Heart-Attack Damage Heals After Stem Cell Treatment Feb. 13, 2012 -- A new stem cell treatment resurrects dead, scarred heart muscle damaged by a recent heart attack. The finding, just in time for Valentine's Day, is the clearest evidence yet that literally broken hearts can heal. All that's needed is a little help from one's own heart stem cells. "We have been trying as doctors for centuries to find a treatment that actually reverses heart injury," Eduardo Marban, MD, PhD, tells WebMD. "That is what we seem to have been able to achieve in this small number of patients. If so, this could change the nature of medicine. We could go to the root of disease and cure it instead of just work around it." Marban, director of the Cedars-Sinai Heart Institute in Los Angeles, led the study. He invented the "cardiosphere" culture technique used to create the stem cells and founded the company developing the treatment. It's the first completed, controlled clinical trial showing that scarred heart tissue can be repaired. Earlier work in patients with heart failure, using different stem cells or bone-marrow stem cells, also showed that the heart can regenerate itself. "These findings suggest that this … Continue reading →

WALKER, Mich. (WOOD) - Dogs who received the first in-clinic stem cell therapy in West Michigan returned to the vets who treated them Monday morning. Boris and Natasha returned to Kelley's Animal Clinic for their 60-day checkup after receiving stem cell treatment in December 2011. Dr. James Kelley and his staff of vets removed fat tissue from the dogs and activated it with an enzyme before injecting it into their back legs. This adult animal stem cell technology is different from the controversial embryonic stem cell therapy. Kelley said both dogs are doing amazingly well and that the procedure has done more than just help their arthritis. "We're finding that not only the joints are affected, the rest of the animal is affected as well," said Kelley. "The skin is better. The attitude in these dogs is much improved." Kelley and his staff have done 16 stem cell treatments since the first on Boris and Natasha, and he said all the dogs are showing signs of improvement after a short period of time.

A promising stem cell therapy approach could soon provide a way to regenerate heart muscle damaged by heart attacks. Researchers at Cedars-Sinai Heart Institute and The Johns Hopkins University harvested stem cells from the hearts of 17 heart attack patients and after prepping the cells, infused them back into the patients' hearts. Their study is published in the current issue of The Lancet. The patients received the stem cell infusions about three months after their heart attacks. Researchers found that six months after treatment, patients had significantly less scarring of the heart muscle and also showed a considerable increase the amount of healthy heart muscle, compared to eight post-heart attack patients studied who did not receive the stem cell infusions. One year after, scar size was reduced by about 50 percent. "The damaged tissue of the heart was replaced by what looks like healthy myocardium," said Dr. Peter Johnston, a study co-author and an assistant professor of medicine at The Johns Hopkins University School of Medicine. "It's functioning better than the damaged myocardium in the control subjects, and there's evidence it's starting to contract and generate electrical signals the way healthy heart tissue does." While this research is an early … Continue reading →

February 14, 2012, 11:24 AM EST By Ryan Flinn Feb. 14 (Bloomberg) -- Stem cells grown from patients’ own cardiac tissue can heal damage once thought to be permanent after a heart attack, according to a study that suggests the experimental approach may one day help stave off heart failure. In a trial of 25 heart-attack patients, 17 who got the stem cell treatment showed a 50 percent reduction in cardiac scar tissue compared with no improvement for the eight who received standard care. The results, from the first of three sets of clinical trials generally needed for regulatory approval, were published today in the medical journal Lancet. “The findings in this paper are encouraging,” Deepak Srivastava, director of the San Francisco-based Gladstone Institute of Cardiovascular Disease, said in an interview. “There’s a dire need for new therapies for people with heart failure, it’s still the No. 1 cause of death in men and women.” The study, by researchers from Cedars-Sinai Heart Institute in Los Angeles and Johns Hopkins University in Baltimore, tested the approach in patients who recently suffered a heart attack, with the goal that repairing the damage might help stave off failure. While patients getting the stem … Continue reading →

SOUTH SAN FRANCISCO, CA--(Marketwire -02/14/12)- VistaGen Therapeutics, Inc. (OTC.BB: VSTA.OB - News) (OTCQB: VSTA.OB - News), a biotechnology company applying stem cell technology for drug rescue and cell therapy, has identified its initial Top 10 drug rescue candidates and plans to launch two formal drug rescue programs by the end of next quarter. VistaGen's goal for each of its stem cell technology-based drug rescue programs is to generate and license a new, safer variant of a once-promising large market drug candidate previously discontinued by a pharmaceutical company no earlier than late-preclinical development. "We are now at an advanced stage in our business model," said Shawn Singh, VistaGen's Chief Executive Officer. "After more than a decade of focused investment in pluripotent stem cell research and development, we are now at the threshold where game-changing science becomes therapeutically relevant to patients and commercially relevant to our shareholders. We have positioned our company and our stem cell technology platform to pursue multiple large market opportunities. We plan to launch two drug rescue programs by the end of the next quarter." Over the past year, VistaGen, working with its network of strategic partners, identified over 525 once-promising new drug candidates that meet the Company's … Continue reading →

ScienceDaily (Feb. 13, 2012) — Results from a Cedars-Sinai Heart Institute clinical trial show that treating heart attack patients with an infusion of their own heart-derived cells helps damaged hearts re-grow healthy muscle. Patients who underwent the stem cell procedure demonstrated a significant reduction in the size of the scar left on the heart muscle by a heart attack. Patients also experienced a sizable increase in healthy heart muscle following the experimental stem cell treatments. One year after receiving the stem cell treatment, scar size was reduced from 24 percent to 12 percent of the heart in patients treated with cells (an average drop of about 50 percent). Patients in the control group, who did not receive stem cells, did not experience a reduction in their heart attack scars. "While the primary goal of our study was to verify safety, we also looked for evidence that the treatment might dissolve scar and regrow lost heart muscle," said Eduardo Marbán, MD, PhD, the director of the Cedars-Sinai Heart Institute who invented the procedures and technology involved in the study. "This has never been accomplished before, despite a decade of cell therapy trials for patients with heart attacks. Now we have done … Continue reading →

PIEDMONT, Okla. -- Stem cell research is one of the newest and most exciting areas of study. Experts believe these tiny unwritten cells hold the keys to curing a number of diseases and debilitating injuries. But here in the U.S., stem cell research isn't moving fast enough for a growing number of families. This is the story of an Oklahoma family that traveled to China for cutting-edge stem cell treatment not offered in the US. Cora Beth Taylor walks a different road than most will ever travel. Her journey is filled with obstacles, heartbreak and triumph. Cora, William and Tate Taylor are triplets born premature. The brothers have never shown any signs of prematurity. But Cora, at about a year old, started falling behind developmentally. By 18 months she had been diagnosed with Cerebral Palsy. Cora has never had any cognitive delays. She's a super-smart little gal but her muscles haven't developed properly. It's devastating; they just won't cooperate. Cora's parents, Kevin and Beth Taylor, have tried everything for their little girl; that is, everything available in the U.S. Last year, Piedmont Schools raised the money to help the Taylors take Cora to China for treatment, close to $50,000.
