Endothelial progenitor cell

Patent Pending Endothelial progenitor cells (EPC) are a population of rare cells that circulate in the blood with the ability to differentiate into endothelial cells, the cells that make up the lining of blood vessels. The process by which blood vessels are born de novo from endothelial progenitor cells is known as vasculogenesis. Endothelial progenitor cells participate in pathologic angiogenesis such as that found in retinopathy and tumor growth.
