Fig. 6From: Effect of gut microbiome-derived metabolites and extracellular vesicles on hepatocyte functions in a gut-liver axis chipCharacterization of microbiota-derived extracellular vesicles. A Size distribution analysis of exosome-enriched EV samples analyzed by TRPS system. B Percentage of viable cells, measured as LDH release, after treatment with various concentrations of EVs (0.1 × 109 to 10 × 109 particles/mL), Data are represented as the mean ± SEM of four independent experiments. *p < 0.05 for control vs. each groupBack to article page
