WebJul 22, 2003 · It takes two to make blood vessels—endothelial cells and pericytes. While the endothelial cells are the better characterized of the two, pericytes are now coming into focus as important regulators of angiogenesis and blood vessel function, and as potential drug targets. However, pericytes are still surrounded by much controversy. They are difficult to … WebAngiogenesis is a primary compensatory response to decreased tissue oxygenation. Normal tissue oxygen levels vary within and among organs but typically fall in a range of 3–9%, substantially less than the 21% present in air. Within cells this is …
