They are crucial for brain development and contribute to CNS homeostasis by regulating blood-brain barrier function and cerebral blood flow. pericytes of pre-capillary arterioles (PCA) and capillaries that expressed NG2-DsRed florescence, weakly NG2(+) pericytes in post-capillary venules (PCV), and NG2 negative [NG2(–)] venular pericytes. We investigated the mechanisms underlying the synchrony of spontaneous Ca2+ transients amongst mural cells in the same 2018-07-01 · Pericytes are vascular mural cells that can constrict or relax around capillaries, mediating local cerebral blood flow control. They participate in the constriction observed during brain ischaemia and might be involved the disruption of the microcirculation during spreading depolarization. In capillaries and PCAs, NG2(+) pericytes developed nearly‐synchronous spontaneous Ca 2+ transients at a similar frequency that was lower than that of pericytes in PCVs or venules, although Ca 2+ transients in PCA pericytes seldom spread into NG2(+) SMCs in the arterioles. 2020-12-09 · Typically, pericytes are surrounded by a basement membrane, and present an archetypal morphology ranging from spindle to stellate across the microvascular tree 19. Functional vascular capillaries 2021-01-15 · Pericytes are located on the abluminal capillary side of the endothelium and consist of a central cell body with multiple fingers that grip the capillaries [10,11].

Pericytes are located on the abluminal capillary side of the endothelium and consist of a central cell body with multiple fingers that grip the capillaries [ 10, 11 ]. Pericytes are found on almost all capillaries, as well as on small arterioles and venules.
