| Outline of Final Research Achievements |
In this study, we examined the gene expression of interstitial cells of Cajal, which are thought to be the regulatory cells of gut motility, in trinitrobenzene sulfonic acid-induced experimental colitis of mice. We suggested that the proliferation of ICC and smooth muscle cells is involved in the recovery of organs on muscularis inflammation. By microarray, we found some candidate genes related to ICC recovery including cell growth factors and transcription factors. These results may lead to the development of new therapeutic strategy for motility disorder of gut.
