大学院生の研究教育内容と指導実績

(1)研究教育内容

大学院は、より良き医師となるための医学、医療の教育の場であると同時に、将来に役立つ科学的探究心を養う場でもあります。特に、研究を通して科学者の心を養うことは、今後の医師としての歩みの土台となります。医学博士は、医師の経歴の一つとしても大変大事なものですが、そのためには研究テーマに基づく学位論文を作成する必要があります。当科では、基礎と臨床を繋ぐTranslational researchの視点から、最先端の技術を用い、主に癌の診断と治療に関して以下のテーマで研究を行っています。

1.癌微小転移の遺伝子診断法の開発
2.癌幹細胞のプロファイル解析と癌治療への応用
3.microRNA発現と転移カスケードの解析
4. 癌の化学療法、分子標的薬、放射線療法における治療効果予測法の開発
5.癌免疫療法の開発
6.iPS細胞を用いた再生医療

(2)大学院生指導実績

これまで外科学講座大学院生24名の学位指導をさせていただき、全員が医学博士を取得しています。このうち13名の学位論文が英文国際誌に掲載され、3名が学会奨励賞を受賞しています。

研究室紹介

当科には研究専任スタッフ、飯沼久恵(講師)と田村純子(研究助手)がおります。研究に必要な実験手技、研究の進め方、論文作成など、卒業時までに学位がとれるよう、大学院生の皆様の研究を全面的にサポートします。外科研究室は、今年(平成24年)4月に完成した、新大学棟の8階にあります。非常に綺麗なスペースで、最先端の実験機器が揃ったすばらしい研究環境が用意されています(写真1,2,3)。
