New Fund Established to Stimulate Regenerative Medicine Industry

Fort Lauderdale, FL (PRWEB) April 29, 2012

Dr. Sassani states that he has been achieving significant and natural looking results with the addition of fat grafting with concentrated stem-cells to the list of services that he provides. The ideal candidate for this new innovative procedure has suffered a loss of volume of the face, which compromises skin texture. The skin may appear thinner lacking its once youthful volume.

Though injectables have their place in anti-aging, there is a significant difference between fat grafting with concentrated stem cells and all other injectible procedures. All injectables such as, Botox, Juvederm and Radiesse are composed of synthetic materials. In contrast, fat grafting with concentrated stem cell is completely natural because it is composed 100% of the individuals own fat cells. Fat grafting with concentrated stem cells offers something no other injectable can; use of the patients own tissue.

The fat is harvested from the lower abdomen and/or inner thighs to provide the volume necessary to correct the deficiency in the face. As an added bonus, the stem-cells that are transported along with the fat grafts are believed to improve overall skin color, texture and pore size. Stem cells are the repair cells of the body as they morph to become whatever cells they come in contact with. The harvested fat is spun in a centrifuge to concentrate these stem-cells for injection.

When should one have a facelift and when should you consider fat grafting with concentrated stem cells?

This procedure can be done either alone or in conjunction with facial aesthetic procedures. For patients exhibiting a loss of facial volume only, fat grafting with concentrated stem-cells done alone can be the ideal solution.

As the name suggests, facelifts lift sagging skin, tone the face and neck muscles, and remove the wrinkles. The ideal candidate for a facelift has suffered a loss of skin elasticity and muscle tone of the face and neck. Often the candidate will appear tired.

For candidates desiring a lift and tone of the face and neck with volume restoration, a facelift in combination with fat grafting may be the best solution. This candidate will have suffered a loss of skin elasticity, muscle tone and noticeable depletion of volume to the face.

The recovery time for all the procedures is approximately two weeks. After this time, the patient may comfortably return to normal social activities and interaction. A patients skin quality, texture, and tone will continue to improve as the stem-cells integrate. The end result is a tailored and youthful appearance with volume restoration and the skin noticeably improved overall. Patients will appreciate that the rejuvenative effects are enduring.

Fat Grafting with Concentrated Stemcells vs. Traditional Facelift

By Duke Medicine News and Communications

Scientists at Duke University Medical Center have shown the ability to turn scar tissue that forms after a heart attack into heart muscle cells using a new process that eliminates the need for stem cell transplant.

The study, published online April 26 in the journal Circulation Research, used molecules called microRNAs to trigger the cardiac tissue conversion in a lab dish and, for the first time, in a living mouse, demonstrating the potential of a simpler process for tissue regeneration.

If additional studies confirm the approach in human cells, it could lead to a new way for treating many of the 23 million people worldwide who suffer heart failure, which is often caused by scar tissue that develops after a heart attack. The approach could also have benefit beyond heart disease.

"This is a significant finding with many therapeutic implications," said Victor J. Dzau, MD, a senior author on the study who is James B. Duke professor of medicine and chancellor of health affairs at Duke University. "If you can do this in the heart, you can do it in the brain, the kidneys, and other tissues. This is a whole new way of regenerating tissue."

To initiate the regeneration, Dzau's team at Duke used microRNAs, which are molecules that serve as master regulators controlling the activity of multiple genes. Tailored in a specific combination, the microRNAs were delivered into scar tissue cells called fibroblasts, which develop after a heart attack and impair the organ's ability to pump blood.

Once deployed, the microRNAs reprogrammed fibroblasts to become cells resembling the cardiomyocytes that make up heart muscle. The Duke team not only proved this concept in the laboratory, but also demonstrated that the cell conversion could occur inside the body of a mouse -- a major requirement for regenerative medicine to become a potential therapy.

"This is one of the exciting things about our study," said Maria Mirotsou, PhD, assistant professor of cardiology at Duke and a senior author of the study. "We were able to achieve this tissue conversion in the heart with these microRNAs, which may be more practical for direct delivery into cells and allow for possible development of therapies without using genetic methods or transplantation of stem cells."

The researchers said using microRNA for tissue regeneration has several potential advantages over genetic methods or transplantation of stem cells, which have been difficult to manage inside the body. Notably, the microRNA process eliminates technical problems such as genetic alterations, while also avoiding the ethical dilemmas posed by stem cells.

"It's an exciting stage for reprogramming science," said Tilanthi M. Jayawardena, PhD, first author of the study. "It's a very young field, and we're all learning what it means to switch a cell's fate. We believe we've uncovered a way for it to be done, and that it has a lot of potential."

Duke Team Turns Scar Tissue into Heart Muscle Without Using Stem Cells

South San Francisco, CA (Marketwire) - VistaGen Therapeutics, Inc. (OTCBB: VSTA) (OTCQB: VSTA), a biotechnology company applying stem cell technology for drug rescue, has secured a new United States patent covering the company's proprietary methods used to measure and type the toxic effects produced by drug compounds in liver stem cells.

Test methods included in this new patent, (U.S. Patent 11/445,733), titled "Toxicity Typing Using Liver Stem Cells," cover all mammalian liver stem cells -- rat and mouse cells, for example, in addition to human cells. Liver stem cells used in drug testing can be derived from in vivo tissue or produced from embryonic stem cells (ES) or induced pluripotent stem cells (iPS).

H. Ralph Snodgrass, Ph.D., VistaGen's President and Chief Scientific Officer, said, "This patent covers the monitoring of changes in gene expression as an assay for predicting drug toxicities. It is well known that drugs activate and suppress specific genes, and that the changes in gene expression reflect the mechanism of drug toxicities. The specific sets of genes that are affected become a profile of that drug."

VistaGen's new patent also covers techniques used to develop a database of gene expression profiles of drugs that have the same type of liver toxicity. Using sophisticated "pattern matching" database tools, drug developers can analyze these related profiles to determine "gene expression signatures" that are common and predictive of drugs that produce specific types of toxicity.

"Without this database capability, a drug's single gene expression profile could not be interpreted," Dr. Snodgrass added. "The ability to use liver stem cells to differentiate drug-dependent gene expression profiles, and to compare those profiles of drugs known to induce toxic liver effects, provides a powerful tool for predicting liver toxicity of new drug candidates, including drug rescue variants."

Shawn K. Singh, VistaGen's Chief Executive Officer, stated, "Strong and enforceable intellectual property rights are critical components of our plan to optimize the commercial potential of our Human Clinical Trials in a Test Tube platform. This new liver toxicity typing patent further solidifies our growing IP portfolio, and supports the continuing development of LiverSafe 3D, our human liver cell-based bioassay system, which complements our CardioSafe 3D human heart cell-based bioassay system for heart toxicity."

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.
