Protective effects of non-mitogenic human acidic fibroblast growth factor on hydrogen peroxide-induced damage to cardiomyocytes in vitro

Figure 2 Cellular morphological change of cardiomyocytes after exposure to different concentrations of hydrogen peroxide for 4 h. A: Normal control group (magnification ×200); B: cardiomyocytes exposure to 1.25 mmol/L H₂O₂ (magnification ×200); C: cardiomyocytes exposure to 2.5 mmol/L H₂O₂ (magnification ×200); D: cardiomyocytes exposure to 5 mmol/L H₂O₂ (magnification ×200).
