ジャーナル Biochem Biophys Res Commun
Abstract Basic fibroblast growth factor (bFGF) inhibited osteoclast-like cell (OCL) formation in cocultures of mouse spleen cells with either osteoblasts or a stromal cell line, ST2, in the presence of 1alpha, 25-dihydroxyvitamin D(3) [1,25(OH)(2)D(3)]. bFGF directly acted on osteoblasts/stromal cells, but not osteoclast progenitors, to inhibit 1,25(OH)(2)D(3)-induced OCL formation. bFGF suppressed the mRNA expression of osteoclast differentiation factor (ODF) but did not affect that of osteoclastogenesis inhibitory factor (OCIF) in ST2 cells treated with 1,25(OH)(2)D(3) and dexamethasone. Enzyme-linked immunosorbent assay showed that bFGF hardly affected OCIF production in the treated ST2 cells. A genetically engineered soluble form of ODF, but not anti-OCIF neutralizing antibody, abolished bFGF-mediated inhibition of OCL formation. bFGF suppressed the binding of (125)I-labeled OCIF to both ST2 cells and osteoblasts treated with 1,25(OH)(2)D(3). These findings indicate that bFGF inhibits 1,25(OH)(2)D(3)-induced OCL formation via suppression of ODF production by osteoblasts/stromal cells.
