what kind
of IND, if the IND has anything to do with Prop 71, or if they are in CA or not,
so long as they connect to somebody in CIRM), we have to have pre-IND meeting
with our Prop 71 IND since we do not have any member on board to speak for us,
not consistent with Prop 71 equal and fair competition review criteria. CIRM have
been withholding Prop 71 from CA human embryonic stem cell (hESC) research and
facility, such as deny consideration against Prop 71 for our grant applications
targeting for heart and neurological diseases in accordance with Prop 71
pursuant to Prop 71 and consistent with Prop 71 (e.g., TR4-06762; DR2-05339;
TR3-05505; RB4-06272). We have all our scientific data ready to file an IND , wait for CIRM to
give us lawful Prop 71 fund to do that. We said in the LOI, whenever CIRM is
going to dole out Prop 71 in accordance with Prop 71 pursuant to Prop 71 and
consistent with Prop 71 to us, whenever we are planning to file an IND immediately. That
CIRM continue to deny Prop71 funding for our urgent hESC research & therapy
while give COI preferential treatment is telling those patients in need of Prop
71 hESC therapy and treatment to wait because CIRM are embezzling CA stem cell
research fund to waste on CIRM board members’ luxury salaries and conflicts of
interest and fake science without competition. We said that 3 years ago, said
it again 2 years ago, said in ICOC meeting, and said it again in this RFA. It
is CIRM board COI members like you have been trying to delay Prop 71 mission.
By the way, my former
mentors Dr. Evan Snyder of Sanford Burnham & Dr. Jean Loring of Scripps
& others (5) have close connection with Dr. Larry Goldstein & others of
UCSD and CIRM president Alan Trounson & his human cloning company ISCO in
Carlsbad and majority of CIRM board members such as CIRM vice chair/UC connect
CEO Duane Roth & Roth Capital & Biomed Realty (BMR), & have severe
conflicts of interest with San Diego Regenerative Medicine Startup. My former
mentors and Larry Goldstein are all stem cell center directors and prestigious
professors, they have been giving us a hard time in terms of stem cell faculty
& resource sharing of Sanford Consortium, using their basic mentor &
director duty such as providing reference letter, collaboration, resource coordination,
stem cell meeting organization as their bargaining chips for preferential
treatment of CIRM funding and public stem cell resources to themselves &
their associates. Although we are welcome resource sharing and collaboration of
Sanford
consortium, my mentors and their institutions had voluntarily withdrawn their
supports, therefore, withdrawn their rights to my stem cell research. I am sure
they are prestigious professors & directors like the majority of those on
CIRM board, should have their integrity not to take the advantage of
Regenerative Medicine startup and get preferential treatment for hundreds of
millions of CIRM funding & resources using their stem cell center director
position and connection with CIRM board members.

We have
reviewed the LOI submitted in response to RFA 13-01, Disease Team Therapy
Development Awards. Unfortunately, your proposal does not meet the eligibility
requirements described for this RFA and therefore we cannot accept the LOI. The
project was found to not yet be at an eligible and competitive stage of
readiness for this RFA. For example, a PreIND meeting has not yet been
conducted the outcomes of which are critically important in developing a
competitive proposal. The information you provided was carefully reviewed by
our clinical development and early translation teams and presented to the CIRM

CIRM Embezzle $32 million CA Stem Cell Research Fund to Bank Fake Science in UC and Out of State
CIRM
(California Institute for Regenerative Medicine) withhold Prop 71 from CA human
embryonic stem cell (hESC) research and facility, such as our grant
applications targeting for heart and neurological diseases in accordance with
Prop 71 pursuant to Prop 71 and consistent with Prop 71 (e.g., TR4-06762; DR2-05339; TR3-05505; RB4-06272). San

On the other hand, CIRM
embezzle CA stem cell research fund to conflict of interest in UC and out of
state to waste on banking stem cell frauds and scams. Abnormal iPS cells are made
from adult skin cells and disease tissues have nothing to do with stem cell
research of Prop 71. Anyone in his/her right state of mind would believe such ridiculous
fake science that disease tissues would make any stem cells as CIRM press
release claimed, which would make CIRM communication officer Kevin McCormack of no moral integrity sound
very much like a stem cell con man. Why would CIRM waste ~$32 million
taxpayers’ money to have those UC and out of state researchers to collect
disease tissues and bank disease cells? CIRM gave $10 M CA bond to Coriell
Institute for Medical Research & $16 M more CA bond to Cellular Dynamics
International of Jamie Thomson, both company are outside of California . Is it obvious that the only
reason they got the multi-millions of awards from California stem cell agency
is their connection with somebody on CIRM board, such as CIRM chair Jon Thomas
& top officials with these out state company Florida WSCS meeting & NIH
director personalized medicine & iPS center director Dr. Rao for banking
into CIRM Buck Institute resources. While other CIRM resources so far have been
withholding California stem cell research resources & infrastructure built
with > $300 millions of state fund, such as Sanford Consortium for
Regenerative Medicine & UC Stem Cell Centers, from stem cell research,
turning those expensive state stem cell center buildings into few UC
professors’ penthouses, visibly vacant of any stem cell research, no recruiting
or collaborating or sharing activities with any stem cell research expertise
who have demonstrated achievement in the area of pluripotent stem cell &
progenitor cell biology & medicine according to Prop 71, wasting state fund
and resources enormously.
