Autologous and Adult Stem Cells Transplant in Mexico
http://www.mexicohealth.com The video shows a top stem cell specialist in Mexico explaining why autologous stem cell treatment is a better choice than adult stem cell transplant. The doctor goes on to caution about risks of reaction in case of adult stem cells transplant. In some cases, the reaction could kill. Autologous, on the other hand, is a safe proposition. The doctor has been in the profession since 1978 and has treated over 40 patients with acute degenerative disorders like, multiple sclerosis.

Autologous and Adult Stem Cells Transplant in Mexico - Video

Washington, November 6 (ANI): Administering to patients stem cells derived from their own bone marrow either three or seven days after a heart attack is safe but does not improve heart function six months later, according to a clinical trial.

The results of the trial, called Transplantation In Myocardial Infarction Evaluation (TIME), mirror a previous, related study, LateTIME, which found that such cells (called autologous stem cells) given two to three weeks after a heart attack did not improve heart function.

Both TIME and LateTIME were conducted by the Cardiovascular Cell Therapy Research Network (CCTRN), sponsored by the NIH's National Heart, Lung, and Blood Institute.

"This study was extremely valuable even though it did not provide a demonstrated health benefit after six months," said Sonia Skarlatos, Ph.D., deputy director of NHLBI's Division of Cardiovascular Sciences and member of the CCTRN.

"Heart stem cell therapy research is still in its infancy, and results from early trials have varied greatly due to differences in the numbers of stem cells injected, the delivery methods used, and the compositions of the study populations. With TIME and LateTIME, we have established both safety and baseline results in two large studies that followed the same procedures for growing and then administering stem cells. This standard will inform the next steps in research on the use of stem cells to repair damaged hearts," she stated.

Fellow CCTRN member Jay Travese, M.D., of the Minneapolis Heart Institute added, "With this baseline now set, we can start to adjust some of the components of the protocol to grow and administer stem cell to find cases where the procedure may improve function."

"For example, this therapy may work better in different population groups, or we might need to use new cell types or new methods of delivery," he noted.

Skarlatos said that another advantage of the TIME study is that CCTRN is storing samples of the stem cells taken from the participants. Investigators can examine the relationship between people who showed significant improvement during the study and the characteristics of their stem cells. Such a comparison may offer insights on the cell traits that are associated with clinical improvement.

The findings will be presented at the American Heart Association (AHA) 2012 Scientific Sessions in Los Angeles and will appear concurrently in the Journal of the American Medical Association. (ANI)

Stem cell therapy may not improve recovery after heart attack

RIO DE JANEIRO--(BUSINESS WIRE)--

CryopraxisTM/CellPraxis aims to start patient recruitment for its Phase III Refractory Angina Cell Therapy Brazilian arm clinical trial by the end of 2012 or early 2013. The phase IIA/B clinical trial study was completed in December 2011. These trials involved the use of a proprietary autologous stem cell formulation (MonocellTM) indicated for neoangiogeneses.

Safety and efficacy of this product was evaluated in patients with refractory angina, a no option disease condition, characterized by severe chest pain for which there is no efficient treatment available, says the President of both Companies, Eduardo Cruz.

ReACT, MonocellTMs derived product, showed evidence of safety and efficacy in our initial clinical trials. All patients included in this trial were classified as Class IV Angina in CCSAC* (the most severe class of chest pain). In the first group of patients, whose data was published**, there was a progressive and sustained improvement in angina symptoms, with 87.5% of the patients completing the clinical trial with a CCSAC score of 0 or 1.

Angina symptom relief began as early as 3 months post procedure with continuing improvement through the 18th month, suggesting that angiogenesis began early, and that it kept evolving 18 months after the procedure. Objective evaluation of stress myocardium perfusion (scintigraphic analysis), after 1 year of follow-up, gave indications of complete myocardial reperfusion in 75% of the patients, says Dr. Nelson Hossne, Medical Director of CellPraxis. Our conclusion was ReACT's specific cell formulation, MonoCell, had a direct correlation to myocardial neoangiogeneses.

LOS ANGELES (AP) - Researchers are reporting a key advance in using stem cells to repair hearts damaged by heart attacks.

In a study, stem cells donated by strangers proved as safe and effective as patients' own cells for helping restore heart tissue.

The work involved just 30 patients in Miami and Balitmore, but proves the concept that anyone's cells can be used to treat such cases. Doctors are excited because this suggests that stem cells could be banked for off-the-shelf use after heart attacks, just as blood is kept on hand now.

Results were discussed on Monday at an American Heart Association conference in California and published in the Journal of the American Medical Association.

Stem cells from strangers can repair hearts: Study

(Reuters) - Stem cells culled from the bone marrow of healthy donors work as well or even better as cells harvested from patients themselves as a treatment for damaged hearts and are more convenient to use, according to new research.

The 13-month trial was the first to compare the safety and effectiveness of so-called mesenchymal, or bone marrow-derived, stem cells taken from patients themselves versus those provided by donors.

Such adult stem cells that renew themselves and mature into specific cell types have been used for 40 years in bone marrow transplants.

Scientists are now exploring their use as treatments for ailments such as heart disease and inflammatory conditions, some of the biggest markets in medicine.

The rationale behind using patients' own stem cells to treat disease is that they do not trigger an attack by the body's immune system. Mesenchymal stem cells, however, are also not recognized as foreign tissue.

Researchers from the University of Miami Miller School of Medicine, funded by the National Institutes of Health, found that previously prepared cells from a healthy donor were comparatively safe and may offer the most convenience since it takes up to eight weeks to grow the amount of stem cells needed for the treatment.

The study involved 30 patients whose hearts were damaged by an earlier heart attack. Half received heart-muscle injections of their own cells, while the other half received donor cells.

Scar tissue was reduced by 33 percent in both groups, a result researchers called "very, very significant."

Improvements in heart function were seen in 28 percent of those receiving donor cells, and in 50 percent of patients receiving their own cells.

After a year, five patients in the donor cell group and eight who received their own cells suffered serious adverse events.

The cells were delivered through a tube pushed through a groin artery into the heart near the scarred area. Fifteen patients were given cells from their own marrow and 15 others, cells from strangers.

About a year later, scar tissue had been reduced by about one-third. Both groups had improvements in how far they could walk and in quality of life. There was no significant difference in one measure of how well their hearts were able to pump blood, but doctors hope these patients will continue to improve over time, or that refinements in treatment will lead to better results.

The big attraction is being able to use cells supplied by others, with no blood or tissue matching needed.

Juan Lopez received his own cells in the study, and said it improved his symptoms so much that at age 70, he was able to return to his job as an engineer and sales manager for a roofing manufacturer and ride an exercise bike. It has been a life-changing experience, said Lopez, who lives in Miami. I can feel day by day, week by week, month by month, my improvement.
