The proliferation and proangiogenic effects of Exos and DFO-Exos on HUVECs. (a) Proliferation of HUVECs treated with Exos or DFO-Exos at 50 μg/mL concentration or an equal volume of PBS. P < 0.001 versus control, ^### P < 0.001 versus Exos group. (b) Left panel, representative images of transwell assay, scale bar = 200 μm; right panel, quantitative analysis of the assay. P < 0.001 versus control, ^### P < 0.001 versus Exos group. (c) Left panel, representative images of tube formation assay from three groups, scale bar = 200 μm; right panel, quantitative analysis of the assay. P < 0.001 versus control, ^### P < 0.001 versus Exos group.
