| Outline of Final Research Achievements |
Using our methods for preparing and culturing primary 3D cancer cells, in which 3D structure in the tumor is preserved, we demonstrated that apico-basal polarity switches depending on culture conditions and clarified the role of polarity switching in metastasis. In addition, we revealed that micropapillary carcinoma, a pathological pattern with poor prognosis, is a polarity unswitchable status, and clarified the underlying molecular mechanisms.

| Academic Significance and Societal Importance of the Research Achievements |
本研究では、極性転換ががんの病態に深く関与していることを明らかにした。特に、予後不良の組織型であるmicropapillary carcinomaの病態とその分子メカニズムを明らかにすることができたことは意義深い。がんの転移能を極性転換能からアプローチした研究はこれまでになく、本研究成果はがんの進展・転移の制御による新たな診断・治療法の発展につながることが期待できる。
