Characterizations of human adipose-derived mesenchymal stromal cells (hADMSCs). a Morphological features of the fourth-passage hADMSCs under light microscopy (× 100 magnification, scale bar =75 μm). b Representative images of Oil Red O staining (left: non-induced control group; right: induced group; × 200 magnification, scale bar = 75 μm). c Representative images of the alkaline phosphatase calcium cobalt staining (left: non-induced control group; right: induced group; × 200 magnification, scale bar =75 μm). d Flow cytometry analysis of cell surface marker CD29, CD90, CD31, and CD45 was showed in hADMSCs
