Stem Cells Boost Heart's Natural Repair Mechanisms

 Injecting specialized cardiac stem cells into a patient's heart rebuilds healthy tissue after a heart attack, but where do the new cells come from and how are they transformed into functional muscle?
Researchers at the Cedars-Sinai Heart Institute, whose clinical trial results in 2012 demonstrated that stem cell therapy reduces scarring and regenerates healthy tissue after a heart attack, now have found that the stem cell technique boosts production of existing adult heart cells (cardiomyocytes) and spurs recruitment of existing stem cells that mature into heart cells. The findings, from a laboratory animal study, are published in EMBO Molecular Medicine online
