FIGURE 2.
(A) HE staining of myocardial tissue from control and DOX-treated groups. The DOX group exhibits disordered cell arrangement, widened muscle fiber gaps, and vacuole-like changes in the cytoplasm; (B) Masson’s trichrome staining of myocardial tissue from control and DOX-treated groups. The DOX group displays pronounced myocardial fibrosis with increased collagen fiber accumulation; (C) TUNEL staining of myocardial tissue from control and DOX-treated groups. The DOX group shows a significant increase in apoptotic myocardial cells.
