Control group: the mice fed with normal water; PBS group, the mice were drinking water containing 2% DSS and intravenously treated with PBS on day 2. ( B ) The DAI was evaluated daily. Each point represents the average DAI data pooled from eight mice. ( C ) Appearance and statistical analysis of colon length on day 9. ( D ) Representative H&E staining of the colon mice of different groups. ( E-F ) Weight loss and DAI in mice transferred with PSI-CD69 + iTregs and Control-CD69 + iTregs. ( G-H ) The length of colon and H&E staining of the colon from mice from the different groups. Representative images of the data expressed as the mean ± SD of three independent experiments. * p < 0.05, ** p < 0.01, *** p < 0.001, **** p < 0.001, ns, not significant. ANOVA or Student's t -test was used to determine the significance.
