Combined treatment with PL and ZA synergistically inhibits cancer-induced osteoclastogenesis in vitro. (Aa) BMMs were treated with various concentrations of individual or combined PL and ZA plus RANKL for 5 days. TRAcP staining to elucidate osteoclast formation was performed in vitro. (b) The number and percentage of TRAcP-positive MNCs in the individual drug groups and the combination groups. (Ba) hPBMCs were treated with CM from MDA-MB-231 cells containing various concentrations of individual or combined PL and ZA for 21 days. TRAcP staining to elucidate osteoclast formation was performed in vitro. (b) The number and percentage of TRAcP-positive MNCs in the individual drug groups and the combination groups. The data are presented as the means±S.D. All experiments were repeated at least three times. Scale bar=250 μm (*significant difference at P<0.1; **significant difference at P<0.05)
