Fig. 4From: ERK-estrogen receptor α signaling plays a role in the process of bone marrow mesenchymal stem cell-derived exosomes protecting against ovariectomy-induced bone lossChanges in the cell cycle distribution of MG-63 cells co-cultured with BMSC-Exos. The cells were treated with 80 μg/ml BMSC-Exos for 12 to 72 h. Flow cytometric analysis was used to detect the cell cycle distribution. (n = 3 for each group. *P < 0.05 compared to the control.)Back to article page
