[Resident cardiac stem cells].

The search for sources of stem/progenitor cells the use of which has a potential to affect course of ischemic heart disease and chronic heart failure is conducted nowadays in many countries. Resident cardiac stem cells (CSC) were revealed during recent years on the basis of expression of c-kit, sca-1, MDR1, and islet-1 markers. In vitro experiments demonstrated possibility of their differentiation into cardiomyocytes, smooth muscle cell and endothelial cells. Introduction of CSC in injured myocardium in animals facilitated its partial repair and short term improvement of cardiac function. This holds promise for the use of these cells in the future. In the review we have attempted to summarize literature data on resident CSC and their application for the treatment of heart diseases.
