In a previous study (Jeong et al., 2003, Inhibition of Drynariae Rhizoma extracts on bone resorption mediated by processing of cathepsin K in cultured mouse osteoclasts. International Immunopharmacology 3, 1685-1697), treatment of osteoclasts-containing long bone cells with Drynariae Rhizoma (DR) extract prevented the intracellular maturation of cathepsin K and thus, it was considered that DR is a pro-drug of a potent bone resorption inhibitor. To further clarify the role of DR in ossification, we investigated the effects of DR on the proliferation and differentiation of osteoblastic cell lines in vitro. In this study, the bone effect of DR is studied. We assessed the effects of DR on osteoblastic differentiation in nontransformed osteoblastic cells (MC3T3-E1) and rat bone marrow cells. DR enhanced alkaline phosphatase (ALP) activity and mineralization in a dose- and time-dependent fashion. This stimulatory effect of the DR was observed at relatively low doses (significant at 50-150 microg/ml and maximal at 150 microg/ml). Northern blot analysis showed that the DR (100 microg/ml) increased in bone morphogenetic protein-2 as well as ALP mRNA concentrations in MC3T3-E1 cells. DR (60 microg/ml) slightly increased in type I collagen mRNA abundance throughout the culture period, whereas it markedly inhibited the gene expression of collagenase-1 between days 15 and 20 of culture. These results indicate that DR has anabolic effects on bone through the promotion of osteoblastic differentiation, suggesting that it could be used for the treatment of common metabolic bone diseases such as osteoporosis.
