Identification of ADSCs. A. Representative phase image of passage 3 ADSCs that exhibited spindle-like morphology. B. Flow cytometry analysis of ADSCs that were positive for CD29, CD44, CD90, and CD105 and negative for CD31, CD34, and CD45. C. Alizarin red staining confirmed osteogenic induction of ADSCs. D. Adipogenesis of ADSCs was confirmed by Oil Red-O staining that indicated the production of lipid droplets. E. Alcian blue staining confirmed chondrogenic induction of ADSCs. Scale bar = 100 μm.
