Antiadipogenesis effect on 3T3-L1 of SV extracts collected from different regions. (a) Effect of SV extracts at 10 and 50 μg/ml on viabilities of 3T3-L1 cells determined by MTS assay for 24 h; (b) relative lipid content, quantified by absorbance in 3T3-L1 cells with or without SV extracts at 10 and 50 μg/mL for 8 days; (c) Oil Red O staining of lipid droplets in 3T3-L1 cells with or without SV extracts at 10 and 50 μg/mL for 8 days. Results are presented mean ± SE. The asterisk indicates a significant difference compared to DM ( and ).
