Effects of resveratrol on TGF-β2-induced collagen gel contraction in ARPE-19 cells.

Notes: (A) Cells were pretreated with or without resveratrol and then treated with TGF-β2 in the presence or absence of 50 or 100 µM resveratrol. (B) Contraction or expansion was determined as a percentage of the original area. The results are the mean values ± SEM of three independent experiments. ***P<0.001 versus the control group; ^##P<0.01; ^###P<0.001.

Abbreviations: NS, not significant; RES, resveratrol; SEM, standard error of the mean; TGF, transforming growth factor.
