Outline of Final Research Achievements

We researched suicide gene therapy to the malignant brain tumor which has difficulty in treatment, using adipose mesenchymal stem cell(ADMSC)/ganciclovir(GCV). First mesenchymal stem cell was separated from a SD rat fat cell. Treatment was tried using ADMSC which introduced herpes simplex virus-thymidine kinase(ADMSCtk) to a rat C6 brain tumor cell. In vitro, the cell ratio of ADMSCtk:C6 also indicated anti-tumor effect in 1:8. In vivo, the tumor volume reduction effect and the extension of a survival curve were confirmed by a study using a rat. ADMSCtk/GCV treatment will be effective.

Academic Significance and Societal Importance of the Research Achievements

今まで我々は一貫して、自殺遺伝子療法を用いた脳腫瘍の治療研究にあたってきた。その中で、安定的に供給できるベクターの選択が問題であった。今回、自己からも容易に採取できる脂肪細胞を用いることにより、より臨床への発展が期待できるものとなっている。脂肪細胞由来の間葉系幹細胞を用いることは、今後、他の伝子治療のベクターとして用いることができる可能性を広げるだけでなく、自己由来細胞での治療や再生医療にも応用ができる可能性がある。
