Equol promotes rat osteoblast proliferation and differentiation through activating estrogen receptor

J. Wang, Xu, J., Wang, B., Shu, F. R., Chen, K., and Mi, M. T., Equol promotes rat osteoblast proliferation and differentiation through activating estrogen receptor, vol. 13, pp. 5055-5063, 2014.

Phytoestrogens have been suggested as alternative treatment for postmenopausal osteoporosis. Equol, a metabolite of daidzein, has been shown to inhibit bone loss in ovariectomized mice and rats. However, whether or not equol influences the formation of bone has not yet been investigated. Therefore, we investigated the effect of equol on the proliferation and differentiation of rat primary osteoblasts and explored the involved mechanisms. Different equol concentrations significantly promoted the proliferation of osteoblasts after 48- and 72-h incubations.

Effects of rifampicin on osteogenic differentiation and proliferation of human mesenchymal stem cells in the bone marrow

Z. Zhang, Wang, X., Luo, F., Yang, H., Hou, T., Zhou, Q., Dai, F., He, Q., and Xu, J., Effects of rifampicin on osteogenic differentiation and proliferation of human mesenchymal stem cells in the bone marrow, vol. 13, pp. 6398-6410, 2014.

This study was designed to investigate the effect of different concentrations of rifampicin on osteogenic differentiation and proliferation of mesenchymal stem cells (MSCs) in human bone marrow. Rifampicin treatment at 0, 4, 8, 16, 32, 64, and 128 mg/mL was applied throughout the whole process, from stromal cells purified from human bone marrow to differentiated bone cells. The effect of rifampicin on MSC proliferation was determined using the MTT assay.
