Pericyte endothelial

Webpericytes enhanced the proliferation of cocultured endothelial cells (1.3-fold, P = 0.002). Finally, we identified inflammatory signaling molecules, including MCP-1 and interleukin 8 (IL-8) that may mediate the crosstalk between peri-cytes and endothelial cells. The results of this study show that pericyte NF-jB WebA single pericyte has numerous extended processes, and different processes may be in contact with different endothelial cells. The cell processes of the pericytes and the cytoplasm of the endothelial cells are configured in a “peg and socket” arrangement, which supports an intimate crosstalk between the pericytes and the endothelial cells.
