Fig. 1From: ERK-estrogen receptor α signaling plays a role in the process of bone marrow mesenchymal stem cell-derived exosomes protecting against ovariectomy-induced bone lossCharacterizations of bone marrow stem cells (BMSCs) and exosomes derived from BMSCs. A Light microscopy images demonstrating the typical fibroblast-like morphology of BMSCs. Scale bar. 200 μm. B Representative images of the tri-lineage differentiation capacity of BMSCs. Scale bars. 200 μm (left); 100 μm (middle); 50 μm (right). C Flow cytometric analysis of BMSC surface markersBack to article page
