Figure 3. Histological analysis of skin tumors induced by 7,12-dimethylbenz(a)anthracene (DMBA)/12-O-tetradecanoyl phorobol-13-acetate (TPA) treatment in mice removed after 20 weeks. Periodic acid Schiff (PAS) staining revealed the differences concerning several morphological features between the control (A–C), gavage treated groups (D–F), intraperitoneal treated groups (G–I), 5% treated groups (J–L), and the 50% topical treated groups (M–O). Black brackets points to the intensity of hyperplasia, black arrows point to hyperkeratosis, and black arrow heads indicate the levels of infiltration and the density of collagen core bundles. 200× magnification.
