Fig. 3From: ERK-estrogen receptor α signaling plays a role in the process of bone marrow mesenchymal stem cell-derived exosomes protecting against ovariectomy-induced bone lossResponses of MG-63 cells co-cultured with BMSC-Exos. A Proliferation of MG-63 cells was detected by CCK-8 assay. B, C Differentiation of MG-63 cells was detected by ALP test kit. Scale bar: 100 μm. D, E. Mineralized nodules in MG-63 cells were detected by Alizarin red S staining. Scale bar: 100 μm. (n = 3 for each group. *P < 0.05 compared to the control. **P < 0.01 compared to the control.)Back to article page
