Outline of Final Research Achievements

Intraventricular injection of lipophilic dye enabled the labeling of the ependymal cells/radial glial cells in the Xenopus laevis, and new neurons are considered to be derived from these cells. For establishing the system for the spatiotemporal expression of the exogenous genes in amphibians, we compared the efficacy of gene recombination systems and found that the efficacy of the expression of the exogenous gene in the Flp/FRT system is superior to that in the Cre/loxP system at a genome level, however, that in the latter one is almost similar to that in the former one at a level of the activity of fluorescent dyes.

Academic Significance and Societal Importance of the Research Achievements

本研究は、未だ抜本的治療法が開発されていない脊髄損傷に関し、これまで行われてきた哺乳類を用いた研究に替え、損傷後の自発的再生により神経機能回復まで至る"再生可能動物"である両生類を用いその再生メカニズムを明らかとすることで、将来的なヒトへの応用を目指すための基礎的な知見を与え得るものである。現在は、"再生可能動物"の再生メカニズムの解明とそのヒトへの応用という大目標を果たすための実験ツールの整備や基盤知見の取得を行っている段階であり、困難に直面する場面もあるものの、ひとつひとつ着実に進捗しているものである。
