Outline of Final Research Achievements

Animal transgenesis involves three major technical steps; isolation of fertilized eggs, microinjection and subsequent transfer of eggs into recipient females, which require sophisticated equipment as well as highly skilled personnel to perform the task. Genome-editing via Oviductal Nucleic Acids Delivery (GONAD) method developed in this study is a novel technique enabling genome editing in mice through intraoviductal instillation of genome editing components followed by an in vivo electroporation. Since the GONAD does not require ex vivo manipulation of zygotes, it is possible to produce genome-edited mice even by the researchers who do not possess special skills for ex vivo handling and micromanipulation of embryos.
