Fig. 3From: Protective effect of sildenafil on the genotoxicity and cytotoxicity in apolipoprotein E-deficient mice bone marrow cellsEffects of sildenafil treatment on cell cycle distribution in bone marrow cells from WT, apoE−/− and Sil mice. The cell cycle distribution was monitored via PI staining and flow cytometric analysis. Statistical analysis of the percentage of cells in sub-G0-phase (a), G0/G1-phase (b), S-phase (c) and G2/M-phase (d). The values are the means ± SEM. *p < 0.05 vs. WT group; # p < 0.05 vs. apoE−/− group (one-way ANOVA)Back to article page
