Scientists have found a previously unrecognized group of stem cells located in the surface of the heart that give rise to heart muscle cells, which researchers believe could help regenerate injured heart tissue.

Researchers at Children's Hospital Boston believe finding these stem cells, located on the surface of the heart, or epicardium, may lead to ways to regenerate injured heart tissue. Earlier research had shown that epicardial cedlls give rise to smooth muscle and endothelial cells during coronary vessel formation. This finding that epicardial cells might turn into cardiomyocytes came as a surprise
