Successful production of genome-edited rats by the rGONAD method.

ABSTRACT: BACKGROUND:Recent progress in development of the CRISPR/Cas9 system has been shown to be an efficient gene-editing technology in various organisms. We recently developed a novel method called Genome-editing via Oviductal Nucleic Acids Delivery (GONAD) in mice; a novel in vivo genome editing system that does not require ex vivo handling of embryos, and this technology is newly developed and renamed as "improved GONAD" (i-GONAD). However, this technology has been limited only to mice. Therefore in this study, we challenge to apply this technology to rats. RESULTS:Here, we determine the most suitable condition for in vivo gene delivery towards rat preimplantation embryos using tetramethylrhodamine-labelled dextran, termed as Rat improved GONAD (rGONAD). Then, to investigate whether this metho
