Characterization of hADSCs and hADSCs-Exos. a Microscopic images of hADSCs. Scale bar = 20 μm. b hADSCs differentiated into adipocytes—Oil Red O (red), osteoblasts – RunX2 (red), and chondrocytes—alcian blue (blue). c Detection of the specific markers of hADSCs by flow cytometry illustrated that hADSCs were positive for CD73, CD90, and CD105, negative for HLA-DR and CD45. d hADSCs- Exos Ultracentrifugation extraction. hADSCs-Exos were identified by electron microscope (e), NanoSight (f), and Western blot (g)
