Realizing the potential of stem cell therapy: Studies report progress in developing treatments for diseases and injuries

ScienceDaily (Oct. 15, 2012) New animal studies provide additional support for investigating stem cell treatments for Parkinson's disease, head trauma, and dangerous heart problems that accompany spinal cord injury, according to research findings released today.

The work, presented at Neuroscience 2012, the annual meeting of the Society for Neuroscience and the world's largest source of emerging news about brain science and health, shows scientists making progress toward using stem cell therapies to repair neurological damage.

The studies focused on using stem cells to produce neurons -- essential, message-carrying cells in the brain and spinal cord. The loss of neurons and the connections they make for controlling critical bodily functions are the chief hallmarks of brain and spinal cord injuries and of neurodegenerative afflictions such as Parkinson's disease and ALS (amyotrophic lateral sclerosis), also known as Lou Gehrig's disease.

Today's new findings show that:

Other recent findings discussed show that:

"As the fields of developmental and regenerative neuroscience mature, important progress is being made to begin to translate the promise of stem cell therapy into meaningful treatments for a range of well-defined neurological problems," said press conference moderator Jeffrey Macklis, MD, of Harvard University and the Harvard Stem Cell Institute, an expert on development and regeneration of the mammalian central nervous system. "Solid, rigorous, and well-defined pre-clinical work in animals can set the stage toward human clinical trials and effective future therapies."

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

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).

Zannos Grekos

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.

Yamanaka and the Frailty of Peer Review


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'


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.”
