PDGFRB and cancer: Differential gene activity levels for marker genes allowed us to identify cancer cells (KRT5, KRT15, CXCR4, TERT, TP63), cancer-associated fibroblasts or CAFs (COL1A2, LUM, FAP, VEGFC, ANGPT1, PDGFRB, IL6, CXCL8, CXCL12) and endothelial cells (CDH5, EGFL7) (Fig. 4b and Supplementary Figs. 10b–e and  11b–e).
