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.

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. 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 of pericytes located in the walls of capillaries, at the place where the metabolic demand occurs and could be most rapidly sensed (3). The contractility of cultured pericytes is well established and, of all organs, capillaries in the central nervous system (CNS) are endowed with the highest number of pericytes (4). Pericytes of Pericytes are contractile cells that surround capillaries in the brain at high density. The traditional view that CBF is regulated solely by precapillary arterioles has recently been challenged by studies in retina and cerebellar slices ( 6 ), as well as in ischemic brain tissue ( 12 ). Pericytes (previously known as Rouget cells) are multi-functional mural cells of the microcirculation that wrap around the endothelial cells that line the capillaries and venules throughout the body. Pericytes are embedded in basement membrane , where they communicate with endothelial cells of the body's smallest blood vessels by means of both direct physical contact and paracrine signaling .

They are crucial for brain development and contribute to CNS homeostasis by regulating blood-brain barrier function and cerebral blood flow. 2010-12-06 pericytes located in the walls of capillaries, at the place where the metabolic demand occurs and could be most rapidly sensed (3). The contractility of cultured pericytes is well established and, of all organs, capillaries in the central nervous system (CNS) are endowed with the highest number of pericytes (4).

Pericytes—small, specialized cells on the surface of capillaries—have a significant impact on vascular homeostasis. A better understanding of their prominent role in the pathogenesis of DR, and possibly other ocular diseases, can help spur the development of potential therapeutic targets to delay or treat this leading cause of vision loss. Pericytes surround blood vessel capillaries and endothelial cells, neurons and astrocytes within the blood-brain-barrier (BBB) neurovascular unit. Pericytes, also known as mural cells, are multipotent perivascular cells that play an important role in the development, maturation, and remodeling of blood vessels.

Pericytes also have long thin arms that stretch along each capillary like a snake on a tree branch. These arms, called processes, reach almost to where the next pericyte process begins, without overlapping. 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. 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.
