Analysis of cardiomyocytes apoptosis. Cardiomyocytes apoptosis detected by TUNEL method. (A) TUNEL staining pictures, in which brown stained cells were TUNEL positive cells, which were defined as "apoptotic". Magnification at 400×, scale bar is 100 μm. (B) Statistical analysis of Cardiomyocytes apoptosis. TUNEL positive cells were increased in Diabetes, and decreased by NRG-1 (n = 8, * P < 0.05 vs. control group; # P < 0.05 vs. Diabetic group.)
