Fig. 1From: Exosomes derived from HCC cells induce sorafenib resistance in hepatocellular carcinoma both in vivo and in vitroCharacterization of exosomes derived from different cell lines. a TEM confirmed that the final pellets from ultracentrifugation were exosomes (scale bar, 100 nm). b Size distribution analysis of purified exosomes by DLS (Nano-ZS90, Malvern). c Exosomal markers (CD9, CD63) were analyzed using Western blotting and are present in cells and exosomes (GAPDH was used as an internal reference)Back to article page
