The results indicated that effects of Gd on the proliferation, osteogenic differentiation, mineralization function and adipocytic transdifferentiation of primary OBs de- pended on concentration and incubation time, but were not dose-dependent. It was suggested that the effect of Gd on bone metabolism was complicated, and concentration and culture time were key factors for switching the biological effects of Gd from damage to protection.展开更多
