hMSC-DP ameliorate Dextran sulfate sodium (DSS)-induced experimental colitis. a Body weights were recorded every day for 8 days in DPSCs and SHED transplanted groups. The relative alteration of body weight was calculated. n = 3 for each group. b Disease activity index (DAI) was evaluated on day 8 of DSS feeding. n = 3 for each group. c Colon length was measured on day 8. n = 3 for each group. d Histological score based on H&E staining images was assessed on day 8. The histological score of each group was calculated. n = 3 for each group. SE, serum; SF, serum-free. Data shown as mean ± SEM. Comparisons with untreated DSS group: ^#p < 0.05, ^##p < 0.01, ^###p < 0.001. NS not significantly different from DSS group. Comparisons of DPSCs or SHED at P5, P10 and P20: *p < 0.05, **p < 0.01, ***p < 0.001. ns not significant
