Promoting Osteogenic Differentiation of Human Adipose-Derived Stem Cells by Altering the Expression of Exosomal miRNA

Characterization of ADSCs (P3). (a) The expression of the characteristic surface markers of ADSCs shown by flow cytometry. (b) Lipid droplets formed after 14 days of adipogenic induction, which is confirmed by oil red O staining. (c) Calcium nodules formed during osteogenic differentiation, which is identified by ARS after 28 days of osteogenic induction. (d) The chondrocytes stained by alcian blue after 28 days of chondrogenic induction. Notes: ADSCs: human adipose-derived stem cells; ARS: alizarin red S. Scale bar: 100 μm.
