WebIntroduction. Although both pericytes and vascular smooth muscle cells arise from the mural cell population and both contribute to vessel wall stability and tone (Kumar et al., 2024), these cells play critical but distinct roles in regulating vascular structure and remodeling.In smaller vessels and capillaries, pericytes cover and directly interact with the … WebMar 26, 2024 · Pericyte/smooth muscle cells expressed genes implicated in regulation of cellular apoptosis and extracellular matrix organization, and several ligands for genes showing increased expression in endothelial cells.
