Cystatin A (CSTA) and cathepsin B expression in tumor‐infiltrating immune cells from patients with pancreatic ductal adenocarcinoma. (a, b) Representative images of the substantial presence (patient no. 6) (a) and minimal presence (patient no. 11) (b) of CSTA in tumor‐infiltrating immune cells. CSTA‐positive infiltrating cells (arrows) are mainly neutrophils. (c, d) Representative images of the substantial presence (patient no. 6) (c) and minimal presence (patient no. 8) (d) of cathepsin B in tumor‐infiltrating immune cells. Cathepsin B‐positive cells are mainly macrophages. Scale bar = 100 μm.
