| Laboratory animals are broadly utilized as genetic resources in medical and life science researches. Their characteristics are genetically proved and are extensively controlled in their microbiological quality. In Laboratory Animal Research Core, we are committed to analyzing mutant/ genetically-modified mouse, studying microbial infection of laboratory animals, creating disease-model mice by genetic modification, and establishment of embryonic stem cells and consomic mouse strains. We also engage in health control of laboratory animals as well as in education and technical guidance of laboratory animal science and animal experimentation. |
| ● Research on infection of mice and rats |
1) Development of high throughput diagnostics method for infectious diseases in mice and rats

3) Virulence mechanism and diagnostics of Helicobacter infection in mice
|
| ● Genetic analysis of mouse |
1) Searching hypertension・obesity・diabetes - related genes
2) Searching genes responsible for mutant mice
|
| ● Development of biological resources |
