CM of SCC25 cells induces more differentiation of human osteoclasts. (A) Compared with the CD14+ monocytes cultured with cytokines CSF and RANKL, those cultured with CM of SCC25 cells yielded more osteoclasts on days 3 and 6 (arrow, TRAP). IF showed similar results, and greater numbers of F-actin rings were found in both groups on days 3 and 6 (arrow, F-actin). No osteoclasts were observed in the negative control group comprising CD14+ monocytes only. Representative photos of TRAP and F-actin staining of osteoclasts. (B) Quantification of osteoclasts and F-actin. Significant differences were found between these 4 groups (*P<0.05).
