Researchers at the Cedars-Sinai Heart Institute in Los Angeles used stem cells from patients' own heart tissue to reverse the damage caused by a heart attack. Heart scars in patients who received stem cell infusions were reduced in size from 24% to 12% of the heart, according to the study published in The Lancet. The lead researcher said the study shows the heart can regrow healthy tissue, contrary to popular belief that cardiac scarring is permanent.
