Pet stem cells frozen and banked for future

ORLANDO, Fla. -

Eight Central Florida veterinary clinics are offering up a new procedure that could save or greatly improve a pet's life.

MediVet America has set up a holding center at the company's Nicholasville, Ken., lab to freeze and store pet stem cells for future use.  Clinical studies have shown the cells can be viable for decades.

The procedure extracts stem cells from the animal's own fat tissue. The cells are then treated and used for aging dogs and cats struggling with arthritis or degenerative disease for several years, with good results.

By "cryobanking," the healthy cells, they will be ready if needed in the future.

"Banking stem cells is like having an extra insurance policy for your pet," explained Jeremy Delk, CEO of MediVet America.

Dr. Daniel Evers of ValuVet is taking part in a pet stem cell project in Central Florida to determine if the stem cells are actually causing cartilage regeneration.

Twelve pets will be selected for the study, which will include two separate MRI scans to determine how effective the stem cell treatments are for pets struggling with joint issues.

Normally, the initial cost is $420, with a $150 annual storage fee. Owners whose pets are selected will get a discount on the stem cell procedure. Pet owners interested in the procedure can contact Erica Kent at erica@medivet-america.com or call 386-748-4251.

Editor’s move sparks backlash

Posted: February 22, 2012 at 3:28 am

Bioethicist Glenn McGee’s new job raised questions of conflict of interest at the journal he founded.

J. WILSON/KRT/NEWSCOM

The field of bioethics is embroiled in a period of soul-searching, sparked by a startling career move by one of its biggest names.

Glenn McGee is the editor-in-chief of the American Journal of Bioethics (AJOB), the most cited bioethics journal, which he founded in 1999. Since December 2011, he has also been president for ethics and strategic initiatives at CellTex Therapeutics in Houston, Texas, a controversial company involved in providing customers with unproven stem-cell therapies. A CellTex press release says that “Dr McGee’s responsibilities will include ensuring that all of the firm’s work, centered on adult stem cells, will meet the highest ethical standards of the medical and scientific communities.”

Although McGee has said he will leave the journal on 1 March, many bioethicists have criticized him, the journal’s editorial board and its publisher, London-based Taylor and Francis. They argue that in holding both posts, McGee has a conflict of interest between his responsibilities to the journal and his new employer’s desire to promote the clinical application of stem-cell treatments that are not approved by the US Food and Drug Administration.

“Imagine if the Editor of the New England Journal of Medicine took a job as Vice President at Merck, and the Mass Medical Society asked him to stay on as Editor, opining that the conflicts of interest would be manageable. One might rightly wonder, ‘What are these people smoking?’,” says John Lantos, director of the Children’s Mercy Bioethics Center in Kansas City, Missouri, and a past president of the American Society for Bioethics and Humanities.

More broadly, bioethicists are questioning whether it can ever be acceptable to work for companies, which, they argue, may be using the appointment to present a veneer of ethical probity. The episode brings to a head concerns that have emerged among bioethicists over the past decade, says Insoo Hyun, a stem-cell bioethicist at Case Western Reserve University in Cleveland, Ohio. “It’s a perfect storm,” he says.

McGee is a leading voice on one side of the debate, arguing that bioethics must have practical relevance. For the past three years he has been chair of bioethics at the non-profit Center for Practical Bioethics in Kansas City, where he ran a course for those who might go on to chair hospital ethics committees or serve as ethical advisers to corporations.

But during McGee’s tenure as editor-in-chief of the AJOB, four editors are known to have resigned from the editorial board because of differences in opinion over how the journal handles conflicts of interest. Two left this month, including Lantos, who wrote on his blog that he will no longer work with the journal because of McGee’s simultaneous employment at the AJOB and CellTex, and frustration over the lack of a clear conflict-of-interest policy at the AJOB. In response to Nature’s questions about the situation, Taylor and Francis responded that it “is grateful for Dr McGee’s editorship of AJOB” and “supportive of Glenn’s decision to step down”.

On 17 February, McGee announced that he is merely acting in an advisory capacity at the journal until 1 March, when its new editors-in-chief take over. They are David Magnus, director of the Center for Biomedical Ethics at Stanford University, California, and Summer Johnson McGee, director of graduate studies at the Center for Practical Bioethics and the journal’s current executive editor. She is also Glenn McGee’s wife.

“Mainstream bioethics is no longer speaking truth to power.”

Responding to questions from Nature, Summer Johnson McGee says that the journal has a conflict-of-interest policy that requires editors to withdraw from reviewing a manuscript if they perceive a conflict. She calls allegations that her appointment results from her relationship with her husband “baseless and sexist”. “David Magnus and I were hired by our publisher, not by my husband.” Magnus says that at least a dozen editorial board members have supported his and Summer Johnson McGee’s appointments. Two even indicated that Glenn McGee should have been able to retain an advisory or editorial role.

Other bioethicists’ blogs and Twitter feeds about the episode have expressed concerns, however. Leigh Turner of the University of Minnesota, Minneapolis, called on the entire editorial board of the AJOB to resign for allowing the situation to persist. And many say that McGee’s move illustrates a broader problem. “Mainstream bioethics is no longer speaking truth to power,” complains Jan Helge Solbakk at the University of Oslo. “Instead it has become the handmaiden of the medico-industrial complex, and of bioscience and technology.”

So how should companies get their advice on bioethics? Magnus never takes cash from industry for advising or speaking — “I’m a hardass about that” — but he believes that bioethicists can work for industry as long as they give up their academic positions, including posts on journal editorial boards.

Working for a respected company may be acceptable to some bioethicists, but McGee’s new employer comes with a great deal of baggage. CellTex, which was founded last year and as yet has no website, licenses stem-cell technology from Seoul-based RNL Bio. The South Korean company has made a business out of taking fat cells from people, processing them in a way that they say increases the number of mesenchymal stem cells, and then reinjecting them in an effort to treat conditions such as spinal cord injury.

McGee already had a connection with RNL Bio. In 2010, two patients died following injections of RNL’s cells. McGee, working for stem-cell lobby group the International Cellular Medicine Society, based in Salem, Oregon, helped to conduct an investigation into the company. This concluded that only one of the two cases was likely to be related to the injections, and because the patient understood the risk the company was not culpable.

Jin Han Hong, the then president of RNL’s US subsidiary, admitted in 2010 that there was no clinical-trial evidence proving that these treatments are effective (Nature 468, 485; 2010). As treatment with RNL’s stem cells is not approved in the United States or South Korea, for the procedures the company sends patients to China or Japan, where regulations are less strictly enforced. Using RNL’s methods, CellTex is banking stem cells that have gone on to be used in a number of patients, including Rick Perry, governor of Texas (Nature 477, 377–378; 2011). CellTex says that it does not conduct medical procedures itself.

When Nature contacted McGee to put the criticisms to him, he directed us to previous statements indicating that he wants to put CellTex on firmer ethical ground by having it conduct clinical trials that meet standards set by the International Society for Stem Cell Research, based in Deerfield, Illinois, which represents most mainstream stem-cell researchers around the world.

Hyun warns that working directly for business can be fraught with danger, however good a bioethicist’s intentions. In 2005, he helped to craft the informed consent procedure for egg donations used in a cloning procedure by disgraced Korean stem-cell scientist Woo Suk Hwang. Following Hwang’s claim, later proved fraudulent, that he had cloned human embryos and harvested stem cells from them, it emerged that he had ignored the consent procedure for egg donations (Nature 438, 536–537; 2005), leading to embarrassment for Hyun.

“I know first hand how difficult it is to separate conflict of interest — to maintain the role of bioethicist,” says Hyun. “I know you need to not be too chummy with enterprises trying to speed ahead in stem cells.”

Sigma® Life Science Obtains Global License for Kyoto University's iPS Cell Patent Portfolio, Deepens Commitment to …

Posted: February 22, 2012 at 3:28 am

 

 

ST. LOUIS, Mo., Feb. 21, 2012 /PRNewswire/ -- Sigma-Aldrich Corporation (Nasdaq: SIAL) today announced that Sigma Life Science, its innovative biological products and services research business, has furthered its commitment to stem cell research, drug discovery and ADME/Toxicology by acquiring a worldwide license to use Kyoto University's induced pluripotent stem (iPS) cell patent portfolio. Sigma Life Science, leveraging its zinc finger protein platform and stem cell technology portfolio, is now poised to develop a new set of differentiated tools for both the drug discovery and preclinical research communities. These tools will include novel iPS-cells, iPS-cell derived primary cells, novel assays, custom cell line development and ADME/Toxicology services.  Under the terms of the agreement, iPS Academia Japan, Inc. (AJ) will receive a license fee from Sigma-Aldrich.

iPS cell technology can create pluripotent stem cells from the normal adult cells of a patient. Pluripotent stem cells are capable of differentiating into many specialized primary cell types needed for research, such as cardiomyocytes, hepatocytes, neurons, and muscle cells. With access to differentiated cells from patients with the condition of interest, or healthy human cells engineered to contain disease-specific genetics, researchers may obtain greater predictive accuracy than is possible with the in vitro models used currently in pharmaceutical research and preclinical studies.

"The pace of progress in iPS cell research has been breathtaking thanks to many scientists' strenuous efforts. With the non-exclusive license agreement that has been formed by Sigma-Aldrich, a global corporation in the life science field, and iPS Academia Japan, I expect that this move will further accelerate research and development using iPS cell technologies not only in the United States but also in the rest of the world," said Professor Shinya Yamanaka, Director of the Center for iPS Cell Research and Application (CiRA) at Kyoto University.

"Our license with Kyoto University grants us the freedom to operate under Kyoto University's induced pluripotent stem (iPS) cell patent portfolio in the increasingly important field of stem-cell based research and development. Researchers currently use primary cells derived from techniques that lack consistency and the ability to genetically engineer cells. Using the Kyoto iPS cell technology and our zinc finger protein technologies, we hope to generate stable, defined sets of cells and subsequently derived tissues whose predictive power will allow us to develop a new paradigm in assay development," says David Smoller, Ph.D., Chief Scientific Officer at Sigma-Aldrich. "Thus, our Sigma-Aldrich scientists may be able to guide cells through the critical series of maturation steps — in ways no one has done previously — and also add reporter genes into these cells so that researchers can directly visualize the true biology of cellular processes."

Sigma Life Science's new iPS cell-based technologies, along with its existing stem cell product portfolio of serum-free cell culture products, cell culture media, 3D matrices, growth factors, and antibodies, will provide uniquely comprehensive support for iPS cell-related research.

Qatari students to present research on stem cells

Posted: February 22, 2012 at 3:28 am

Research on the potential of stem cells in preventing ovarian cancer, obesity-related diseases and other serious illnesses affecting people in Qatar and the region is to be presented by three Qatari graduate students at the Qatar International Conference on Stem Cell Science and Policy next week.
The conference is organised by Qatar Foundation for Education, Science and Community Development (QF) and James A Baker III Institute for Public Policy.
It will provide an international platform to discuss the latest discoveries in stem cell research and collaborate on new therapeutic approaches for the use of stem cells, within an acceptable ethics, cultural and religious framework.
The students are part of QF’s Qatar Science Leadership Programme (QSLP), and their participation in the conference is considered an important part of their training. 
With more than 400 registered participants, including key ethicists and scientists in stem cell research, the conference provides students invaluable opportunities for exchanging knowledge and building relationships with top figures and leading regional and international institutions in the field.
QSLP, aims to equip rising Qatari generations for leading roles in the country’s scientific and research endeavours, with stem cell research as a national priority.
Qatari QSLP trainee and PhD student from Paris XI University, Dr Hamda al-Thawadi, will present at the conference a poster about her research on ovarian cancer.
She explained that this is an important area specifically for Qatar, as there is a high prevalence of thrombotic diseases which affect patients with cancer.
“My project will help in detecting a powerful tool for the assessment of thrombosis risk factors in patients with cancer as well as healthy individuals, which should help develop preventative measures,” she said.
Dr Halema Alfarsi, another student on QSLP’s scientific track, is also presenting her research on ovarian cancer at the conference. Her work explores the potential application of stem cells in making cells and tissues for medical therapies.
She pointed out that currently, donated tissues and organs are often used to replace those that are diseased or destroyed. Stem cells offer a viable source of replacement cells to treat diseases and can potentially reduce the morbidity and mortality for those awaiting transplants for Parkinson’s disease, spinal cord injury, severe burns, diabetes and arthritis.
“In Qatar we have many cases of cancer, diabetes, heart disease and arthritis. Stem cells offer hope for effective treatment or perhaps even reversal of the disease,” added Dr Alfarsi.
The recently published Heba al-Siddiqi, another QSLP student, will present her research on preventing chronic obesity-related diseases through tissue engineering and organ regeneration. This research was recently featured in the leading international scientific journal Nature.
“Tackling obesity-related diseases such as coronary heart disease and type 2 diabetes through developing stem cell technology is very important as these diseases are increasingly common in Qatar,” observed al-Siddiqi.
“I am excited about the potential of creating cell-based therapies to treat and prevent chronic diseases in Qatar for future generations,” she added.
The three student presenters will be joined at the conference by their fellow QSLP members, Sarah Ali Abdulla and Abeer al-Shammari. 
Abdulla, who is pursuing her PhD in stem cell science and neuroscience at the University of Cambridge, will serve as master of ceremonies over the conference’s four days.
“The Qatar conference on stem cells supports our students’ scientific development by including them in the country’s stem cell research community and connecting them with leading figures in the field. We hope it will inspire young people in Qatar and the region to pursue studies in stem cell science,” said QF’s head of Research Training and Development, Dr Ayman Bassil.
The Qatar International Conference on Stem Cell Science and Policy opens on February 27, 2012 at the Qatar National Convention Centre.

Pathfinder Presents Preliminary Data on New Regenerative Approach to Diabetes Treatment

Posted: February 21, 2012 at 9:51 pm

CAMBRIDGE, Mass., Feb. 21, 2012 (GLOBE NEWSWIRE) -- Pathfinder Cell Therapy, Inc. ("Pathfinder," or "the Company") (OTCQB:PFND.PK - News), a biotechnology company focused on the treatment of diabetes and other diseases characterized by organ-specific cell damage, today presented preliminary data highlighting the potential of the Company's unique cell-based therapy for treating diabetes at the 7th Annual New York Stem Cell Summit. Richard L. Franklin, M.D., Ph.D., Founder, CEO and President of Pathfinder, provided an overview of the Company's Pathfinder Cell ("PC") technology, and presented preclinical evidence demonstrating how treatment with PCs was able to reverse the symptoms of diabetes in two different mouse models.

Pathfinder Cells are a newly identified non-stem cell mammalian cell type that has the ability to stimulate regeneration of damaged tissue without being incorporated into the new tissue. In today's presentation, Dr. Franklin showed how recent experiments performed using a non-obese diabetic (NOD) mouse strain were supportive of earlier data that demonstrated complete reversal of diabetes in mice. The earlier results, which used a drug-induced diabetic mouse model, were published in Rejuvenation Research1. Though preliminary, the recent results are encouraging because the NOD mouse model is widely used and highly regarded as being predictive of human type-1 diabetes.

In three separate experiments using this model, 30-50% of the mice treated with PCs at the onset of diabetes returned to normal blood glucose levels. Of the mice that responded well to treatment, the effects tended to be long lasting, up to two months in some cases after just two doses. These results, which were generated by intravenous injection of PC's derived from rat pancreatic tissue, further demonstrate the remarkable ability of Pathfinder Cells to elicit their positive effect regardless of the organ, or even species, of origin.

"We are very encouraged by these preclinical results using NOD mice. This model is the gold standard for type-1 diabetes and the fact that recent experiments mirror what we've seen in previous models may be highly significant," stated Dr. Franklin. "We have many questions to answer about how PCs act in the body, but we believe, based on previous experiments, that PCs may stimulate regeneration of damaged islet cells that produce insulin. The current NOD mouse data also suggest that PCs may have an effect in modulating the auto-immune process in type 1 diabetes. We continue to conduct experiments aimed at elucidating the optimal dosing and other factors that may be responsible for producing a robust and long-lasting response, as this will be critical as we start to think about how PCs may be used in treating human diabetes."

In his presentation today, Dr. Franklin also provided further insight into the mechanism of action of PCs, based on recent animal experiments. It was observed previously that PCs produce microvesicles, which are known to play a role in intercellular communication, but through mechanisms that are poorly understood. In a recent experiment, Pathfinder was able to isolate these microvesicles from the PCs and treat animals directly with an injection containing microvesicles only. Remarkably, both PC- and microvesicle-treated mice exhibited similar reductions in blood glucose compared to controls using the same drug-induced diabetes mouse model. This suggests, not only that the microvesicles produced by PCs are central to the mechanism of action, but that the microvesicles alone appear to be sufficient to produce the full effect.

Dr. Franklin commented, "If confirmed, this finding could have a significant positive impact on the future of PC-based therapy. Due to the relatively small amount of material contained within the microvesicles, determining the specific factor(s) that are responsible for regenerating damaged tissue could be more straightforward than we first anticipated, bringing us closer to understanding the mechanism of action. There may also be a number of potential manufacturing and storage benefits to using microvesicles versus PCs that will be interesting to explore in parallel as we work to advance this innovative new therapeutic approach closer to human clinical development."

The New York Stem Cell Summit brings together cell therapy company executives, researchers, investors and physicians to explore investment opportunities in cell therapy research and innovation. More information can be found at http://www.stemcellsummit.com.

Presentation details Event: 7th Annual New York Stem Cell Summit Date: Tuesday, February 21, 2012 Place: Bridgewaters New York, 11 Fulton Street, New York, NY Time: 3:35 pm ET

About Pathfinder

Pathfinder is developing a novel cell-based therapy and has generated encouraging preclinical data in models of diabetes, renal disease, myocardial infarction, and critical limb ischemia, a severe form of peripheral vascular disease. Leveraging its internal discovery of Pathfinder Cells ("PCs") Pathfinder is pioneering a new field in regenerative medicine.

PCs are a newly identified mammalian cell type present in very low quantities in a variety of organs, including the kidney, liver, pancreas, lymph nodes, myometrium, bone marrow and blood. Early studies indicate that PCs stimulate regeneration of damaged tissues without the cells themselves being incorporated into the newly generated tissue. Based on testing to date, the cells appear to be "immune privileged," and their effects appear to be independent of the tissue source of PCs.

Stem Cell Study Finds New Treatments For Breast Cancer – Video

Posted: February 21, 2012 at 8:13 pm

06-02-2012 16:47 Salk scientists use an old theory to discover new targets in the fight against breast cancer Similarities between genetic signatures in developing organs and breast cancer could predict and personalize cancer therapies Reviving a theory first proposed in the late 1800s that the development of organs in the normal embryo and the development of cancers are related, scientists at the Salk Institute for Biological Studies have studied organ development in mice to unravel how breast cancers, and perhaps other cancers, develop in people. Their findings provide new ways to predict and personalize the diagnosis and treatment of cancer. In a paper published February 3 in Cell Stem Cell, the scientists report striking similarities between genetic signatures found in certain types of human breast cancer and those of stem cells in breast tissue in mouse embryos. These findings suggest that cancer cells subvert key genetic programs that guide immature cells to build organs during normal growth. "Stem cells in a healthy developing embryo have a GPS system to alert them about their position in the organ," says Geoffrey Wahl, a professor in Salk's Gene Expression Laboratory, who led the research. "The system depends on internal instructions and external signals from the environment to tell the stem cell what to do and where to go in the body. It stimulates the stem cells to grow and form more stem cells, or to change into different cells that form complex organs, such as the breast. Our ...

Also the way itself we face the problem of sickness, aging and death changes as the hope (or the illusion?) grows that we always can fight and delay them. Stem cell research is in fact changing our knowledge of the fundamental mechanisms of life and feeding the idea that we can increasingly contrast the cruel natural selection rules which make us fall ill, grow old and die. A new frontier opens and unpredictable changes in our culture are taking place. People's hopes and fears grow at the same time. The general properties of the stem cells is presented, namely the ability to proliferate and, under certain conditions, to differentiate in other types of cells. In this way they can generate a new tissue replacing a damaged one, and also a new organ (like blood, thrachea, liver, heart, skin, cornea and very recently retina). A stamp is shown, which was emitted by the Japanese government to celebrate the discovery of a university team, which was able to regenerate a cornea and giving the opportunity to a patient to see again. Then the innovative results is presented in applications of the stem cells to orthopedy, muscular dystrophy, cardiology and dentistry. Finally the etherogeneus perspectives is presented offered by stem cell research to treat degenerative disorders, like Alzheimer, Parkinson diseases and Multiple Sclerosis. www ...
