Figure 3.Exogenous H2S decreases the apoptotic rate and increases cell viability in the aged H9C2 cells. (A) Apoptosis was analysed by flow cytometry. The apoptotic rate = early apoptotic rate + late apoptotic rate. All data were from four independent experiments. (B) Cell viability measured using a CCK-8 kit. The viability of control cells was considered 100%, and the others were expressed as percentages of control. All data are the means ± S.E.M. of 8 determinations. * p<0.05 vs. control group; # p<0.05 vs. H/R group; & p<0.05 vs. PC group; § p<0.05 vs. H/R + NaHS group; $ p<0.05 vs. PC + NaHS group.
