The influence V. opulus extracts on the accumulation of lipid droplets in MIN6 cells stained with Nile red observed after treating cells with the extracts at IC₀ for 24 h (A); as a positive control, 100 μM oleic acid was used; control cells were not exposed to any compound but the vehicle; values are means ± standard deviations from at least three independent experiments, n ≥ 12; statistical significance was calculated versus control cells ** p ≤ 0.01. Cells visualized under fluorescent microscope (200 × magnification) (B).
