Research Abstract |
SH2-containing inositol-5'-phosphatase(SHIP), which is related to immunoreaction, has been reported to negatively regulate the proliferation of osteoclast precursors induced by macrophage colony-stimulating factor(M-CSF) and ligand for receptor activator of nuclear factor kappa B(RANKL). In this study, we investigated the effects of SHIP on TNF-α-induced osteoclastogenesis. Bone marrow cells from SHIP+/+ and SHIP-/-mice were cultured with M-CSF and TNF-α. The number of TRAP-positive cells was significantly increased in SHIP-/-cells compared with SHIP+/+ cells. These results suggest that SHIP may negatively regulate the proliferation of osteoclast precursors.
