Tumour microenvironment compartments. Representative image of a human low-grade IPMN tissue section stained with H&E. Immune cell populations were quantified in distinct areas, juxtatumoral (red) and peritumoral (yellow) stroma, tertiary lymphoid structures (green), and normal adjacent pancreatic tissue (purple). Scale bar represents 100 μm². The H&E image was acquired at 20x magnification.
