A Morphology of HucMSC-Exo detected by electron microscopy. B Western blot detection of exosome-related markers in HucMSC-Exo and MSC. C HucMSC-Exo nanoparticle size analysis detected by Particle Metrix’ ZetaView; particles were mainly enriched at 128.7 nm. D HK-2 cell uptake of HucMSC-Exo labeled by PKH-26Back to article page
