Cytotoxicity of embelin toward primary porcine brain endothelial cells (PBECs), tested using the MTT assay. Untreated cells were used as a control to represent total viable cells. The cells were also treated with 1% (v/v) methanol in culture medium as vehicle control. Data are mean ± SD from 3 independent experiments (n = 3) with 3 replicates for each experiment. * P < 0.05 ** P < 0.01, as tested using One-way ANOVA.
