| Outline of Final Research Achievements |
We previously reported that SPARC plays important roles in the development and progression of oral squamous cell carcinoma (OSCC) through avoidance from exclusion of loser cells at cell competition. In this study, we examined the involvement of SPARC in malignant potentials of OSCC. Transfection of SPARC expression vector into OSCC cells and the immortalized oral mucosal epithelial cells resulted in enhanced proliferative capacity and exclusion of control cells in the co-culture system of SPARC overexpressed cells and control cells. On the other hands, the ability of adhesion, invasion, and migration were not affected, suggesting that SPARC may not be involved in malignant potentials of OSCC.
