Several recent studies in animals as well as humans support the notion that bone marrow (BM)-derived cells participate in myocardial regeneration. However, this subject remains highly controversial and the identity of the specific cell type responsible for regeneration remains unknown. Recent work from our laboratory revealed that BM contains a highly mobile population of CXCR4+ cells that express mRNA for various markers of early tissue-committed stem cells (TCSC) and which are distinct from hematopoietic stem cells (HSC) (
