Representative photomicrographs of H&E-stained (a) colonic mucosa from control, (b) active UC patients (severe inflammation; higher score 5.4), and (c) CAC patients (severe inflammation; higher score 5.4). Arrows show cellular infiltrate and crypt destruction (UC, ulcerative colitis, ; CAC, colitis associated cancer, ; C, control, ).
