Exosomes (EXO) from activated human TWNT4 HSCs were added to culture medium of HL-60 macrophages for 48 hours. In parallel, TWNT4 HSCs were exposed to vehicle (V; 0.1% (v/v) FBS), 10% (v/v) FBS, IL-6 (1μg/mL), TNF-α (1μg/mL) or IL-6 (1μg/mL) +TNF-α (1μg/mL). A) Representative micrographs of transwell membranes following crystal violet staining. B) Quantification of
migration data following cell solubilization and measurement of absorbance at λ = 592nm). *P<0.05 versus V, n=4 independent experiments.
