LOS ANGELES (Oct. 2, 2012) Researchers at Cedars-Sinai's 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 diabetic's 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 Yu's lab as an endocrinology fellow, is the article's 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.

Cedars-Sinai study sheds light on bone marrow stem cell therapy for pancreatic recovery

New study sheds light on bone marrow stem cell therapy for pancreatic recovery

Lesley Kelly, 45, underwent stem cell therapy to repair scar tissue buildup in her right arm. (Cytori Therapeutics, Inc.)

By Lara Salahi, ABC News For more than 40 years, Lesley Kelly of Glasgow, Scotland, lived with third-degree burns that stretched over 60 percent of her body.

Kelly was 2 years old when she fell into a bathtub filled with hot water that scorched most of the right side of her body. She lost full range of motion around many of her joints.

"When you have bad scarring, the buildup is very thick and has no elasticity," said Kelly, 45, whose right elbow was most affected by the buildup of scar tissue. "The problem with thermal burn scarring [is that] it's hard to get the range of motion."

Kelly underwent numerous reparative surgeries through the years, but the scar tissue continued to grow back. The procedures did not lessen the look of her scars.

In 2011, Kelly underwent a new, experimental procedure that used stem cells from her own fat tissue to repair the buildup around her right elbow.

Surgeons cleaned the scar buildup around the elbow and used liposuction to pull fat from off Kelly's waist. They separated the fat cells from the stem and regenerative cells, which were then injected into the wound on Kelly's arm. The procedure took less than two hours.

Within months, Kelly was able to regain 40 degrees of motion that she had lost more than 40 years ago.

"If this technology was available earlier in my life, my scars would not have been as bad," said Kelly.

There are an estimated 50,000 to 70,000 burn cases each year in the U.S., according to the American Burn Association.

Houston Stem Cell Summit Announces Extraordinary Lineup of Keynote Speakers

The $700,000 study of the $3 billion
California stem cell agency is nearly concluded and is expected to be
released sometime in November.

“There will be no
further information-gathering meetings. The committee members have
finished drafting their report and it is now undergoing peer review.
Reviewers are anonymous to study staff and committee members; they
will be listed in the front matter of the report when it’s finished
and released.”

“Sponsors are not
treated as peer reviewers; that is, they’re not afforded an
opportunity to comment on IOM draft reports prior to public release.
IOM is aiming for a public release in November (the exact time frame
will hinge on the duration of the peer review, which is influenced by
people’s schedules and adherence to deadlines). IOM is looking at
options for how best to hold this release, whether there will be an
event of some sort. Once plans are set, they’ll be noted on the
project web pages and IOM will alert the various stakeholders and
interested parties of the plans. The study is moving along and we’re
looking forward to the report’s debut in the not too distant
future.”

California's $3 billion stem cell
research effort today garnered a handsome dollop of favorable
national news coverage– a lengthy piece in Fortune magazine that
spoke of looming stem cell cures and the leading role of the state
stem cell agency.

“The citizens of California have
spoken. If my grandmother and I had the power to get the rest of the
country to follow, we would.”

“To be clear, the earliest stem cell
therapies are almost certainly years from distribution. But so much
progress has been made at venerable research institutions that it now
seems possible to honestly discuss the possibility of a new medical
paradigm emerging within a generation. Working primarily with rodents
in preclinical trials, MDs and Ph.D.s are making the paralyzed walk
and the impotent virile. A stem cell therapy for two types of macular
degeneration recently restored the vision of two women. Once they
were blind. Now they see!

“Some experts assert that AMD could
be eradicated within a decade. Other scientists are heralding a
drug-free fix for HIV/AIDS. Various forms of cancer, Parkinson's,
diabetes, heart disease, stroke, and ALS have already been eradicated
in mice. If such work translates to humans, it will represent the
type of platform advancement that comes along in medicine only once
in a lifetime or two. The effect on the economy would be substantial.
Champions of stem cell research say it would be on the order of the
Internet or even the transistor.”

“The obstacles along the road from
lab rat to human patients are many, of course, but the biggest by far
is money. With the dramatic events in the lab, you might think that a
gold rush would be under way. That's far from true. Long time
horizons, regulatory hurdles, huge R&D costs, public sentiment,
and political headwinds have all scared financiers. Wall Street isn't
interested in financing this particular dream. Most stem cell
companies that have dared go public are trading down 90% or more from
their IPOs. Sand Hill Road is AWOL. The National Venture Capital
Association doesn't even have a category to track stem cell
investments.”

“The $1.7 billion awarded so far has made one obvious mark on the state: a dozen gleaming research institutions. CIRM has proved adept at getting billionaires to donate funds to the cause.”

“Goodness, you're talking to the
wrong guy. Our donation had nothing to do with business.”

“For close to two hours, Grove argues
passionately about how the FDA is enabling predatory offshore
industries by impeding progress and the many reasons financiers want
no part of stem cells. "VCs aren't interested because it's a
shitty business," he says. Big Pharma? Forget it. CIRM? "There
are gleaming fucking buildings everywhere. That wasn't necessary."
When I press him to be constructive, he wearily offers one possible
solution. Rather than courting billionaires to put their names on
buildings, we need a system of targeted philanthropy in which the 99%
can sponsor the individual stem cell lines that matter to them.”

“It was clear during our talk that
Grove wants an economic model for stem cell research and development
to emerge, even if he's not willing to bet money on its happening.
And that puts him in good company.”

One of the lesser known activities of
the California stem cell agency is webinars that put researchers
together with the folks who make the federal decisions about whether
stem cell research will be turned into therapies.

“The FDA very graciously donates
their time to speak on these webinars because they too have pledged
to maintain an active dialogue with the industry and provide
education on their regulatory expectations for product development in
the regenerative medicine field. CIRM science officer Kevin
Whittlesey recently
wrote a paper with Celia Witten of the FDA about the role of the
FDA in reaching out to regenerative medicine community, including
webinars such as these. 

“In that paper they point out that
the communication goes both ways:

“'Appropriate regulation requires a
strong understanding of the latest scientific developments to meet
current and future regulatory needs and challenges.'

“So the FDA benefits by learning from
the other speakers in the webinar – what is the current state of
the technology, what are investigator’s current thoughts on best
practices and the latest research findings, etc. They also learn what
the industry is facing by listening to the questions asked and the
discussion of the challenges during the Q&A sessions. A group of
FDA employees attend each of these CIRM sponsored webinars, and the
wide variety of other workshops and meetings that CIRM hosts
throughout the year.”

The Sacramento Bee today published an article that reported that $1.5 billion, more than 90 percent of the amount dispensed by the California stem cell agency, has gone to institutions linked to past and present directors of the agency.

The piece was carried on the front page of the newspaper's Sunday Forum section and was written by David Jensen, publisher-editor of the California Stem Cell Report.

The text of the Forum article is below. The Bee also carried a chart listing the top 10 recipient institution. The full text of the comments from Alan Trounson, president of the California stem cell agency,  and two other persons quoted in the article can be found here.

Stem cell cash mostly aids directors' interests

Here is the full text of comments made
by the California stem cell agency, Joe Mathews, co-author of
“California Crack-Up” and Bob Stern, former president of the
Center for Governmental Studies and co-author of the California
Political Reform Act, in connection with the Sept. 23, 2012, article
in The Sacramento Bee headlined “Stem Cell Cash Mostly Aids Directors' Interests.” The comments were abbreviated for
publication in The Bee because of newspaper space constraints.

“To make sure we do the best job of
managing taxpayer's money it's natural that we turn to people who
know most about stem cells and stem cell research. In fact, as the
state's own Little Hoover Commission reported in its analysis of
CIRM: “The fact that CIRM funding has gone largely to prestigious
California universities and research institutes is hardly surprising
and should be expected, given the goals of Proposition 71 and the
considerable expertise resident in these research centers.” But in
recruiting the best minds, we also adopt best practices to ensure
that there is no conflict of interest. Every board member has to
recuse themselves from voting on, or even being part of a discussion
on anything to do with their own institution, or to an institution or
company that they have any connections to. All this is done in
meetings that are open to the public. CIRM’s conflict of interest
rules have been subject to multiple reviews – by the Bureau of
State Audits, the Little Hoover Commission and the Controller – and
there is no evidence that any of CIRM’s funding decisions have been
driven by conflicts of interest. Indeed, CIRM rigorously enforces its
conflict of interest rules at each stage of the funding process to
ensure that all decisions are made on the merits of the proposal for
funding and not as a result of any conflicts of interest. 

“In addition all funding applications
are reviewed by an independent panel of scientists on our Grants
Working Groups, all of whom are out-of-state and meet strict conflict
of interest requirements, and it is their recommendations that help
guide the ICOC (CIRM governing board) on what to fund.”

“California ballot initiatives are a
terrible way to make public policy. And they are even worse as a
method for making scientific policy. 

“It's not merely that
this initiative was drafted in such a way as to benefit the
enterprises of its directors. It's that, under this initiative's own
provisions and the California constitution, it's so hard to change
Proposition 71 and fix what ails CIRM. Effectively, these provisions are
baked in, and nothing short of another vote of people can really make
the change. (Yes, there are provisions, as you know, that permit the
legislature by super-majority to do things, but supermajorities are
effectively out of reach in California). 

“Sadly, initiatives
like Proposition 71 are not uncommon. Many measures are drafted to benefit
the people who would support the measure, or oversee the program
established. This has been very common with bonds. Essentially, to
win the support of various groups whose money and backing is
important to passage of a bond, a sponsor of an initiative bond will
set up rules and include money specifically intended for each group.
This is a form of pay-to-play. Agree to back the initiative and
you're in. And it happens because there's no rule against it and
because passing initiatives in California require difficult,
expensive campaigns. 

“And this sort of thing will continue
to happen. There is no serious push to do anything about this.
Indeed, good government groups and reformers in California have
opposed changes to the initiative process -- because they want to use
the process for their own schemes.”

“It would have been better had
institutions receiving grants not to have had their representatives
on the board awarding grants. On the other hand, we want to have the
most knowledgeable people on the board overseeing this very important
program. The question: Were these people the only qualified ones to
sit on the board?”

Cytori Therapeutics Inc. (CYTX), a biotechnology company with $10 million in annual revenue, rose the most in more than a year after the company won a $4.7 million U.S. government contract to develop a stem cell therapy to treat burns caused by thermal or radioactive bombs.

Cytori jumped 19 percent to $4.58 at 12:11 p.m. New York time, after earlier reaching $4.93 for the biggest intraday increase since August 2011. The shares of the San Diego-based company rose 75 percent this year through yesterday.

Were seeing a lot of momentum, Chief Executive Officer Christopher Calhoun said today in an interview with Bloomberg Television. This contract is one more major thing that we are delivering on, and there is more to come. This is an important year for us.

The two-year contract with the Department of Health and Human Services Biomedical Advanced Research and Development Authority may be worth $106 million over five years if certain milestones are met, Cytori said today in a statement. The company had a net loss last year of $32 million, according to data compiled by Bloomberg.

Cytoris experimental therapy takes adipose tissue, or body fat, from a patient and through its device separates the adult stem and regenerative cells before transferring them to a burn wound. Money from the contract will be used to develop the device and take it through the U.S. regulatory approval process with the Food and Drug Administration, Calhoun said.

These cells help to facilitate the healing of the injury, he said in a telephone interview earlier this week. They release growth factors that stimulate new blood flow.

Testing the technology in a clinical trial and getting approval may take five years, Calhoun said. The company is currently testing its therapy for other soft tissue damage, as well as cardiovascular disease.

Once approved, the device will be deployed in hospitals across the country, and can be used for routine burns as well as a treatment for patients in wake of a mass casualty event that could injure 10,000 people, Cytori said in the statement.

ROCHESTER, Minn. -- Mayo Clinic researchers have found a way to detect and eliminate potentially troublemaking stem cells to make stem cell therapy safer. Induced Pluripotent Stem cells, also known as iPS cells, are bioengineered from adult tissues to have properties of embryonic stem cells, which have the unlimited capacity to differentiate and grow into any desired types of cells, such as skin, brain, lung and heart cells. However, during the differentiation process, some residual pluripotent or embryonic-like cells may remain and cause them to grow into tumors.

"Pluripotent stem cells show great promise in the field of regenerative medicine; however, the risk of uncontrolled cell growth will continue to prevent their use as a therapeutic treatment," says Timothy Nelson, Ph.D., M.D., lead author on the study, which appears in the October issue of STEM CELLS Translational Medicine.

Using mouse models, Mayo scientists overcame this drawback by pretreated stem cells with a chemotherapeutic agent that selectively damages the DNA of the stem cells, efficiently killing the tumor-forming cells. The contaminated cells died off, and the chemotherapy didn't affect the healthy cells, Dr. Nelson says.

"The goal of creating new therapies is twofold: to improve disease outcome with stem cell-based regenerative medicine while also ensuring safety. This research outlines a strategy to make stem cell therapies safer for our patients while preserving their therapeutic efficacy, thereby removing a barrier to translation of these treatments to the clinic," says co-author Alyson Smith, Ph.D.

Stem cell therapies continue to be refined and improved. Researchers are finding that stem cells may be more versatile than originally thought, which means they may be able to treat a wider variety of diseases, injuries and congenital anomalies. Stem cell therapy is an emerging regenerative strategy being studied at Mayo Clinic.

"By harnessing the potential of regenerative medicine, we'll be able to provide more definitive solutions to patients," says Andre Terzic, M.D., Ph.D., co-author and director of Mayo Clinic's Center for Regenerative Medicine.

Other members of the Mayo research team included Clifford Folmes, Ph.D., Katherine Hartjes, Natalie Nelson and Saji Oommen, Ph.D. The research was supported by the Todd and Karen Wanek Family Program for Hypoplastic Left Heart Syndrome, National Institutes of Health New Innovator Award OD007015-01, and a Mayo Clinic Center for Regenerative Medicine accelerated research grant.

Mayo Clinic finds way to weed out problem stem cells, making therapy safer

(WGBA/NBC) - It is a story that gives hope to pet owners all over the country stem cell therapy for animals suffering from problems like arthritis or hip displaysia.

Stem cells are taken out of the dog's fatty tissue are harvested then injected into problem areas leaving the dogs completely healed.

"We couldn't take him on walks, he just laid around a lot," said Keith Nosowiak, Deniro's owner.

"We'd hear whimpering overnight, she'd take a few steps and she would sit down," said Luther Kortbein, Shadow's owner.

Until two months ago, Deniro suffered from severe arthritis, Shadow from hip displaysia.

Deniro's owner thought he may even have to put his German shepherd down.

"We felt we had a decision to make with his quality of life and being in pain we didn't want him to be in pain," Noskowiak said.

Shadow's owner was willing to try anything to cure her.

"Whatever the cost needed to get this done we were willing to do," Kortbein said.

Then Packerland Veterinary Center offered them stem cell therapy by using the dogs own stem cells and then injecting them back into the bloodstream joints.

no easy task in trying to translate basic research findings into
something that can be used to treat patients and be sold commercially.

“One goal of scientific publication
is to share results in enough detail to allow other research teams to
reproduce them and build on them. However, many recent reports have
raised the alarm that a shocking amount of the published literature
in fields ranging from cancer biology to psychology is not
reproducible.”

“First, I think it is important to
accept that there is a crisis affecting preclinical research. Recent
studies estimate that 70% of preclinical research cannot be
reproduced. This is the research that should form the foundation upon
which new discoveries can be made to enhance health, lengthen life,
and reduce the burdens of illness and disability. The
irreproducibility of preclinical research is a significant impediment
to the achievement of these goals. To solve this problem requires
immediate and concrete action. It is not enough to make
recommendations and issue guidelines to researchers. Funders must act
to ensure they fund researchers to produce high quality reproducible
research. One such way to do so, is to reward, or require,
independent validation of results. The reproducibility initiative
provides a mechanism for independent validation, allowing the
identification of high quality reproducible research. It is vital
that funders act now to address this problem, to prevent the wasted
time and money that is currently spent funding non-reproducible
research and to prevent the erosion of public trust and support for
research.”
