| Outline of Final Research Achievements |
The establishment of the in vitro carcinogenesis model enables the dynamic, chronological, and real-time analyses of the alimentary canal mucosa duct and is thought to be particularly important to the elucidation of the mechanism of "the cancerogenesis from chronic inflammation". It is important to perform the immunosuppressive treatment including anti-TNF-α antibodies for the refractory inflammatory bowel diseases (ulcerative colitis, Crohn's disease, intestinal Behcet's disease) in consideration of the history of treatment of the case and clinical course.

| Academic Significance and Societal Importance of the Research Achievements |
in vitro発癌モデルの確立により、in vivoの実験に用いる実験動物の数を最小限に留めることが可能となり、動物愛護の観点から社会的にも大変意義深い。また、抗TNF-α抗体製剤を含めた免疫抑制治療は高額になることが多く、これらの治療を適切に行うことが医療経済学上も重要である。
