Outline of Final Research Achievements |
Appropriate cancer cell models and animal experimental models that mimic cancer progression are required to analyze the metastasis of oral cancer cells, which occurs through complex steps. In this study, gene expression analysis was performed using HSC-3 cells and HSC-3-M3 cells and several genes related to prognosis were identified. In addition, chorioallantoic membrane assay was established as an animal experimental model. The tumors at the transplanted site could be histologically analyzed in detail using HE staining and immunohistochemical staining, and we have established the inexpensive and rapid analysis for gene expression and function.

Academic Significance and Societal Importance of the Research Achievements |
口腔癌の研究には様々な癌細胞株が利用されているが、各細胞株の特性・背景は異なっているため、解析結果を直接比較することが困難な場合も多い。本研究で用いたHSC-3細胞とHSC-3-M3細胞は同一患者の癌進展モデルとして有用と考えられた。また、本研究で確立した鶏卵漿尿膜移植法は、安価かつ迅速に癌進展を再現することができ、マウス実験に代わる(あるいはマウス実験の前段階で行う)動物実験と考えられた。
