Effect of WEPN on actin ring of osteoclasts. (A) Osteoclasts were treated with or without WEPN for 1 h and then stained with phalloidin-TRITC (0.2 μg/mL, Sigma). Representative microscopic images of actin-ring were visualized using an inverted phase contrast fluorescence microscope. (B) Multinuclear cells (MNC) stained were counted.
