The dynamic interplay between pericytes and endothelial cells is at the basis of vascular physiology and few experimental tools exist to properly describe and study it. 2003-05-01 · A typical intimate association was seen between endothelial cells and pericytes in the untreated tumors, as well as in the SU5416-treated tumors (Figure 2; right panel). By contrast, SU6668-treated tumors showed marked disruption of pericyte-endothelial cell association. Cell migration of endothelial cells and pericytes is uncorrelated, which has the important direct consequence that contact of pericytes and endothelial cells is indirect through the basal membrane.
Hi guys. I'm attempting to isolate primary endothelial cells, and am having trouble with pericyte contamination of cultures. Electrical resistance of primary cultures of pericytes, astrocytes and endothelial cells, as measured by ECIS Zθ. (a) Transcellular electrical resistance comparison between pericytes (PCs comprised of two cell types-endothelial cells (ECs) 1 and pericytes. Pericytes exist in intimate association with ECs, forming a single layer that covers vary- ing amounts of the abluminal EC surface. This arrangement, unique to small vessels, is characterized by frequent sites of contact between the ECs and pericytes. Since pericytes and other modulating cells were growth arrested, any cell number change in co-cultures was due to EC growth.

The dynamic interplay between pericytes and endothelial cells is at the basis of vascular physiology and few experimental tools exist to properly describe and study it. Endothelial cells comprise the inner lining of vessels whereas pericytes encompass blood microvessels such as blood capillaries, precapillary arterioles, precapillary venules, and collecting venules.1 Pericytes use cytoplasmic processes to surround the abluminal surface of the endothelial tube.2 They share and coproduce a basement membrane with endothelial cells, demonstrating that pericyte-endothelial interaction plays a key role in basement membrane formation, maintenance, and remodeling. While a monolayer of endothelial cells (ECs) encloses the vessel lumen, mural cells, namely pericytes, are associated with the abluminal surface of capillaries. Combined neutralization of the above endothelial cell-derived factors or pharmacological blockade of their pericyte receptors markedly interferes with pericyte recruitment and responsiveness to endothelial cell-lined tubes, which behave as if pericytes were not present. In this study, three protocols used to isolate, enrich and characterize primary mouse endothelial cells, pericytes and astrocytes are presented.
Pericytes (also known as vascular smooth muscle cells, mural cells, or myofibroblasts) wrap around the endothelial cells. Pericytes share the same basal lamina with the endothelial cells and form an incomplete covering around the abluminal surface of endothelial cells (3). Endothelial cells are progenitors of cardiac pericytes and vascular smooth muscle cells Mural cells of the vessel wall, namely pericytes and vascular smooth muscle cells, are essential for vascular integrity. The developmental sources of these cells and molecular mechanisms controlling their progenitors in the heart are only partially understood.
