In addition, we compared the staining of CXCR3 and CD45 (pan-leukocyte marker), CK8 (pancreatic epithelial marker) and α-smooth muscle actin (α-SMA, marker of activated fibroblasts/PSCs) between the tumor and the adjacent normal tissue for each patient (Figure 4A). The gene discussed is ACTA1; the disease is neoplasm.
