| Research Abstract |
Combination of RANKL, M-CSF and CCN2 significantly enhanced tartrate-resistant acid phosphatase (TRAP)-positive multinucleated cell formation compared with RANKL and M-CSF. Therefore, we suspected the involvement of CCN2 in cell-cell fusion during osteoclastogenesis. To clarify the mechanism, we isolated fetal liver cells from Ccn2-null mice at E14.5 days, and investigated TRAP-positive multinucleated cell formation. The results showed that RANKL-induced osteoclastogenesis was impaired in fetal liver cells from Ccn2-null mice, and the impaired osteoclast formation was rescued by the addition of exogenous CCN2. These results suggest that CCN2 involves in cell-cell fusion during osteoclastogenesis.
