Characterization of normal and DM human LSC-derived Exos. (a) Representative TEM images showing a range of exosomal size from 50–200 nm and typical doughnut shape morphology in both N (n = 3) and DM (n = 3) human LSC-derived Exos. (b) size distribution of LSC-derived EVs was determined by NanoSight LM10. Histogram shows particle size distribution typical of exosomes. (c) Flow cytometry was performed on normal (healthy)- and DM-EVs using anti-CD63-coated beads. Vesicles were immunostained against CD63 (red) and CD81 (red) and compared with appropriate isotype control (blue), n = 3. (d) Western blot showed expression of typical exosomal markers HSP70 and CD63 in both N (n = 3) and DM (n = 3) vesicles.
