Fig. 3From: Icotinib-resistant HCC827 cells produce exosomes with mRNA MET oncogenes and mediate the migration and invasion of NSCLCCharacterization of exosomes from HCC827IR cell-derived exosomes. a The size distribution analysis of purified exosomes by DLS. b The transmission electron microscopic image of the HCC827IR cell-derived exosomes. Scale bar, 20 nm. c Exosome-specific markers CD9, CD81 and CD63 were detected using western blot analysis. The exosome-depleted supernatant (EDS) used as the control group. d The internalization of HCC827IR cell-derived exosomes in HCC827 cells. The derived HCC827IR cellsBack to article page
