Differentiation abilities of ADMSCs and the identification of exosomes. Note: (a) ADMSCs stained with alizarin red after the osteoinductive differentiation; (b) ADMSCs stained with Oil Red O after the adipogenic differentiation; (c) Exosome protein expression detected by western blotting; (d) Exosome structure under the transmission electron microscopy (50 000 ×); ADMSC, adipose-derived mesenchymal stem cells.
