| Outline of Final Research Achievements |
Apoptotic oral squamous cell carcinoma (SCC) cells are engulfed by macrophages or even by neighboring SCC cells. We hypothesized that engulfment of apoptotic carcinoma cells by living carcinoma cells are promoted via MFG-E8, one of phagocytosis regulating molecules, and this phenomenon could contribute to tumor progression. Transient MFG-E8 overexpression in SCC cell lines increased migration, invasiveness, and engulfment of apoptotic cells. Thus we have demonstrated that MFG-E8 is involved in the clearance of apoptotic carcinoma cells by living carcinoma cells, and it might promote tumor progression in oral SCC.
