Histological characteristics of skin tumor formation. H&E staining of the vehicle-treated epidermis after 12 weeks is shown (a). The epidermis after 4 (b), 6 (c), 8 (d) and 12 (e) weeks of the classical two-stage chemical carcinogenesis protocol revealed striking abnormalities in epidermal architecture consistent with tumor formation, including the appearance of pseudohorn cysts (marked with stars). The dorsal skin of the mouse after 12 weeks of DMBA/TPA treatment is shown (f). Both Ki67-positive cells (g) and CD3-positive infiltrates (h) were evident throughout the experimental protocol (12 weeks is shown). BL: basal layer; SB: suprabasal compartment.
