Pericytes angiogenesis
WebJul 22, 2003 · It takes two to make blood vessels—endothelial cells and pericytes. While the endothelial cells are the better characterized of the two, pericytes are now coming into focus as important regulators of angiogenesis and blood vessel function, and as potential drug targets. However, pericytes are still surrounded by much controversy. They are difficult to … WebMar 1, 2024 · Pericytes can be recruited in the last step of angiogenesis through the platelet-derived growth factor-BB (PDGF-BB)/PDGFR-β signaling pathway and establish communication with endothelial cell receptors. In the TME, multiple signaling pathways act together to cause tumor angiogenesis.
