Calcium (Ca) stimulates proliferation of osteoblasts in vitro, an effect proposed to be mediated by IGF I. Addition of 1 mM Ca or of 1 nM IGF I to the medium (0.3 mM Ca) of a rat bone-derived cell line, PyMS, stimulated not only DNA synthesis but als

1α,25-Dihydroxyvitamin D3 [1,25(OH)2D3] stimulate calcium and phosphate absorption in the duodenum. Because osteoblastic cells appear to be responsible for Pi deposition in bone, we analyzed the effect of 1,25(OH)2D3 on sodium-dependent phosphate (N

Osteoblasts prepared from calvaria of newborn rats produce insulin-like growth factors (IGF) and IGF-binding proteins (IGFBP), IGFBP-5 was discovered in bone extracts. However, we could not detect IGFBP-5 in the medium of newborn rat osteoblasts, alt

Osteoblast-like cells prepared from calvaria of newborn rats produce insulin-like growth factor (IGF) I and several insulin-like growth factor binding proteins (IGFBPs) in vitro. Among the IGFBPs found in conditioned cell culture medium, IGFBP-3 is t

Isolated cells produce insulin-like growth factors (IGFs) and their binding proteins (IGFBPs). Two distinct cell types were studied with regard to IGFBP-2 expression: (i) rat hepatocytes, which produce IGF I at a high rate and thus regulate its plasm

Eicosanoids are released by bone cells in response to physical, hormonal, and cytokine stimulation, and they can both inhibit and stimulate bone formation. We investigated the effect of PGE2 on sodium-dependent phosphate (Na(d)Pi) transport in a rat

IGFBP-3 and IGFBP-6 were used to study whether both IGF I and IGF II play a role in auto-/paracrine stimulation of rat osteoblast growth. Both IGFBPs decreased basal DNA synthesis in neonatal rat calvaria cells but with different potencies. Consisten
