1 In resorbing calvariae and long bones with an established marrow cavity TGF-beta 1 (4-10 ng/ml) had a stimulating effect on 45Ca release that was partially inhibited by indomethacin. Indomethacin transforming growth factor, beta 1 Mus musculus
2 In primitive long bones, however, which were explanted before osteoclast invasion and excavation of a marrow cavity had started, TGF-beta 1 (1-4 ng/ml) inhibited 45Ca release by an indomethacin-insensitive mechanism. Indomethacin transforming growth factor, beta 1 Mus musculus
3 These data suggest that TGF-beta 1 modulates various steps in the cascade of osteoclast development, recruitment, and activation in different ways, involving both prostaglandin-mediated and prostaglandin-independent pathways. Prostaglandins transforming growth factor, beta 1 Mus musculus
4 These data suggest that TGF-beta 1 modulates various steps in the cascade of osteoclast development, recruitment, and activation in different ways, involving both prostaglandin-mediated and prostaglandin-independent pathways. Prostaglandins transforming growth factor, beta 1 Mus musculus
