Although the expression of six endothelial differentiation marker genes (PECAM1, vWF, FLT1, FLT4, KDR, CDH5) was significantly lower in normal and tumor ADSC, there was significantly greater expression of PDGFRB in ADSC when compared to BEC and NORMA1 MEC cells (Fig. 4d). This evidence concerns the gene PDGFRB and neoplasm.
