POL-P3b induced the proliferation and inhibited apoptosis of intestinal DC by oral administration a The cell viability was evaluated by MTT assay. Data are mean values of triplicate assays ±SD, compared with control, ^☆P < 0.01; compared with model, ^●P < 0.05, P < 0.01. b Annexin V-FITC/PI staining was used to analyze apoptosis. c Representative results and summative data from three independent experiments were shown. Each bar represents means ± SD (n = 3). compared with control, ^☆P < 0.01; compared with model, ^●P < 0.05, P < 0.01. d Intestinal DCs isolated from mice treated with POL-P3b (50 mg/kg,100 mg/kg and 200 mg/kg, respectively) for 12 d were stained with Hoechst 33342 (blue)
