Histopathology results of H&E staining of colonic dysplasia (A, B, E, F, I, and J) and adenoma (C, D, G, H, K, and L) induced by AAT/DSS, DMBA/DSS or ENU/DSS. Figs. B, D, F, H, J, and L are enlarged magnifications of those in A, C, E, G, I, and K, respectively (the areas surrounded by the yellow frames). Yellow bar: 100 μm
