Cardiac progenitor cells (CPC) are a unique pool of progenitor cells residing in the heart that play an important role in cardiac homeostasis and physiological cardiovascular cell turnover during acute myocardial infarction (MI). Transplanting CPC into the heart has shown promise in two recent clinical trials of cardiac repair (SCIPIO & CADUCEUS). CSCs were originally isolated directly from enzymatically digested hearts followed by cell sorting using stem cell markers. However, long exposure to enzymatic digestion can affect the integrity of stem cell markers on the cell surface and also compromise stem cell function. Here, we describe a two-step procedure in which a large number of intact cardiac progenitor cells can be purified from small amount of heart tissue.
