Figure 1. Characterization of EVs. (A) Representative NTA showing particle concentration and size distribution of EVs isolated from plasma of HCC and NHCC patients pre- and post-MWA, compared with resuspension buffer (PBS filtered through a 0.02 µm filter) used for EV isolation; (B) Representative western blot of EV markers CD63 and CD9 in HCC and NHCC patients pre- and post-MWA. EV: Extracellular vesicle; HCC: hepatocellular carcinoma; MWA: microwave ablation; NHCC: non-HCC group (hepatic metastases of extrahepatic primary tumors); NTA: nanoparticle tracking analysis; PBS: phosphate-buffered saline.
