The heart pumps blood to the entire body by repeated contraction and relaxation of the heart muscles. Human stem cells are used in the clinical therapies of a dead heart, which happens when a blood vessel is clogged or whole or a part of the heart muscle is damaged. The clinical use of human bone marrow-derived mesenchymal stem cells (BM-MSCs) has been expanded but failure of the transplanted stem cells in the heart still remains a problem.
