PDGFRB and neoplasm: Because we have reported the function of PDGFRβ in mediating tumor vasculogenic properties in TNBCs [28], and we also reported that CDCP1 knocked-down impairs vasculogenic mimicry in vitro, TNBC tumors were then analyzed, based on the presence or absence of PDGFRβ staining in association with tumor cells in vascular-like structures or organized into tumor nests.
