| Outline of Final Research Achievements |
Cancer stem cells are attracting attention as a factor showing chemoradiotherapy resistance of cancer tissue, but in recent years cancer cells have acquired cancer stem cell-like properties by causing epithelial mesenchymal transition (EMT). It is pointed out that the metastatic potential may be enhanced. We induced EMT by introducing snail into oral cancer cell line HSC4 and confirmed that the expression level of mRNA of stem cell markers in the cell line increases. These findings suggested that induction of EMT in oral cancer cell lines would acquire cancer stem cell-like properties.
