1 At low concentrations (10-100 pg/ml) TGF beta enhanced 1,25-dihydroxyvitamin D3-dependent production of osteoclast-like cells, while at higher concentrations TGF beta was inhibitory. Calcitriol transforming growth factor, beta 1 Mus musculus
2 Antibodies directed against TGF beta significantly reduced the generation of osteoclast-like cells in 1,25-dihydroxyvitamin D3-treated cultures, indicating the contribution of endogenous TGF beta activity. Calcitriol transforming growth factor, beta 1 Mus musculus
3 Antibodies directed against TGF beta significantly reduced the generation of osteoclast-like cells in 1,25-dihydroxyvitamin D3-treated cultures, indicating the contribution of endogenous TGF beta activity. Calcitriol transforming growth factor, beta 1 Mus musculus
4 TGF beta also enhanced the accumulation of prostaglandin E2 (PGE2) in a dose-dependent manner. Dinoprostone transforming growth factor, beta 1 Mus musculus
5 TGF beta also enhanced the accumulation of prostaglandin E2 (PGE2) in a dose-dependent manner. Dinoprostone transforming growth factor, beta 1 Mus musculus
6 It is, thus, suggested that PG activity, probably PGE2, mediates the enhancing effect of low TGF beta concentrations and is required for the generation of osteoclast-like cells in this system. Prostaglandins transforming growth factor, beta 1 Mus musculus
7 It is, thus, suggested that PG activity, probably PGE2, mediates the enhancing effect of low TGF beta concentrations and is required for the generation of osteoclast-like cells in this system. Dinoprostone transforming growth factor, beta 1 Mus musculus
