Scientists in Massachusetts have in the lab get the small blood vessels grow from stem cells in vitro. Researchers have created the blood vessels having a larger diameter before, but the formation of blood vessels with a small diameter can not replace the work of the capillary blood flow, and other tissues and organs. Capillaries - the smallest blood vessels in the human body, which are suitable for transport of nutrients and blood flow to organs and tissues. U.S. scientists now plan to test the artificial capillaries in animals. Grown in the laboratory to the smallest blood vessels - a breakthrough in regenerative medicine, said a British scientist.
