Increased levels of reactive oxygen species (ROS) are a crucial pathogenic factor of osteoporosis. Gastrodin, isolated from the traditional Chinese herbal agent Gastrodia elata, is a potent antioxidant. We hypothesized that gastrodin demonstrates protective effects against osteoporosis by partially reducing reactive oxygen species in human bone marrow mesenchymal stem cells (hBMMSCs) and a macrophage cell line (RAW264.7 cells). We investigated gastrodin on osteogenic and adipogenic differentiation under oxidative stress in hBMMSCs. We also tested gastrodin on osteoclastic differentiation in RAW264.7 cells. Hydrogen peroxide (H2O2) was used to establish an oxidative cell injury model. Our results showed that gastrodin significantly promoted the proliferation of hBMMSCs, improved some osteogenic markers, reduced lipid generation and inhibited the mRNA expression of several adipogenic genes in hBMMSCs. Moreover, gastrodin reduced the number of osteoclasts, TRAP activity and the expression of osteoclast-specific genes in RAW264.7 cells. Gastrodin suppressed the production of reactive oxygen species in both hBMMSCs and RAW264.7 cells. In vivo, we established a murine ovariectomized (OVX) osteoporosis model. Our data revealed that gastrodin treatment reduced the activity of serum bone degradation markers, such as CTX-1 and TRAP. Importantly, it ameliorated the micro-architecture of trabecular bones. Gastrodin decreased osteoclast numbers in vivo by TRAP staining. To conclude, these results indicated that gastrodin shows protective effects against osteoporosis linking to a reduction in reactive oxygen species, suggesting that gastrodin may be useful in the prevention and treatment of osteoporosis.
