Figure 1: Blueberry polyphenolic enriched extract alters the proliferation of HepG2 cells. Cells were treated with vehicle or 6.25-100 μg/mL polyphenolic enriched extract for 96 h and absorbance was measured at 490 nm using a proliferation MTS assay. Data are reported as mean ± SEM for n=6 independent experiments (for each time point and each dose, respectively). Values that do not share the same letters are significantly different from each other (p<0.001, by Tukey’s test).
