Veterinarians hope a new medical procedure can treat a 25-year-old chimpanzee with a torn ACL, or anterior cruciate ligament, at the "Save the Chimps" in Florida.

The procedure involves injecting the chimp with her own stem cells.

"With chimps we don't want to do a lot of surgical work, put hardware in their knee, they tend to pull out that sort of thing," said Veterinarian Linda Gregard, M.D.

Dr. Darrell Nazareth with the Florida Veterinary League has been using stem cells to treat dogs with arthritis for the past two years, but this is his first chimp.

"We're not using embryonic stem cells, we're not taking embryos and taking their stem cells from there. We're just using the patient's own tissue," said Dr. Nazareth.

The technology harnesses the bodies own ability to heal itself and doctors hope it could find wider use in humans.

After injecting two billion stem cells into Angie's knee, doctors will find out in the next two to three weeks if the stem cell therapy treatment was successful.

PORTLAND, Ore. Multiple myeloma patients are better equipped to halt progression of this blood cancer if treated with lenalidomide, or Revlimid, following a stem cell transplant, according to a study co-authored by a physician with the Oregon Health & Science University Knight Cancer Institute.

The study, published in the New England Journal of Medicine, found a 63 percent reduction in the risk of progressive myeloma or death for the stem cell transplant patients that were treated with lenalidomide maintenance therapy.

"These results add to the evidence that the combination of standard therapies such as stem cell transplantation with the emerging biologic therapies, like lenalidomide, have extended the lives of multiple myeloma patients," said Richard Maziarz, M.D., of the OHSU Knight Cancer Institute who was one of the study's co-authors. Maziarz serves as medical director of the Adult Stem Cell Transplantation Program & Center for Hematologic Malignancies at the OHSU Knight Cancer Institute. "We know that for at least three years following a transplant that maintenance therapy with this drug vastly improves the chances that the cancer won't come back and worsen."

These data were supported by similar Phase III studies reported from France and Italy in the same issue of the New England Jounal of Medicine demonstrating that maintenance therapy after stem cell transplantation was associated with improved disease control.

Multiple myeloma is a cancer that affects plasma cells, a type of white blood cell normally responsible for producing antibodies. In patients impacted by multiple myeloma, collections of abnormal plasma cells accumulate in the bone marrow, interfering with the production of normal blood cells. The study focused on patients who received an autologous hematopoietic cell transplant (AHCT). AHCT procedures use patients' own blood stem cells.

While lenalidomide increased a patient's ability to stave off progression of the disease, questions remain regarding future approaches recognizing that quality of life measurements were not incorporated within these studies, that long-term safety issues remain unclear as there was a small but discernable risk of second cancers observed in the treated patients. In addition to the need for that cost-benefit analysis, a comparison remains to be performed with other emerging myeloma maintenance therapies.

This Phase III study of lenalidomide was conducted at 47 medical centers and involved 568 patients. It was sponsored by the National Cancer Institute (NCI). Revlimid's manufacturer, Celgene Corp., provided the NCI with lenalidomide for this research.

Tampa, Fla. (May. 8, 2012) Two studies appearing in a recent issue of Cell Transplantation (20:11-12), now freely available on-line at http://www.ingentaconnect.com/content/cog/ct/, evaluate stem cells derived from dental tissues for characteristics that may make them therapeutically useful and appropriate for transplantation purposes.

Induced pluripotent stem cells from immature dental pulp stem cells

A Brazilian and American team of researchers used human immature dental pulp stem cells (IDPSCs) as an alternative source for creating induced pluripotent stem cells (iPSCs), stem cells that can be derived from several kinds of adult tissues. According to the study authors, production of iPSCs "opens new opportunities for increased understanding of human genetic diseases and embryogenesis" and will likely have a "great impact on future drug screening and toxicology tests."

The authors note, however, that the reprogramming methodology for making iPSCs is relatively new and "needs refining" in terms of technique, efficiency and cell type choice.

The researchers report that they easily, and in a short time frame, programmed human immature dental pulp stem cells into iPSCs with the hallmarks of pluripotent stem cells.

"Human IDPSCs can be easily derived from dental pulp extracted from adult or 'baby teeth' during routine dental visits," said study lead author Dr. Patricia C.B. Beltrao-Braga of the highly ranked National Institute of Science and Technology in Stem and Cell Therapy in Ribeirao Preto, Brazil. "hIDPSCs are immunologically privileged and can be used in the absence of any immune suppression protocol and have valuable cell therapy applications, including reconstruction of large cranial defects."

2 Cell Transplantation studies impact dental stem cell research for therapeutic purposes

(SACRAMENTO, Calif.) -- UC Davis Health System researchers are a step closer to launching human clinical trials involving the use of an innovative stem cell therapy to fight the virus that causes AIDS.

In a paper published in the May issue of the Journal of Virology, the UC Davis HIV team demonstrated both the safety and efficacy of transplanting anti-HIV stem cells into mice that represent models of infected patients. The technique, which involves replacing the immune system with stem cells engineered with a triple combination of HIV-resistant genes, proved capable of replicating a normally functioning human immune system by protecting and expanding HIV-resistant immune cells. The cells thrived and self-renewed even when challenged with an HIV viral load.

"We envision this as a potential functional cure for patients infected with HIV, giving them the ability to maintain a normal immune system through genetic resistance," said lead author Joseph Anderson, an assistant adjunct professor of internal medicine and a stem cell researcher at the UC Davis Institute for Regenerative Cures. "Ideally, it would be a one-time treatment through which stem cells express HIV-resistant genes, which in turn generate an entire HIV-resistant immune system."

To establish immunity in mice whose immune systems paralleled those of patients with HIV, Anderson and his team genetically modified human blood stem cells, which are responsible for producing the various types of immune cells in the body.

Building on work that members of the team have pursued over the last decade, they developed several anti-HIV genes that were inserted into blood stem cells using standard gene-therapy techniques and viral vectors (viruses that efficiently insert the genes they carry into host cells). The resulting combination vector contained:

These engineered blood stem cells, which could be differentiated into normal and functional human immune cells, were introduced into the mice. The goal was to validate whether this experimental treatment would result in an immune system that remained functional, even in the face of an HIV infection, and would halt or slow the progression toward AIDS.

The results were successful on all counts.

"After we challenged transplanted mice with live HIV, we demonstrated that the cells with HIV-resistant genes were protected from infection and survived in the face of a viral challenge, maintaining normal human CD4 levels," said Anderson. CD4+ T-cells are a type of specialized immune cell that HIV attacks and uses to make more copies of HIV.

"We actually saw an expansion of resistant cells after the viral challenge, because other cells which were not resistant were being killed off, and only the resistant cells remained, which took over the immune system and maintained normal CD4 levels," added Anderson.

The data provided from the study confirm the safety and efficacy of this combination anti-HIV lentiviral vector in a hematopoietic stem cell gene therapy setting for HIV and validated its potential application in future human clinical trials. The team has submitted a grant application for human clinical trials and is currently seeking regulatory approval, which is necessary to move on to clinical trials.

Juvenile Parkinson's - Stem cell therapy - Video

South San Francisco, CA (Marketwire) - VistaGen Therapeutics, Inc. (OTCBB:VSTA) (OTCQB:VSTA), a biotechnology company applying stem cell technology for drug rescue and cell therapy, has licensed breakthrough stem cell culture technology from the McEwen Centre for Regenerative Medicine located at the University Health Network (UHN) in Toronto, Canada.

VistaGen will be utilizing the licensed technology to develop hematopoietic precursor stem cells from human pluripotent stem cells, with the goal of developing drug screening and cell therapy applications for human blood system disorders. The breakthrough technology is included in a new United States patent application.

Hematopoietic precursor stem cells give rise to all red and white blood cells and platelets in the body. VistaGen will use the UHN invention to improve the cell culture methods used to efficiently produce hematopoietic stem cell populations.

"This technology dramatically advances our ability to produce and purify this important blood stem cell precursor for both in vitro drug screening and in vivo cell therapy applications," said H. Ralph Snodgrass, PhD, VistaGen's President and Chief Scientific Officer.

"In addition to defining new cell culture methods for our use, the technology describes the surface characteristics of stem cell-derived adult hematopoietic stem cells. Most groups study embryonic blood development from stem cells, but, for the first time, we are able to not only purify the stem cell-derived precursor of all adult hematopoietic cells, but also pinpoint the precise timing when adult blood cell differentiation takes place in these cultures," Snodgrass added. "It is our belief that these early cells will be the precursors of the ultimate adult, bone marrow-repopulating hematopoietic stem cells."

Bone marrow-derived hematopoietic stem cells are able to repopulate the blood and immune system when transplanted into patients prepared for bone marrow transplantation. These cells have important potential therapeutic applications for the restoration of healthy blood and immune systems in individuals undergoing transplantation therapies for cancer, organ grafts, HIV infections or for acquired or genetic blood and immune deficiencies.

About VistaGen Therapeutics VistaGen is a biotechnology company applying human pluripotent stem cell technology for drug rescue and cell therapy. VistaGen's drug rescue activities combine its human pluripotent stem cell technology platform, Human Clinical Trials in a Test Tube, with modern medicinal chemistry to generate new chemical variants (Drug Rescue Variants) of once-promising small-molecule drug candidates. These are drug candidates discontinued due to heart toxicity after substantial development by pharmaceutical companies, the U.S. National Institutes of Health (NIH) or university laboratories. VistaGen uses its pluripotent stem cell technology to generate early indications, or predictions, of how humans will ultimately respond to new drug candidates before they are ever tested in humans, bringing human biology to the front end of the drug development process.

Additionally, VistaGen's small molecule drug candidate, AV-101, is in Phase 1b development for treatment of neuropathic pain. Neuropathic pain, a serious and chronic condition causing pain after an injury or disease of the peripheral or central nervous system, affects approximately 1.8 million people in the U.S. alone. VistaGen is also exploring opportunities to leverage its current Phase 1 clinical program to enable additional Phase 2 clinical studies of AV-101 for epilepsy, Parkinson's disease and depression. To date, VistaGen has been awarded over $8.5 million from the NIH for development of AV-101.

Stem Cell Therapy for Stroke - Video

When Tyler was born, the umbilical cord was wrapped around his neck, causing a lack of oxygen to his brain that led to Tyler suffering a stroke during delivery. The stroke caused damage to the back of Tylers brain. Tyler was diagnosed with cerebral palsy and his mother, Lisa Biermann, was told to expect the worst: a child who would never walk, talk, or have any chance at a normal life.

Lisa refused to give up hope. She tried everything she could to help Tyler. Tyler could not walk because his feet would not sit flat on the floor. She tried botox injections every three months, braces, casts and even ankle cord surgery. Nothing worked.

Lisa said Tyler could not communicate with her at all. She never knew when he was in pain because he was unable to tell her.

Tyler was considered to be blind, with a prescription that was over nine units nearsighted, and his eyes jumped around. Even with glasses, he could not focus his vision, and doctors did not believe he could see, or ever would see.

Until he was 8 years old, Lisa would carry Tyler from his classes at Woodland Park Elementary.

When Tyler was 8, he had a seizure. Dr. David Steenblock, who is based in California, heard about Tyler and offered to help him with umbilical cord stem cell therapy. Lisa said she thought hard about it, and because she had tried everything else and nothing had worked, she decided to try the stem cell therapy, which Dr. Steenblock told her had no side effects.

In December 2007, Lisa, Dr. Steenblock and his team took Tyler for the treatment, which had to be done in Tijuana, Mexico, because stem cells injection is currently not legal in the United States. Three months later, they went for a second injection.

The stem cells were given to Tyler intravenously for a period of approximately 45 minutes.

Lisa said within weeks, she saw monumental changes in Tyler. All the milestones he never reached as a baby, he began reaching.

Within three months Tyler could put his feet flat on the floor and could walk independently. At six months post-treatment, he no longer needed the painful braces that gave him bunions.
