1 Nov 2005 Pericytes and endothelial cells communicate with each other through gap junctions, tight junctions, soluble factors, and cell surface adhesion

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.

Pericytes and endothelial cells

Primary and subculture (up to the second passage) of retinal pericytes and endothelial cells were established from bovine retinas dissected from eyes of freshly slaughtered cattle. The retinas were homogenised in serum- was released by endothelial cells first cocultured with pericytes and then incubated with LPS in the absence of pericytes. Pericytes (in contrast to endothelial cells and astrocytes) were found to be the principal in vitro source of the serpin protease nexin-1 (PN-1), known to have primarily antithrombin effects. Human endothelial cells (ECs) were cultured from cord blood human endothelial colony-forming cells (HECFCs) in EGM2 medium (Lonza).31 Pericytes (PCs) were isolated and cultured in M199 medium (Gibco) supplemented with 20% fetal bovine serum and 1% Pen/Strep.32 Fluorescence ﬂow cytometry conﬁrmed that cultured 2 Jul 2020 Pericytes (PCs), cells that extend along capillaries to contribute stability and other critical functions to established vasculature, are attracting Abstract. Objective: Pericytes, located in close proximity to the underlying endothelium, form an integral component of the microvasculature. These cells are in.

VEGF coordinates interaction of pericytes and endothelial cells during vasculogenesis and experimental angiogenesis. 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 .

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.

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.

Most of the current research focuses on the role of endothelial cells, however endothelial cell physiology is strongly related to pericyte function.

However, the crosstalk between these two cells is often disrupted by diabetes, resulting in severe and even lethal vascular defects.

2020-07-28 · Formation, maintenance, and repair of the blood–brain barrier (BBB) are critical for central nervous system homeostasis. The interaction of endothelial cells (ECs) with brain pericytes is known to induce BBB characteristics in brain ECs during embryogenesis and can be used to differentiate human ECs from stem cell source in in vitro BBB models. 2020-03-26 · In this study, CD146+cells were enriched from the human bone marrow aspirates and trans-differentiated into mature endothelial cells, pericytes, and cardiomyocytes after exposure to autophagy stimulator (50-μM Met)/inhibitor (15-μM HCQ). The protein levels of autophagy proteins were monitored by western blotting.

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.

Pericytes, along with neurons, astrocytes, microglia, and endothelial cells comprise the neurovascular unit of the BBB. Blood -brain barrier permeability occurs by endothelial transcytosis regulated by pericytes by at least two mechanisms: 1) by regulating BBB-specific gene expression patterns in endothelial cells and 2) by inducing polarization of astrocyte end-feet surrounding CNS blood vessels.

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.
