| Outline of Final Research Achievements |
There are different modes of invasion in the process of cancer spread. One is expansive invasion, in which a group of cancer cells gradually expands along with cancer cell proliferation. The other is a more extensive invasion promoted by interactions with stromal cells, including cancer associated fibroblasts (CAF). In the present study, it was shown that CAF induces a certain number of apoptosis in gastric cancer cells, which prevents the cancer-expansive invasion, and instead promotes CAF-led widespread invasion.

| Academic Significance and Societal Importance of the Research Achievements |
圧排性増殖型の浸潤癌は癌患部の切除によって根治可能である。一方、播種型浸潤の癌における予後は良くない。これらの浸潤型の選択メカニズムは不明であった。本研究では、世界に先駆けてこのメカニズムに注目し、その成果を論文報告した。今後、播種性浸潤の抑制に繋がる研究を進め、癌治療へ繋げることを目指している。
