Fig. 1From: The BMP signaling pathway enhances the osteoblastic differentiation of bone marrow mesenchymal stem cells in rats with osteoporosisComparison on weights and BMD of rats in OP model group and normal group. Note: a, weights of rats in OP model group and normal group; b, BMD of rats in OP model group and normal group. **Compared with rats in normal group, P < 0.01; OP, osteoporosis; BMD, bone mineral density; rBMSCs, rat bone marrow mesenchymal stem cells; OP, osteoporosisBack to article page
