New source of heart stem cells found
Paris: Researchers in the US have discovered a new group of stem cells that can give rise to heart muscle cells, known as cardiomyocytes, according to a study published on Sunday. The stem cells are located in the outermost layer of the heart and could one day play a critical role in regenerating injured heart tissue, the researchers say. "In heart failure, you lose cardiomyocytes, so the only way to reverse heart failure is to make more of these cells,' said William Pu, the study's lead researcher. The new findings come on the heels of two earlier breakthroughs.
