Characterization of human ADSCs. a Isolated human ADSCs presented a fibroblast-like morphology under light field microscope. b Flow cytometry results show human ADSCs were positive for the MSC markers CD29 (97.7 %), CD44 (99.1 %), CD73 (99.7 %), and CD90 (98.8 %), and were negative for the hematopoietic stem cell markers CD31 (0.1 %), CD34 (1.6 %), and monocyte cell antigen CD14 (1.4 %). c, d Adipogenic and osteogenic differentiations were confirmed by Oil Red O and Alizarin Red S staining, respectively.
