    Abstract:
    Nutritional and pharmacological factors are needed to prevent bone loss that occurs with increasing age. The chemical compounds that act on bone metabolism as nutrients in food, however, are poorly understood. The effect of resveratrol, a natural phytoestrogen, on the proliferation and differentiation of osteoblastic MC3T3-E1 cells was studied. Resveratrol dose-dependently increased DNA synthesis (10(-9)-10(-7) M) of MC3T3-E1 cells. In addition, resveratrol increased alkaline phosphatase (ALP) activity and prolyl hydroxylase activity of MC3T3-E1 cells (10(-6)-10(-5) M). Moreover, the antiestrogen tamoxifen eliminated the stimulation of MC3T3-E1 cells on the proliferation and ALP activity by resveratrol. On the other hand, resveratrol inhibited prostaglandin E2 production in MC3T3-E1 cells (10(-8)-10(-6) M). Our present study is the first to demonstrate that resveratrol directly stimulates cell proliferation and differentiation of osteoblasts.
