Antiosteoclastogenic effect of CDR and SrR by TRAP staining assay. (a) CDR or SrR alone, and control is 0 μg/ml; (b) cotreatment of CDR (200 or 400 μg/ml) with varying concentrations of SrR, and control (Ctrl) is the cells incubated with medium without drug (CDR and SrR). Data are expressed as mean ± SD (error bar). ^∗p < 0.05, ^∗∗p < 0.01, ^∗∗∗p < 0.001 versus control. The horizontal straight line indicates the groups beneath sharing the same statistical significance.
