| Outline of Final Research Achievements |
Recently, genome editing in mouse zygotes has become convenient and scalable, in association with various technological developments and improvements such as novel nuclease tools, alternative delivery methods, and contemporary reproductive engineering techniques. We have so far demonstrated the applicability of ultra-superovulation, in vitro fertilization (IVF), and vitrification/warming of zygotes in microinjection-mediated mouse genome editing. Here, we present an example of an application coupling the following three technologies: 1) CRISPR-Cas9 system as the most convenient genome-editing technology, 2) lipofection as the most simple, economical and effortless delivery method, and 3) cryopreserved oocytes created by IVF via ultra-superovulation as the most animal welfare- and user-friendly strategy. We successfully created gene knockout mice carrying insertion/deletion mutations.
