Characterization of exosomes. (a) Viability assay of BMSCs treated with various concentrations of DFO for 48 hours. DFO-treated BMSCs at 100 and 200 μM concentration showed significantly more viability when compared to control group. P < 0.001 versus control. (b) Western blotting showed the presence of exosomal markers including CD9, CD63, and TSG101 in Exos and DFO-Exos. (c) qNano analysis results of Exos and DFO-Exos. (d) TEM photomicrographs of Exos and DFO-Exos. Scale bar = 50 nm.
