Fig. 2From: Gene expression profiling analysis to investigate the role of remote ischemic postconditioning in ischemia-reperfusion injury in ratsCardiomyocyte apoptosis analysis by TUNEL assay. a A TUNEL assay was performed to analyze the effect of RPostC treatment on the level of apoptosis in cardiomyocytes. Bar = 100 μm. b The percentage of TUNEL-positive cells was determined and analyzed by ANOVA-LSD test. Significant difference was indicated: **, P < 0.01Back to article page
