Researchers regenerate heart cells in mice

from By Lynn Hetzler

Myocardial infarction, or MI, causes irreversible necrosis of heart muscle secondary to prolonged ischemia. Scar tissue begins to build almost immediately, leading to the loss of contractile myocardium, which is a frequent cause of chronic heart failure. However, a new study suggests there may someday be a way to stimulate the body into regenerating heart cells after MI. The research results, published in Nature Cell Biology, may eventually help clinicians reduce cardiomyopathy and stimulate cell regeneration in heart attack patients. more
