Fine-Tuning Stem Cell Therapy to Repair the Heart

By BiotechDaily International staff writers
Posted on 27 Mar 2013
Stem cells have the potential to grow into a range of cell types, including heart cells. Researchers are now trying to refine the process of repairing and regenerating heart tissue damaged by a heart attack with stem cells.

A recent study from Cedars-Sinai Heart Institute (Los Angeles, CA, USA) suggests that stem cells may, undeniably, heal damaged hearts. The researchers treated 17 heart attack survivors with an infusion of stem cells taken from their own hearts. One year later, the amount of scar tissue had shrunk by about 50%. These findings look dramatic, but investigators are wondering if they an indication that they are close to perfecting stem cell therapy.

“This is a field where, depending on which investigator you ask, you can get incredibly different answers,” Dr. Richard Lee, professor of medicine at Harvard Medical School (Boston, MA, USA), and a leading specialist on stem cell therapy, reported in the March 2013 issue of Harvard Women’s Health Watch. “The field is young. Some studies show only modest or no improvement in heart function, but others have shown dramatically improved function. We’re waiting to see if other doctors can also achieve really good results in other patients.”

New research is generating contrary findings in part, because researchers use diverse approaches to harvest and use stem cells. Some are gathered from the bone marrow of donors, others from the recipient’s own heart. It is not evident which approach works optimally. “Some investigators think this is just a few years away,” concluded Dr. Lee. “And then there are others who feel that there is much more work to be done.”

Presently, stem cell therapy is available only to individuals who participate in a research trial.
