For instance, genes highly expressed in B cells included CD79A and MS4A1, endothelial cells specifically expressed PLVAP, VWF, and EMCN, fibroblasts specifically expressed COL3A1 and COL1A2, NKT cells specifically expressed GZMA, NKG7, and GNLY, while proliferative tumor cells and tumor cells expressed specific tumor marker genes such as MKI67 and EPCAM, respectively (Fig. 6B). This evidence concerns the gene COL3A1 and neoplasm.
