In the kidney, pericyte is the major source of myofibroblast(MyoF) in renal interstitium. It is reported that pericyte-myofibroblast transition(PMT)is one of the important pathomechanisms of renal interstitial fibrosis(RIF). Among them, the main reasons for promoting RIF formation include pericyte recruitment, activation and isolation, as well as the lack of pericyte-derived erythropoietin. During the PMT startup process, pericyte activation and its separation from microvessels are controlled by multiple signal transduction pathways, such as transforming growth factor-β(TGF-β)pathway, vascular endothelial growth factor receptor(VEGFR) pathway and platelet derived growth factor receptor(PDGFR) pathway;Blocking of these signaling pathways can not only inhibit PMT, but also suppress renal capillaries reduction and further alleviate RIF. In clinic, many traditional Chinese medicine compound prescriptions, single traditional Chinese herbal medicine(CHM) and their extracts have the clear effects in alleviating RIF, and some of their intervention actions may be related to pericyte and its PMT. Therefore, the studies on PMT and its drug intervention will become the main development direction in the research field of anti-organ fibrosis by CHM.
