Additionally, we analyzed the expression patterns of cell-specific genes (such as EPCAM, ALDH1A1, and ALB for epithelial and tumor cells; CD79A and MS4A1 for B cells; CD3D and CD3E for T cells; FGFBP2 for NK cells; ITGAM, CD33, CD68, CD14, and CD163 for monocytes and macrophages; ITGAX for dendritic cells; ACTA2 and COL1A2 for fibroblasts; and PECAM1 for endothelial cells) (Figures 1B and 1C). The gene discussed is MS4A1; the disease is neoplasm.
