Ginsenoside Rb1 Modulates the Migration of Bone-Derived Mesenchymal Stem Cells through the SDF-1/CXCR4 Axis and PI3K/Akt Pathway

Figure 1

The morphology, multilineage differentiation, and surface molecules expression of BMSCs. (a) BMSCs of passage 1: cells tended to be uniform with typical fibroblast-like morphology. (b) BMSCs were incubated with adipogenic induction medium, and the cells were positively stained by Oil Red O. (c) BMSCs were incubated with chondrogenic induction medium, and the samples were positively stained by Alcian blue. (d) BMSCs were incubated with an osteogenic induction medium, and calcium deposits were noted by Von Kossa. (e–h) The surface molecules expression of BMSCs showed expression of CD29, CD90, and CD105 whilst lacking CD34 (red solid line). The isotype antibodies were used as negative controls (blue dotted line).
