MiR-542-3p can be packaged into MSC exosomes. a MiR-542-3p was transfected into MSCs, and the expression of miR-542-3p was determined. Exosomes in supernatant were isolated, and b TEM was used to show the morphology of exosomes. c Particle size analysis showed the size of exosomes. d Exosome markers (CD63 and CD9) and MSC marker (GM130) were detected using western blot. e The expression of miR-542-3p in isolated exosomes was determined. Data are mean ± SD; **P < 0.01. All experiments were repeated in triplicate
