Fig. 1From: Human umbilical cord mesenchymal stem cell-derived exosomal miR-335-5p attenuates the inflammation and tubular epithelial–myofibroblast transdifferentiation of renal tubular epithelial cells by reducing ADAM19 protein levelsIdentification of human umbilical cord mesenchymal stem cell (hucMSC)-exosomes. A hucMSC-exosomes were identified by transmission electron microscopy. B The size distribution of hucMSC-exosomes was measured by Nanoparticle Tracking Analysis. C CD81 and β-actin in hucMSC-exosomes were measured via western blotting (n = 3)Back to article page
