RBCC: Could Stem Cells Be Key to Promising Autism Therapy?

Tuesday, October 16th, 2012

NOKOMIS, Fla.--(BUSINESS WIRE)--

Rainbow Coral Corp. (RBCC) subsidiary Rainbow BioSciences will keep a close eye on a new study that could potentially lead to stem cell therapies for children with autism.

Researchers have been given the go-ahead by the FDA to launch a small study evaluating the effectiveness of autism treatments using patients own umbilical cord blood. Thirty children, aged two to seven, will receive injections of their own stem cells from the cord blood banked by their parents at birth.

Scientists will evaluate whether the stem cell therapy helps improve language and behavior in the children. Although the cause of autism is unknown and there is no cure for the disorder, one theory suggests that autism occurs because cell in the brain, known as neurons, are not connecting normally. Its possible that stem cells may address this problem.

RBCC is working to capitalize on the rising demand for effective new stem cell treatments by bringing a potentially game-changing stem cell technology to market. The company is close to a deal with Regenetech to acquire a license to perform cell expansion using that companys Rotary Cell Culture SystemTM, a rotating-wall bioreactor originally developed by NASA.

The rotating-wall bioreactor is capable of multiplying functional, 3-D stem cells for use in a variety of research projects, said RBCC CEO Patrick Brown. Stem cells carry tremendous potential to help researchers develop new treatments and cures for devastating diseases from Parkinsons to Alzheimers and even autism, but much research must be done first. Consequently, were very optimistic about the market potential for this revolutionary bioreactor technology.

RBCC plans to offer the new technology to help kickstart billions of dollars worth of research in an industry currently dominated by Amgen, Inc. (AMGN), Celgene Corporation (CELG), Genzyme Corp. (NASDAQ:GENZ) and Gilead Sciences Inc. (GILD).

State licensing hearing for Bonita Springs stem cell doctor to begin Tuesday

Monday, October 15th, 2012

The Grekos hearing is scheduled to begin at 9 a.m. Tuesday in the Martin Luther King, Jr. Administration Building, room 1-140A, 5775 Osceola Trail, Naples. It is scheduled for four days.

BONITA SPRINGS Bonita Springs physician Zannos Grekos, whose license is in jeopardy for controversial stem cell therapy, is getting his day before a judge.

Barring a last-minute delay or settlement, an administrative hearing is scheduled to begin Tuesday in Naples for the 47-year-old. He is fighting to get his license back in good standing from a suspension order, while the state Department of Health is pursuing more discipline and potentially revocation of his license.

Trained as a cardiologist, he's been licensed in Florida since 1996.

The trial-like proceeding, without a jury, is scheduled for four days before an administrative law judge. The proceeding is open to the public. The case against Grekos has garnered considerable media attention, including CNN and inquiries from European media.

A Texas father, Jimmy Bell, will be tracking what happens. Last year, he paid $57,000 upfront for his 5-year-old son, Jason, to undergo stem cell therapy to fight pulmonary hypertension. Despite pleas that his boy was weakening by the day, the treatment was never scheduled and Jason died. Bell received a $10,000 refund.

"He's taking advantage of people and it's more for personal gain," Bell said. "I'd like to see that stopped."

The hearing has been rescheduled numerous times since the state issued an emergency restriction against Grekos in February 2011. Authorities restricted his license and told him not to do any treatment with patients which involve bone marrow or stem cells.

The rest is here:

Yamanaka and the Frailty of Peer Review

Sunday, October 14th, 2012


More than one back story exists on
Shinya Yamanaka and his Nobel Prize, but one that has received little
attention this week also raises questions about hoary practice of
peer review and publication of research – not to mention the
awarding of billions of dollars in taxpayer dollars.

The Yamanaka tale goes back to a 2010
article in the New Scientist magazine by Peter Aldous in which the
publication examined more than 200 stem cell papers published from
“2006 onwards.” The study showed an apparent favoritism towards
U.S. scientists. Also specifically reported were long delays in
publication of Yamanaka's papers, including in one case 295 days.
Here is part of what Aldous wrote,

“All's fair in love and war, they
say, but science is supposed to obey more noble ideals. New findings
are submitted for publication, the studies are farmed out to experts
for objective 'peer review' and the best research appears promptly
in the most prestigious journals. 

“Some stem cell biologists are crying
foul, however. Last year(2009), 14 researchers in this notoriously
competitive field wrote
to leading journals
 complaining of "unreasonable or
obstructive reviews". The result, they claimed, is that
'publication of truly original findings may be delayed or rejected.' 

“Triggered by this protest, New
Scientist scrutinised the dynamics of publication in the most
exciting and competitive area of stem
cell research
, in which cells are 'reprogrammed' to
acquire the versatility of those of an early-stage embryo. In this
fast-moving field, where a Nobel prize is arguably at stake,
biologists are racing feverishly to publish their findings in top
journals. 

“Our analysis of more than 200
research papers from 2006 onwards reveals that US-based scientists
are enjoying a significant advantage, getting their papers published
faster and in more prominent journals (find
our data, methods and analyses here
). 

“More mysterious, given his standing
in the field, is why two of Yamanaka's papers were among the 10 with
the longest lags. In the most delayed of all, Yamanaka reported that
the tumour-suppressing gene p53 inhibits the formation of
iPS cells. The paper took 295 days to be accepted. It was eventually
published by Nature in August 2009 alongside four similar
studies. 'Yamanaka's paper was submitted months before any of the
others,' complains Austin
Smith
 at the University of Cambridge, UK, who coordinated
the letter sent to leading journals. 

“Yamanaka suggests that editors may
be less excited by papers from non-US scientists, but may change
their minds when they receive similar work from leading labs in the
US. In this case, Hochedlinger submitted a paper similar to
Yamanaka's, but nearly six months after him. Ritu
Dhand
, Nature's chief biology editor, says that each paper
is assessed on its own merits. Hochedlinger says he was unaware of
Yamanaka's research on p53 before publication.”

Last week, Paul Knoepfler of UC Davis
wrote of other issues dealing with peer review, but coincidentally
also dealing with iPS cells. What New Scientist and Knoepfler are
discussing is not an isolated situation. It is part of a continuum of
complaints, both serious and self-interested but exceedingly
pervasive. A Google search today on the term “problems with peer
review” turned up 10.1 million references.  Writing on Ars Technica last year, Jonathan Gitlin, science policy analyst at the National
Human Genome Research Institute
,  summarized many of the issues, citing a “published” (our quotation marks)
study that said peer review doesn't work “any better than chance.”
Gitlin said,

“A common criticism is that peer
review is biased towards well-established research groups and the
scientific status quo. Reviewers are unwilling to reject papers from
big names in their fields out of fear, and they can be hostile to
ideas that challenge their own, even if the supporting data is good.
Unscrupulous reviewers can reject papers and then quickly publish
similar work themselves.” 

At the $3 billion California stem cell
agency, peer review is undergoing some modest, indirect examination
nowadays. The agency is moving towards tighter scrutiny of budgets
proposed by applicants. And, following a record wave of appeals this
summer by disgruntled applicants rejected during peer review, it is
also moving to bring the appeal process under more control.
As the agency tries to move faster and
more successfully towards development of commercial therapies, it may
do well to consider also the frailties of its peer review process and the
perils of scientific orthodoxy.

Yamanaka: ‘Rejected, Slow and Clumsy’

Sunday, October 14th, 2012


This week's announcement of the Nobel
Prize
for Shinya Yamanaka brought along some interesting
tidbits, including who was “snubbed” as well as recollections
from the recipient.

Jon Bardin of the Los Angeles Times
wrote the “snubbed” piece and quoted Christopher Scott of
Stanford and Paul Knoepfler of UC Davis about the selection issues.
Bardin's piece mentioned Jamie Thomson and Ian Wilmut as scientists
who also could have been considered for the award but were not named.
Ultimately, Bardin wrote that the award committee was looking for a
“singular, paradigm shifting discovery,” which he concluded was
not the case with Thomson or Wilmut.
How Yamanaka arrived at his research
was another topic in the news coverage, much of it dry as dust.
However, Lisa Krieger of the San Jose Mercury News began her story
with Yamanaka's travails some 20 years ago. At the time, no one was returning his phone
calls as he looked for work, and he was rejected by
50 apparently not-so-farsighted American labs.
But that job search in 1993 came only after Yamanaka
decided he was less than successful as an orthopedic surgeon,
according to an account in JapanRealTime. “Slow and clumsy” was
how Yamanaka described himself.
And so he moved on to research. But
again he reported stumbling. In this case, he found a way to reduce
“bad cholesterol” but with a tiny complication – liver cancer.
That in turn sent him on a journey to learn how cells proliferate and
develop, which led him to the work that won the Nobel Prize.
Yamanaka said his original interest in
orthopedic medicine was stimulated by his father along with the treatments
for injuries young Yamanaka received while playing rugby and learning judo. The JapanRealTime account continued,

“'My father probably still thinks in
heaven that I’m a doctor,' he said in the interview(with Asahi
Shimbun
last April). 'IPS cells are still at a research phase and
have not treated a single patient. I hope to link it to actual
treatment soon so I will be not embarrassed when I meet my father
someday.'”

And then there was, of course, the much-repeated story from the researcher who shared the Nobel with Yamanaka, John Gurdon. He has preserved to this day a
report from a high school biology teacher that said the 15-year-old
Gurdon's desire to become a scientist was “quite ridiculous.”
The teacher, who is unnamed, wrote,

“If he can’t learn simple
biological facts he would have no chance of doing the work of a
specialist, and it would be a sheer waste of time, both on his part
and of those who would have to teach him.”

Yamanaka and the Golden State

Sunday, October 14th, 2012


The iPierian biopharmaceutical company
in South San Francisco was quick to make a change in its web site
this morning after the Nobel Prize for medicine was announced.

Altered was the bio for one of its
scientific advisors, Shinya Yamanaka, to note that he had won the
Nobel. The bio is tucked away on the site, but it is likely that the
company, which specializes in iPS work, will figure out how to put
the news out front on its home page as well as issue a press release.
It was all part of the reaction today
in California to the Nobel for Yamanaka, who has substantial links to
the Golden State, including UCSF and the Gladstone Institutes.
Both enterprises moved with greater
deftness than iPierian. Yamanaka is a professor at UCSF and a senior
investigator at Gladstone, and the organizations quickly put together a news conference this morning that featured Yamanaka on a video
hook-up from Japan.
UCSF, which is allied with Gladstone,
issued a press release that quoted the president of Gladstone, R.
Sanders Williams
, who also mentioned the California stem cell agency.
Williams said,

“Dr. Yamanaka’s story is a
thrilling tale of creative genius, focused dedication and successful
cross-disciplinary science. These traits, nurtured during Dr.
Yamanaka’s postdoctoral training at Gladstone, have led to a
breakthrough that has helped propel the San Francisco Bay Area to the
forefront of stem cell research. Dozens of labs — often supported
by organizations such as the California Institute for Regenerative
Medicine (CIRM)
and the Roddenberry Foundation–have adopted his
technology.” 

CIRM, which is the state's $3 billion
stem cell effort, published an item on its blog quoting CIRM
President Alan Trounson. He said,

"There are few moments in science
that are undisputed as genuine elegant creativity and simplicity.
Shinya Yamanaka is responsible for one of those. The induced
pluripotent stem cells he created will allow us to interrogate and
understand the full extent and variation of human disease, will
enable us to develop new medicines and will forever change the way
science and medicine will be conducted for the benefit of mankind. An
extraordinary accomplishment by a genuinely modest and brilliant
scientist. He absolutely deserves a Nobel award.”

The CIRM item by Amy Adams, the
agency's communications manager, said that just five years after
Yamanaka's research,

“CIRM alone is funding almost $190
million in awards developing better ways of creating iPS cells and
using those cells to develop new therapies (the
full list of iPS grants is on our website
).”

One of the recipients of CIRM's iPS
cash is the well-connected iPierian, which has taken in $7.1 million.
Yamanaka, however, has never received a grant from the agency, and
it is not known whether he ever applied since CIRM releases only the
names of researchers whose applications were approved.

Tighter Controls on Stem Cell Grant Budgets Hits Quorum Bump

Sunday, October 14th, 2012


SAN FRANCISCO – A move to tighten
budget controls on grants from the $3 billion California stem cell
agency stalled Monday, but it appears that the plan is headed for
ultimate approval.

The proposal was up for consideration
by the agency's directors' Science Subcommittee, which could not act
on it after it lost its quorum.
Members of the panel generally favored
the stronger budget controls, but had questions about the specifics
of implementing the plan during closed-door reviews of grant
applications. The proposal is likely to be altered to respond to
those concerns. It would then either come back to the Science
Subcommittee or go to the full board.
The plan would make it clear to
recipients of large grants that approval of an application by the
agency's governing board does not provide a carte blanche to
researchers. Ellen Feigal, senior vice president for research and
development, said it can be “extremely difficult” for CIRM staff
to deal with budget problems in grants following board approval.
The committee also approved a plan to
speed the application process on its next disease team round, which
is aimed at driving research into the clinic. The concept proposal
for that round is scheduled to come before directors later this
month. The round will be limited to “more mature stage” research
that is close to a clinical trial, if not in one. Feigal said 10 to
15 applications are expected.
Another proposal to add more millions
to CIRM's strategic partnership program was also approved.

Stem Cell Orthodoxy and Peer Review

Sunday, October 14th, 2012


Going against the grain can be
difficult as UC Davis stem cell scientist Paul Knoepfler learned
again in connection with his research that dealt with similarities
between cancer and iPS cells.

His “unsettling” findings troubled
some scientists who reviewed his paper prior to its publication in
September in Stem Cells and Development. (See here and here.)
As many readers know, iPS or
reprogrammed adult cells are currently a hot research avenue in stem
cell research because they avoid many of the ticklish ethical and
political problems connected with human embryonic stem cells.
Knoepfler shared his thoughts on the
publication and peer review process on his blog last week. He wrote,

“Not surprisingly...there are certain
members of the stem cell field who would rather focus away from the
ideas that iPS cells are similar in some respects to cancer.”

Knoepfler, whose research was financed
in part by the California stem cell agency, wrote,

“Once we had a manuscript together
comparing iPS cells to cancer cells, we sent it to several high
profile journals without much luck. We thought that the fact that our
data indicated that iPS cells are similar to cancer cells might make
reviewers and editors excited. We thought that the paper was novel
and thought provoking in a number of ways. At the same time I
realized the theme of the paper would be controversial. 

“I would say two general things about
the review process at the two journals that turned down the paper.
First, the reviewers at these journals were enormously helpful with
their suggestions and helped us improve the paper substantially.
Second, they were clearly very uncomfortable with the notion that iPS
cells are related in some ways to cancer so unsettled in fact that I
believe it influenced their reviews.”

At one journal, a reviewer said the
findings were either “not sufficiently novel” or “trivial.”
“Little useful insights” said another. And a third said, “many
unsettling results....”
Knoepfler commented on this blog,

“Yeah, it may be unsettling that iPS
cells share traits with cancer cells, but if that is the reality,
isn’t it important that people know that and think about it, talk
about it, and address the issue with eyes open?”

Knoepfler's item and similar comments
from other researchers that can found elsewhere on the Internet
indirectly raise questions about the California stem cell agency's process
of peer review of applications for hundreds of millions of dollars in
funding, especially in the wake of this summer's unprecedented rash of appeals of decisions by grant reviewers.
The key question is whether the agency's closed-door process reinforces orthodoxy or, in fact, is all but controlled by what
amounts to scientific conventional wisdom. Obviously, no researcher
likes to see a paper rejected or a grant denied. But the record
number of appeals at CIRM and other private complaints could well indicate
that potentially profitable proposals are receiving a less than
welcome reception behind closed doors from agency reviewers.
The agency's board itself is
hard-pressed to make such determinations. It is hamstrung by
procedures that do not permit it to expand an application directly –
only a staff-written summary. Names of applicants and institutions
are censored, although the board is required by law to discuss in
public most aspects of a research proposal. Exceptions are permitted for proprietary information. Additionally, a handful of the 29 members of the governing board do participate in the reviews, which come before final action by the board. 
Currently the agency is pushing hard to
commercialize stem cell research and fulfill at least some of the
promises to voters that were made in 2004. To do that, the agency may
well have to step outside of the normal comfort zone of the good
burghers of stem cell science.

agency's communications manager, said that just five years after
Yamanaka's research,

“CIRM alone is funding almost $190
million in awards developing better ways of creating iPS cells and
using those cells to develop new therapies (the
full list of iPS grants is on our website
).”

One of the recipients of CIRM's iPS
cash is the well-connected iPierian, which has taken in $7.1 million.
Yamanaka, however, has never received a grant from the agency, and
it is not known whether he ever applied since CIRM releases only the
names of researchers whose applications were approved.

Stem Cell Orthodoxy and Peer Review

Sunday, October 14th, 2012


Going against the grain can be
difficult as UC Davis stem cell scientist Paul Knoepfler learned
again in connection with his research that dealt with similarities
between cancer and iPS cells.

His “unsettling” findings troubled
some scientists who reviewed his paper prior to its publication in
September in Stem Cells and Development. (See here and here.)
As many readers know, iPS or
reprogrammed adult cells are currently a hot research avenue in stem
cell research because they avoid many of the ticklish ethical and
political problems connected with human embryonic stem cells.
Knoepfler shared his thoughts on the
publication and peer review process on his blog last week. He wrote,

“Not surprisingly...there are certain
members of the stem cell field who would rather focus away from the
ideas that iPS cells are similar in some respects to cancer.”

Knoepfler, whose research was financed
in part by the California stem cell agency, wrote,

“Once we had a manuscript together
comparing iPS cells to cancer cells, we sent it to several high
profile journals without much luck. We thought that the fact that our
data indicated that iPS cells are similar to cancer cells might make
reviewers and editors excited. We thought that the paper was novel
and thought provoking in a number of ways. At the same time I
realized the theme of the paper would be controversial. 

“I would say two general things about
the review process at the two journals that turned down the paper.
First, the reviewers at these journals were enormously helpful with
their suggestions and helped us improve the paper substantially.
Second, they were clearly very uncomfortable with the notion that iPS
cells are related in some ways to cancer so unsettled in fact that I
believe it influenced their reviews.”

At one journal, a reviewer said the
findings were either “not sufficiently novel” or “trivial.”
“Little useful insights” said another. And a third said, “many
unsettling results....”
Knoepfler commented on this blog,

“Yeah, it may be unsettling that iPS
cells share traits with cancer cells, but if that is the reality,
isn’t it important that people know that and think about it, talk
about it, and address the issue with eyes open?”

Knoepfler's item and similar comments
from other researchers that can found elsewhere on the Internet
indirectly raise questions about the California stem cell agency's process
of peer review of applications for hundreds of millions of dollars in
funding, especially in the wake of this summer's unprecedented rash of appeals of decisions by grant reviewers.
The key question is whether the agency's closed-door process reinforces orthodoxy or, in fact, is all but controlled by what
amounts to scientific conventional wisdom. Obviously, no researcher
likes to see a paper rejected or a grant denied. But the record
number of appeals at CIRM and other private complaints could well indicate
that potentially profitable proposals are receiving a less than
welcome reception behind closed doors from agency reviewers.
The agency's board itself is
hard-pressed to make such determinations. It is hamstrung by
procedures that do not permit it to expand an application directly –
only a staff-written summary. Names of applicants and institutions
are censored, although the board is required by law to discuss in
public most aspects of a research proposal. Exceptions are permitted for proprietary information. Additionally, a handful of the 29 members of the governing board do participate in the reviews, which come before final action by the board. 
Currently the agency is pushing hard to
commercialize stem cell research and fulfill at least some of the
promises to voters that were made in 2004. To do that, the agency may
well have to step outside of the normal comfort zone of the good
burghers of stem cell science.

Regenevéda Opens Flagship Stem Cell Therapy Clinic in Beverly Hills

Friday, October 12th, 2012

Beverly Hills, CA (PRWEB) October 12, 2012

Regenevda (http://www.regeneveda.com) recently opened its brand new flagship facility in Beverly Hills. Founded by world renowned surgeon Dr. Thom Lobe, Regenevda specializes in cutting edge anti-aging treatments such as Stem Cell Therapy, IV Vitamin Therapy, and HGH Therapy.

Dr. Thom Lobe is an internationally respected surgeon and has been in practice for over 30 years. Consistently pioneering advances in medicine, Dr. Lobe was one of the first doctors to ever separate conjoined twins. Consistently working to help make advances in medicine, Dr. Lobe also has over 200 publications to his credit.

Overseeing the business aspect of Regenevda is Lindsey Combs. She is responsible for sales, staff, accounting, facility management, and business development. A graduate of the University of California, Los Angeles, Ms. Combs has been working in the anti-aging field for over 10 years and has been a California Licensed Esthetician since 2003.

Being one of the very few physicians in the country to hold the most advanced board certification (FAARM), Dr. Lobe is able to offer Stem Cell Therapy at the Regenevda clinic. Inside each persons own body, there are special cells in nearly every organ and tissue that have the ability to help heal damage. These special cells are called Stem Cells and this therapy works by harvesting these cells from a persons own blood, bone marrow, or fat and can help with different conditions. Some examples of procedures that use Stem Cell Therapy are: Stem Cell Facelifts, Stem Cell Breast Augmentation, and Stem Cell Joint Therapy. Stem Cell treatments are safe, non-invasive, and are done under local anesthesia.

Intravenous Nutrition Therapy (or IV Vitamin Therapy) is another anti-aging and rejuvenation treatment that can also help patients prevent migraines, lose weight, fight chronic infections like hepatitis, candida, lyme disease, as well as fight acute infections like the flu and mono. IV Therapy works by using intravenous solutions to deliver vitamins and minerals directly to the body cells. This bypasses the digestive system and provides a more direct method of delivery, which ensures that all of the nutrients required are delivered, allowing the patient to feel an improvement in condition almost immediately.

Human Growth Hormone (HGH) Therapy is another advanced treatment offered at Regenevda. HGH is secreted by the Pituitary gland and fuels cell growth and reproduction. This production peaks at adolescence. Over time, due to the effect of aging, the production of HGH slows down dramatically. As production declines, it makes it more difficult for the body to recover from physical and mental exertion. HGH Therapy acts as a supplement for HGH deficient adults to lessen body fat, boost lipid lineament, improve memory, promote bone density, as well as decrease risk factors that involve cardio-vascular conditions. If used at the onset of the decrease in HGH production, HGH Therapy can help curtail early aging and even be used as preventive measure against osteoporosis. A complete analysis of the patients sex hormones, evaluation of glucose regulation and functions of the adrenal gland, thyroid gland, and pancreas are performed before the treatment is administered for optimal results.

Combining decades of medical experience with the most cutting edge advances in medical technology, the Regenevda clinic looks to pave the way for the future of anti-aging treatments. The Regenevda Beverly Hills Institute of Cellular Therapy is located at 50 North La Cienega Boulevard. For any inquiries, they can be reached at 855-734-3638, or visit http://www.regeneveda.com.

About Regenevda :

Regeneveda, home of The Beverly Hills Institute of Cellular Therapy, provides state-of-the-art Stem Cell Therapy. Stem Cell Therapy is an effective treatment for chronic conditions such as Arthritis, Diabetes, Chronic Sports Injuries, and Chronic Pain, but is also revolutionizing anti-aging treatments such as Breast Enhancement, Erectile Dysfunction, and Facial Aging.

StemGenex™ on Adult Stem Cell-Based Therapy for Multiple Sclerosis

Thursday, October 11th, 2012

LA JOLLA, Calif., Oct. 10, 2012 /PRNewswire/ --New research directions are being explored to find therapies for hard to treat diseases. One exciting new approach is the use of autologous Adult Stem Cells. Multiple Sclerosis (MS) is one of the many notable diseasesadult stem cell therapycould potentially impact. Multiple Sclerosis (MS) is a disorder in which an individual's own immune system attacks the 'myelin sheath'. The myelin sheath serves to protect the nerve cells within the body's central nervous system (CNS). The damage caused by MS may result in many types of symptoms including:

(Photo: http://photos.prnewswire.com/prnh/20121010/LA89802-INFO)

Currently there is no cure for MS, but MS stem cell therapiesattempt to slow the disease's progression and limit symptoms. Since adult stem cells have the ability to differentiate into many different types of cells, such as those required for proper functioning and protection of nerve cells, the use of adult stem cells for MS therapy could be of substantial value. Adult stem cells can be isolated with relative ease from an individual's own 'adipose' (fat) tissue. As a result, adult stem cell therapy is not subject to the ethical or religious issues troubling embryonic methods.

Encouragingly for MS treatment potential, scientific researchers have been studying the properties of adipose-derived stem cells. Their results from canine and equine studies suggest anti-inflammatory and regenerative roles for these stem cells. Also, further research findings suggest these adipose-derived stem cells can have specific immune-regulating properties. Markedly, clinical-based work conducted overseas has indicated that individuals suffering from MS could respond well to adipose-derived stem cell treatment, with a substantially improved quality of life.

The US based company, StemGenex, is pioneering new methods for using adipose derived adult stem cells to help in diseases with limited treatment options like MS. StemGenex has been conducting research with physicians over the last 5 years to advance adult stem cell treatment protocols for alleviating MS symptoms. StemGenex's proprietary protocol includes the use of a double activation process, which increases both the viability and the quantity of stem cells that are received in a single application.

Fingers crossed at AIIMS after stem cell transplant for MS, first in country

Monday, October 8th, 2012

Doctors at the All India Institute of Medical Sciences (AIIMS) have conducted a stem cell transplant on a multiple sclerosis (MS) patient. They believe this is the first recorded case of an autologous stem cell therapy where the donor and recipient are the same person for MS in the country.

Six months after the transplant, doctors say the spread of MS, an autoimmune disease that affects the brain and spinal cord, appears to have been contained but the therapy cannot be declared a success until the patient is monitored for at least a year.

International trials have demonstrated that this transplant can restrict the spread of the disease in advanced patients, and may even reverse symptoms in early stages in some patients.

Thirty-two-year-old Rohit Yadav, a commerce graduate from Delhi University, was diagnosed with the neurological disorder in 2010. In March this year, after trying all possible conventional treatment options, doctors at AIIMS finally decided on stem cell therapy.

Dr Kameshwar Prasad, professor of neurology who has been monitoring Yadav, said: The primary purpose of autologous stem cell transplant is to control the spread of lesions. We extract the patients own stem cells, treat and inject the stem cells back. Ever since the procedure, the patient has been completely stable. To the best of our knowledge, this is the first case of stem cell therapy for MS.

In MS, the bodys own immune system attacks the myelin sheath that coats nerves, slowly destroying the central nervous system. Symptoms range from numbness and weakness in the limbs to sudden loss of balance and coordination, blurred vision and paralysis and, at the most advanced stage, disability.

Researcher Alert: California Stem Cell Agency Tightening Budget Oversight on Grants

Sunday, October 7th, 2012


Some of California's top stem cell
researchers are going to have to sharpen their spreadsheets if they
want to win money from the state's $3 billion stem cell agency.

The agency is moving to beef up
scrutiny of the high-profile, big-ticket grant applications
that it will consider during the next several years. The effort may well extend to all grant programs. The move also makes
it clear to researchers that the CIRM staff is in the driver's seat
when it comes to budgeting on research projects.
The plan was laid out this week in a memo to directors of the California Institute for Regenerative Medicine (CIRM) by Ellen Feigal, the agency's senior vice
president for research and development. She said,

“Increasing the importance of
budgetary review will encourage applicants to propose rigorous,
realistic and vetted budgets, and will further our mission to be good
stewards of taxpayer dollars. These additions will not significantly
increase the workload burden on GWG members (grant reviewers) and
explicitly acknowledge that program goals, scientific plans, accurate budgeting and prudent spending are inextricably linked.”

The proposal comes before the CIRM
directors' Science Subcommittee next Monday and would alter the
closed-door grant review process in the following manner, according
to Feigal's memo.

• “To assist GWG review,
appropriate expertise on budget and financial matters (e.g., this
could be in the form of a specialist reviewer, or can also be
assigned to a GWG reviewer with the appropriate background and
expertise), will review applications for sound budgeting and provide
comments or questions to the GWG for consideration by the reviewers
before the reviewer’s final scores are entered.
• “If the financial/budgetary
matter potentially directly impacts on the design or feasibility of
conducting the project, the GWG may consider this issue in the
scoring; otherwise, budgetary and financial issues and questions will
not contribute to the scientific score.
• “As appropriate, review summaries
sent to the ICOC (the CIRM governing board) will identify scientific
as well as budget or other issues. To the extent endorsed by the
GWG, the review summaries will also identify potential resolution
should the ICOC approve a given award with budget issues.
• “CIRM officers should be provided
explicit discretion to consider the budget comments, as well as
budget or other issues. To the extent endorsed by the GWG, the
review summaries will also identify potential resolution should the
ICOC approve a given award with budget issues.”

Feigal's memo clearly indicates that
CIRM staff has experienced push-back from recalcitrant researchers
when efforts have been made to bring costs under control. She noted that
the agency's staff examines a research project's budget during the
“prefunding” review that follows board approval. However, Feigal
said, at that stage, “It is often challenging to make substantive
changes to the budget, based on appropriateness of study activities
and costs, given the ICOC approval at a given budget amount.”
The agency has already examined some
budgets prior to board approval. One grant review in a $200
million-plus round this summer, for example, declared that costs to
prepare regulation packages had “overlap” and were “excessive,”
along with costs dealing with manufacturing and per patient expenses.
That was for a high-scoring application by Antoni Ribas of UCLA, and
he was not alone.
In her memo, Feigal listed other cases
of budgetary shortcomings in recent applications:,

• “Budget does not align with the
program deliverables and milestones. For example, the budget
includes activities not relevant to project objective(s) or that are
out of scope.
•”Budget does not contain adequate
expenses for known costs. For example, an applicant may budget
$100,000 for a GMP manufacturing run of a biologic in which it is
generally accepted knowledge that the actual expenses are typically
much greater.
•“Budget item significantly exceeds
a known cost or seems excessive without adequate justification. For
example, an applicant may propose a surgical expense of $100,000 per
patient for a procedure with Medicare reimbursement set at $15,000.
•“Cost allocations are not done
properly. For example, an applicant is developing the same
therapeutic candidate for 3 indications, and is applying for CIRM
funding for 1 of the 3, but is charging CIRM for the cost of the
entire manufacturing run.”

Initially, the budgetary review would
be used in disease team, early translational, strategic partnership
rounds, and any new rounds “as deemed appropriate.” Feigal said,
however, that “all applications for CIRM awards should be
carefully examined for budgetary appropriateness.”
Our take: This seems to be a
well-advised move, albeit one that is not likely to find favor with
researchers accustomed to loose oversight. It moves budgetary review
to an earlier stage and gives the CIRM directors a chance to weigh in
on those matters prior to approval of grants, instead of creating a
sense of entitlement on the part of recipients that may pop up
following board approval of their applications. Indeed, the plan
makes such good sense that it raises the question why it was not in
place years ago.
A final note: Feigal's memo is an
excellent example of the type of information that clarifies issues
and helps CIRM directors make the best possible decisions. It
provides some history, good evidence for a change and an explanation
of benefits. Additionally, the memo is timely, having been posted on
the CIRM website sufficiently in advance of next week's meeting to give affected parties and others time to comment
and make constructive suggestions. The memo is also far superior to
the Power Point presentations that are often submitted to the board
minus any nuanced, written discussion of the issue at hand.
Next week's meeting will be based in
San Francisco but also has teleconference locations in Irvine (2), La
Jolla, Stanford, Pleasanton, Oakland and Los Angeles where the public
and researchers can participate. The specific addresses can be found on the agenda.

UCD’s Knoepfler’s ‘Somewhat Provocative Paper’ on iPS

Sunday, October 7th, 2012


UC Davis researcher Paul Knoepfler is
the rare stem cell scientist who blogs about his work as well as
writing about issues in the field.

Over the weekend, he posted an item on
what he described as a “somewhat provocative paper” published by his lab in
“Stem Cells and Development.”  He said the paper argued
that iPS cells “are very similar in some ways to cancer cells.”
Most of his item deals with the
technical details and background of the research. But at the end of
this item, Knoepfler wrote,

“So what does this mean in the big
picture? 

“I believe that iPS cells and cancer
cells are, while not the same, close enough to be called siblings. As
such, the clinical use of iPS cells should wait for a lot more study.
Even if scientists do not use iPS cells themselves for transplants,
but instead use differentiated derivatives of iPS cells, the risk of
patients getting malignant cancers cannot be ignored. 

“At the same time, the studies
suggest possible ways to make iPS cells safer and support the notion
of reprogramming cancer cells as an innovative new cancer therapy. 

“Stay tuned in the next few days for
part 2 where I will discuss what this paper went through in terms of
review, etc. to get published. It wasn’t a popular story for some
folks.”

The UC Davis press release on the
research, which was financed by the California stem cell agency and the NIH,  was picked up by several online sites, including Redorbit,
Medicalexpress and geekosystem.

Study Sheds Light on Bone Marrow Stem Cell Therapy for Pancreatic Recovery

Thursday, October 4th, 2012

Newswise LOS ANGELES (Oct. 2, 2012) Researchers at Cedars-Sinais Maxine Dunitz Neurosurgical Institute have found that a blood vessel-building gene boosts the ability of human bone marrow stem cells to sustain pancreatic recovery in a laboratory mouse model of insulin-dependent diabetes.

The findings, published in a PLoS ONE article of the Public Library of Science, offer new insights on mechanisms involved in regeneration of insulin-producing cells and provide new evidence that a diabetics own bone marrow one day may be a source of treatment.

Scientists began studying bone marrow-derived stem cells for pancreatic regeneration a decade ago. Recent studies involving several pancreas-related genes and delivery methods transplantation into the organ or injection into the blood have shown that bone marrow stem cell therapy could reverse or improve diabetes in some laboratory mice. But little has been known about how stem cells affect beta cells pancreas cells that produce insulin or how scientists could promote sustained beta cell renewal and insulin production.

When the Cedars-Sinai researchers modified bone marrow stem cells to express a certain gene (vascular endothelial growth factor, or VEGF), pancreatic recovery was sustained as mouse pancreases were able to generate new beta cells. The VEGF-modified stem cells promoted growth of needed blood vessels and supported activation of genes involved in insulin production. Bone marrow stem cells modified with a different gene, PDX1, which is important in the development and maintenance of beta cells, resulted in temporary but not sustained beta cell recovery.

Our study is the first to show that VEGF contributes to revascularization and recovery after pancreatic injury. It demonstrates the possible clinical benefits of using bone marrow-derived stem cells, modified to express that gene, for the treatment of insulin-dependent diabetes, said John S. Yu, MD, professor and vice chair of the Department of Neurosurgery at Cedars-Sinai, senior author of the journal article.

Diabetes was reversed in five of nine mice treated with the injection of VEGF-modified cells, and near-normal blood sugar levels were maintained through the remainder of the six-week study period. The other four mice survived and gained weight, suggesting treatment was beneficial even when it did not prompt complete reversal. Lab studies later confirmed that genetically-modified cells survived and grew in the pancreas and supported the repopulation of blood vessels and beta cells.

Anna Milanesi, MD, PhD, working in Yus lab as an endocrinology fellow, is the articles first author. The researchers cautioned that although this and other related studies help scientists gain a better understanding of the processes and pathways involved in pancreatic regeneration, more research is needed before human clinical trials can begin.

Insulin-dependent diabetes occurs when beta cells of the pancreas fail to produce insulin, a hormone that regulates sugar in the blood. Patients must take insulin injections or consider transplantation of a whole pancreas or parts of the pancreas that make insulin, but transplantation carries the risk of cell rejection.
