Interestingly, vCAFs shared many marker genes with pericytes, including platelet-derived growth factor receptor beta (PDGFRβ), Chondroitin Sulfate Proteoglycan 4 (CSPG4), and regulator of G protein signaling 5 (RGS5), which further supported its association with vascularization and tumor invasion. This evidence concerns the gene RGS5 and neoplasm.
