PECAM1 and neoplasm: All cells were eventually assigned to 8 distinct cell types (Figure 5A) with specific markers: EPCAM, ALDH1A1 and ALB for epithelial and tumour cells; CD79A and MS4A1 for B cells; CD3D and CD3E for T cells; FGFBP2 for natural killer (NK) cells; ITGAM, CD33, CD68, CD14 and CD163 for monocytes and macrophages; ITGAX for dentritic cells; ACTA2 and COL1A2 for fibroblasts; PECAM1 for endothelial cells (Figure 5B).
