Pericytes: Purpose and Function - News-Medical.net

Pericytes in the skeletal striated muscle are of two distinct populations, each with its own role. The first pericyte subtype (Type-1) can differentiate into fat cells while the other (Type-2) into muscle cells. Type-1 characterized by negative expression for nestin (PDGFRβ+CD146+Nes-) and type-2 characterized by positive expression for nestin (PDGFRβ+CD146+Nes+). While both types are able to proliferate in response to glycerol or BaCl2-induced injury, type-1 pericytes give rise to adi… WebIn this review, we examine the mechanism of pericyte support to vasomotion, and the known pathways that regulate pericyte response in angiogenesis and neovascular …
