Sodium Tanshinone IIA Sulfonate Prevents Radiation-Induced Toxicity in H9c2 Cardiomyocytes

Figure 3

Hoechst 33258 staining was employed to examine apoptosis at 24 h after radiation. Radiation resulted in DNA condensation in H9c2 cells. Chromatin condensation, indicative of apoptosis, and apoptotic bodies were examined. Arrows indicate apoptotic nuclei and apoptotic bodies (10 × 20).
