The markers for each cell type included ductal cells (KRT19, KRT8, and CFTR), macrophages (LYZ, CD68, and C1QB), T cells (CD3D, CD3E, and NKG7), acinar cells (CLPS, CELA2A, and CELA3A), cancer-associated fibroblasts (FAP, COL1A1, and POSTN), endothelial cells (VWF, CDH5, and ERG), plasma cells (JCHAIN, MZB1, and JSRP1), pericytes (ACTA2, RGS5, and TAGLN), mast cells (KIT, CPA3, and TPSAB1), B cells (CD79A, CD79B, and MS4A1), and endocrine cells (GCG, INS, and GAS5) (Figures 1B, C). Here, MZB1 is linked to cancer.
