Fabrication of three types of exosomes: BMSC-Exos, BMSC-Fe3O4-Exos and BMSC-Fe3O4-SMF-Exos. (*) p < 0.05, (***) p < 0.001. a Schematic illustration of magnetic stimulation using Fe3O4 nanoparticles and SMF. b CCK8 assay for the proliferation of BMSCs cultured in the presence of various concentrations of Fe3O4 nanoparticles combined with exposure to SMFs of different strengths. c Proliferation of BMSCs treated with the optimal working concentration (50 µg/mL) of Fe3O4 nanoparticles and exposed to SMFs of different strengths. d TEM images of the Fe3O4 and BMSCs. The dotted yellow box indicates the internalization of Fe3O4 by BMSCs, and the red arrows indicate the Fe3O4 nanoparticles
