In Vitro Protective Effects of Lycium barbarum Berries Cultivated in Umbria (Italy) on Human Hepatocellular Carcinoma Cells

Figure 2

Effect of LBB extract on cell viability. HepG2 cells are treated for 24 h with different concentrations of LBBs (from 400 μg/mL to 2800 μg/mL). Cell viability is measured by MTT assay (A) and by Trypan blue exclusion assay (B). The values are reported as % viability of the control sample set at 100%. Data are expressed as mean ± SD of four independent experiments ().
