| Research Abstract |
In head and neck cancers, elevated expression of RHAMM was associated with high proliferation of cancer cells. In addition, we demonstrated that there were two biologically different cancer stem cell (CSC) phenotypes of salivary gland carcinoma and oral squamous cell carcinoma, one of which is CD44high/ epithelial specific antigen (ESA) low cells, which have mesenchymal characteristics and are migratory, while the other phenotype is CD44high/ESAhigh cells, which have epithelial properties and high proliferative capacity, and harbor increased RHAMM expression. Since RHAMM is required for holoclone forming of CD44high/ESAhigh cells, it appears that it has a role in the self-renewal ability of head and neck CSC.
