Endothelial colony-forming cells (ECFCs) derived from human placenta are better for forming blood vessels than the ECFCs derived from umbilical cord blood, according to a new study.The study was carried out by researchers at the Indiana School of Medicine.“Circulating ECFCs isolated from umbilical cord blood and those isolated from human placenta are phenotypically identical and have equivalent proliferative potential,” said study lead author Michael P. Murphy, MD of the Indiana University’s Department of Surgery.Umbilical cord blood and the extra-embryonic membranes of placenta are ideal sources of progenitor cells, said the researchers, because the tissues are discarded as medical waste and ethical concerns facing embryonic stem cells are avoided. The quantity of cells that can be derived from placenta, however, is much greater than the amount that can be derived from umbilical cord blood, making the placenta the more abundant source.They concluded that the placenta represents an abundant source of ECFCs that could provide a therapeutic dose of cells.According to the researchers, the role of circulating ECFCs has yet to be determined, yet circulating mature endothelial cells are rarely found in normal, healthy individuals as they are markers of vascular damage, remodeling and dysfunction.The study has been published in a recent issue of Cell Medicine.
