Outline of Final Research Achievements

Development of a surrogate production through transplanting genome editing tool delivered germ cells into a recipient fish with a short generation time and a smaller body size can accelerate a creation of genetically improved aquaculture strain by genome editing. In this study, we developed an electroporation technique to deliver CRISPR/Cas9 RNP complex (containing Cas9 protein, crRNA and tracrRNA) into donor testicular cells.

Academic Significance and Societal Importance of the Research Achievements

ゲノム編集を用いた遺伝形質の改良であっても、交配による有用遺伝子変異の固定は必須である。本研究で明らかにしたエレクトロポレーション処理による精巣細胞へのゲノム編集ツール導入法は、これら処理細胞を、小型近縁種へと移植する代理親魚技術とあわせることで、代理親体内での短期間かつ小飼育スペースなゲノム編集配偶子生産法の開発へと繋がり、将来、ゲノム編集によって海産魚の有用養殖品種を樹立する際に、役立てられていくものと期待される。
