Outline of Final Research Achievements

To perform genome editing on fish and crustaceans, the microinjection method (MI) on fertilized eggs is usually used. However, few species of fish and crustaceans have been established as model organisms, and it is difficult to systematically obtain fertilized eggs in non-model organisms. Therefore, we tried to develop a genome editing method without MI for fertilized eggs.
We focused Vitellogenin system. In this system, proteins generated in liver are brought into eggs via blood system. We could bring GFP from liver into yolk-sac in eggs,but failed into cytoplasm of eggs.

Academic Significance and Societal Importance of the Research Achievements

今回の研究でマイクロインジェクション法を用いないゲノム編集法の開発には成功しなかった。しかし、肝臓で作られたタンパク質を卵黄に蓄積することに成功した。
魚類の受精卵の生残率は、卵質、つまり、発生に必須あるいは優位な物質がどれだけ卵に蓄積されているか、により大きく異なる。
今回開発したビテロゲニンシステムを活用することにより、卵質を高め、養殖業に活用することが期待できる。
