Healthline - "Injected Stem Cells Repair Heart Attack Damage"
Stem cells can repair the damage wreaked by heart disease, with cautious optimism from doctors pending the outcomes of clinical trials on humans according to a study published in the journal Cell.
In an experiment on rats, they found that stem cells must be present in order for the heart muscle to repair itself after an attack. Roger Hajjar, MD, Director of the Cardiovascular Research Center at The Mount Sinai Medical Center said that the research is important in that it showed that the cardiac stem cells in question are indeed responsible for the regeneration of heart tissue. "For patients with advanced heart failure who have few therapeutic options, this really opens up the door for novel therapies, some of which are being evaluated right now to repair the heart in a definitive manner," Dr. Hajjar said. "If you have a heart with a lot of scars, and that's why you usually have heart failure, this opens up now what we have identified as the cells that are inducing the repair."
