Antioxidant Effect of Beer Polyphenols and Their Bioavailability in Dental-Derived Stem Cells (D-dSCs) and Human Intestinal Epithelial Lines (Caco-2) Cells

Figure 4

Antisenescent effect of beer fractions on D-dSCs and Caco-2 cells. Senescence-associated beta-galactosidase (SA-β-Gal) was detected. (a) D-dSCs; (b) Caco-2, percentage of cellular senescence in not-injured cells treated with beer fractions solution: must (must), prehopping solution (pre-h), and posthopping solution (post-h). (c) D-dSCs; (d) Caco-2, percentage of cellular senescence in H₂O₂-injured cells treated with beer fractions solution: must (must), prehopping solution (pre-h), and posthopping solution (post-h). Data is shown as the percentages of β-galactosidase-positive cells with respect to the total cell number of the sample. Each bar represents the of three replicates from three independent experiments. versus the control (Ctr, cells not injured); ^°° versus the H₂O₂; ^° versus the H₂O₂.
