a CD68-positive macrophages in normal liver tissue. Normal liver parenchyma revealed a homogenous infiltration pattern with no preference for perivascular areas or clumping of TAMs. Original magnification: x 200; scale bar = 50 μm. b Hilar cholangiocarcinoma stained with mAb CD68 PG-M1 with a high abundance of TAMs (tumorous tissue “TT” score 3). Original magnification: x 200; scale bar = 50 μm. c Tumor infiltration front (TIF) positive for CD68-positive TAMs (TIF score 2 / high abundance / positive). Original magnification: x 200; scale bar = 50 μm
