Identification of serum exosomes. (A) Serum exosomes were observed by transmission electron microscopy (TEM) (scale bar = 500 nm); (B) Size distribution of serum exosomes was detected by dynamic light scattering (DLS), and the size of serum exosomes was 105 ± 11.25 nm; (C) The expression of TSG101, CD63 and ALIX in serum exosomes from three groups were detected by western blot.
