| Outline of Final Research Achievements |
Recently, gene knockout or knock-in technologies that disrupts genome sequence, the transcription activator-like effector nuclease (TALEN) system or the clustered regularly interspaced short palindromic repeat (CRISPR)/CRISPR-associated protein (Cas) system, have been developed and used to edit the genomes of various organisms. Our results demonstrate that CRISPR/Cas system more effectively elicits single-step biallelic mutations in mice. In addition, we hypothesized that targeted organs in deficient mice can be produced using a blastocyst complementation in a xenogenic environment. We therefore demonstrate that injection of mouse iPS cells into blastocysts derived from a mutant mouse strain in which the gene necessary to form a particular organ is deficient resulted in generation in vivo of organ almost entirely derived from injected mouse iPS cells.
