Primary culture of BMSCs and identification. (A) The morphology of BMSCs from passage 1 to passage 3 was observed under the microscope. (B) The expression rates of CD90, CD44, CD45, and CD34 were detected by flow cytometry. (C) The osteogenic differentiation capability of BMSCs was assessed by alizarin red staining. (D) The adipogenic differentiation capability of BMSCs was assessed by Oil Red-O-staining. The results displayed were obtained from at least three independent experiments.
