| Outline of Final Research Achievements |
The aim of this project is to develop an efficient and low-cost method to generate gene-manipulated rats for the analysis of brain functions, so that we can provide the research community of this country with gene-modified rats as useful animal resources. For this purpose, we established an optimum culture condition for rat ES cells, a rapid gene-manipulated method using homologous recombination, and a generation method of chimeras that efficiently differentiate to germ cells. Thus, we succeeded in stable generation of gene-manipulated rats. In addition, in order to produce rat sperm from the rat ES cells using our unique mouse-rat interspecies chimeric method, we generated a spermatogenesis-impaired mouse using the conditional recombination technique, and were able to generate rat spermary tissue in a mouse with high efficiency. Our project successfully developed an efficient technique to generate gene-modified rats.
