Characterization of exosomes derived from apoptotic SHED. Particle size distribution of exosomes from normal SHED (A) and apoptotic SHED (B) evaluated via nanoparticle tracking. Morphology of exosomes from normal SHED (C) and apoptotic SHED (D) observed under a transmission electron microscope. Scale bar = 200 nm. Surface markers of exosomes (CD9, CD63, and CD81) analyzed via flow cytometry (E). Efficient uptake of PKH67-labeled exosomes (green) from normal SHED (F) and apoptotic SHED (G) by HUVECs detected in 4 h; the nuclei were counterstained with DAPI (blue). Scale bars = 100 μm.
