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. In the co-cultures, pericytes inhibited all EC proliferation throughout the 14-d time course; similar levels of EC inhibition were observed in SMC-EC co-cultures. Kumar et al. find that mesodermal pericytes and smooth muscle cells in human pluripotent stem cell cultures originate from a common endothelial and mesenchymal cell precursor, the mesenchymoangioblast. They show how different lineages of mural cells are specified from mesenchymoangioblasts and define stage- and lineage-specific markers for vasculogenic cells.

Hagedorn M (1), Balke M, Schmidt A, Bloch W, Kurz H, Javerzat S, Rousseau B, Wilting J, Bikfalvi A. Biological activities of vascular endothelial growth factor (VEGF) have been studied extensively in endothelial cells (ECs), but few Pericytes are also thought to limit endothelial cell proliferation; thus, loss of pericytes can lead to endothelial cell hyperplasia . Pericytes also play a critical role in angiogenesis, because they are typically found near the tips of sprouting vessels and where they are thought to guide the sprouting processes by expressing VEGF ( 166 – 170 ). Pericytes are mural cells that support vascular development, remodeling, and homeostasis, and are involved in a number of pathological situations including cancer. 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.

The crosstalk between vascular endothelial cells (ECs) and pericytes in the microvascular is critical for vascular homeostasis and remodeling. However, the crosstalk between these two cells is often disrupted by diabetes, resulting in severe and even lethal vascular defects.

Pericytes and endothelial precursor cells (EPC) contribute to the formation of blood vessels under angiogenic conditions. As primary cells in culture, pericytes and EPC share many properties such as tube/network formation and response to kinase inhibitors selective for angiogenic pathways. CONCLUSIONS: Pericytes covering endothelial cells were observed not only in vasculature of normal retina but also pathologic neovascularization of OIR mouse at P17. Factors involved in the endothelial cell-pericyte interaction can be evaluated as an attractive novel treatment target. Pericytes (PCs) wrap around endothelial cells (ECs) and perform diverse functions in physiological and pathological processes. Although molecular interactions between ECs and PCs have been extensively studied, the morphological processes at the cellular level and their underlying mechanisms have remained elusive.

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. In areas where the BM is absent between the endothelial cells and pericytes, different types of endothelial/pericyte cell contacts have been described. 4 In adhesion plaques, the intercellular space between the 2 cell types is maintained and contains fibronectin deposits. 5 Areas called peg–socket contacts represent membrane invaginations Human endothelial cells (ECs) and pericytes are of great interest for research on vascular development and disease, as well as for future therapy. This protocol describes the efficient generation of ECs and pericytes from human pluripotent stem cells (hPSCs) under defined conditions. CONCLUSIONS: Pericytes covering endothelial cells were observed not only in vasculature of normal retina but also pathologic neovascularization of OIR mouse at P17. Factors involved in the endothelial cell-pericyte interaction can be evaluated as an attractive novel treatment target.

Migrated CD34 + cells differentiate into both endothelial cells and pericytes in the expanding tumor vessel network, whereas CD34 − cells differentiate into macrophages. A. Sorted CD34 + /CD38 − cells were gfp labeled and intravenously injected into nude mice with TC71 tumors. Neovascular formation is initiated by the activation of quiescent vessels in response to angiogenic signals, such as vascular endothelial growth factor (VEGF), angiopoietin 2 (ANG‐2), or chemokines.

1–8 These cells act in concert with one another to create a functional vascular plexus, capable of supporting tissue development, and maintenance via communications with adjacent tissues to promote tissue health. 4,5,7 It is essential to understand the detailed molecular and cellular biology of capillary network assembly in health and in Pericytes and endothelial cells communicate with each other through gap junctions, tight junctions, soluble factors, and cell surface adhesion molecules (4, 5). EPC can be derived from CD34+/CD133+ bone marrow progenitor cells driven by angiogenic stimuli towards an endothelial phenotype (6–8). EPC are characterized by their ability to form Biological activities of vascular endothelial growth factor (VEGF) have been studied extensively in endothelial cells (ECs), but few data are available regarding its effects on pericytes. In murine embryoid body cultures, VEGF-induced expression of desmin and -smooth muscle actin ( -SMA) in CD-31 cells.

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.
