| Research Abstract |
The balloon endoscopy enables the collection of the biopsy specimen which reflected the entire small intestine environment in live. Therefore, we develop the differentiation mechanism of the intestinal epithelial cells to establish the assessment of whole small intestinal function in human. Then we finally aimed to consolidate a target of the treatment for small intestinal disease. In addition, I aimed to establish ex vivo culture of small intestinal epithelial cells to assess the function of the stem cells as a screening method.In this study, we compared the pathological findings between the patients with Crohn’s disease and healthy control. Interestingly, no change was shown in jejunum between the patients with Crohn’s disease and healthy control. However, comprehensive gene expression analysis with microarray showed the significant difference between the patients with Crohn’s disease and healthy control. Finally we identified specific genes in Japanese patients with Crohn’s disease.
