Figure 1. (A) The size and morphology of exosomes derived from HUC-MSCs were determined using transmission electron microscopy (TEM). (B) The size distribution of exosomes derived from HUC-MSCs was scattered and identified using DLS. (C) The surface biomarkers Alixs, CD9 and CD63 were detected using western blot to identify exosomes derived from HUC-MSCs. (D) The exosomes derived from HUC-MSCs were labeled with PKH26.
