Pericytes are vascular mural cells embedded in the basement membrane of blood microvessels. They extend their processes along capillaries, pre-capillary arterioles and post-capillary venules. Pericytes regulate blood-brain barrier (BBB) permeability, angiogenesis, clearance, cerebral blood flow (CBF), neuroinflammation and stem cell activity. https://www.creative-bioarray.com/filter/pericytes-105.html
