Figure Lengend Snippet: In vitro antifibrotic effects of sEVs ErF on HSFs. (A, B) EdU staining and quantification of proliferating HSFs treated with Con, Er, sEVs Er , or sEVs ErF . Scale bar, 100 μm. (C) CCK-8 assay showing dose-dependent viability changes. (D, E) Transwell migration images and quantification of migrated HSFs. Scale bar, 100 μm. (F, G) Wound healing assay images and migration area (%) over time. Scale bar, 400 μm. (H-K) Western blot and densitometric analysis of COL I, COL III, and α-SMA; GAPDH, loading control. (L, M) α-SMA immunofluorescence and quantitative fluorescence intensity in HSFs. Scale bar, 50 μm. (N, O) Calcein-AM/PI flow cytometry and quantification of PI-positive cells. Data are mean ± SD; ∗p < 0.05, ∗∗p < 0.01, ∗∗∗p < 0.001, ∗∗∗∗p < 0.0001.
