Inhibitory effect of polyphyllin VII (PP7) on the resorption capability of osteoclasts. Panel a Image of resorption lacunae under light microscope. The resorption lacunae assay in the presence of various concentrations of polyphyllin VII (PP7) was performed as described in the methods. Panel b Average areas of resorption lacunae per well in the presence of various concentrations of polyphyllin VII (PP7). Vertical axis: pixel dimensions; horizontal axis: polyphyllin VII (PP7) concentrations (μM). * P < 0.05 as compared with the group treated with 0 μM of polyphyllin VII (PP7); the dotted line represents a regression line
