The expression of Atoh1 in the MSCT group was significantly higher than in the MSC (1.34±0.27 versus 0.95±0.08, P = 0.011), normal (1.34±0.27 versus 0.91±0.15, P = 0.004), or IBD rat models (1.34±0.27 versus 0.99±0.48, P = 0.007) (there were no significant differences among these three groups). The gene discussed is ATOH1; the disease is inflammatory bowel disease.
