Endothelial progenitor cells are a type of stem cell that has the potential to differentiate into mature endothelial cells, which line the interior surface of blood vessels. These cells play a crucial role in the repair and maintenance of blood vessels, as well as in promoting the formation of new blood vessels in a process called angiogenesis. Endothelial progenitor cells have been the focus of research in regenerative medicine, vascular biology, and cardiovascular disease, as they have the potential to improve blood vessel function and contribute to the treatment of various vascular disorders. Studies have shown that enhancing the function of endothelial progenitor cells can lead to improved blood vessel repair and regeneration, making them a promising target for therapeutic interventions in cardiovascular diseases and vascular disorders.
