Physicians and researchers at Cedars-Sinai and Johns Hopkins hosipitals have embarked on an exciting study involving the use of stem cells to fix heart muscle that have been damaged during heart attacks. Heart-specific stem cells are harvested directly from the patient’s own heart and grown in a petri dish. The stem cells form clusters called “cardiospheres” that can even start to beat while in the dish. These cells are then injected back into the damaged heart of the patient from which they came. The researchers are hoping that these new cells will grow into healthy muscle to replace a damaged and scarred heart. This minimally-invasive procedure was completed in the first patient on Friday, June 26, 2009.
