Heart disease is the leading cause of death in the industrialized world, and stem cell therapy seems to be a promising treatment for injured cardiac tissue. To reach this goal, the scientific community needs to find a good source of stem cells that can be used to obtain new myocardium in a very period range of time. Since there are many ethical and technical problems with using embryonic stem cells as a source of cells with cardiogenic potential, many laboratories have attempted to isolate potential cardiac stem cells from several tissues. The best candidates seem to be cardiac "progenitor" and/or "stem" cells, which can be isolated from subendocardial biopsies from the same patient or from embryonic and/or fetal myocardium. Regardless of the technique used to isolate and characterize these cells, it appears that the different cells isolated from adult myocardium to date are all phenotypic variations of a unique cell type that expresses several markers, such as c-Kit, CD34, MDR-1, Sca-1, CD45, nestin, or Isl-1, in various combinations.
