Figure 2From: Concentration effects of grape seed extracts in anti-oral cancer cells involving differential apoptosis, oxidative stress, and DNA damageAnalysis on distribution of cell cycle in GSE-treated Ca9-22 cells. Ca9-22 cells were treated with indicated GSE concentrations (0–400 μg/ml) for 24 h before being harvested, fixed and stained with PI for cell cycle analysis. (A) Representative histograms for cell cycle phases in GSE-treated Ca9-22 cells. (B) Quantitative analysis on distribution of cell cycle phases. Data, mean ± SD (n = 3). Treatments with the same capital letter are nonsignificant.Back to article page
