Rats are widely used in life science and biomedical research as experimental animals with characteristics that differ from those of mice. The NBRP-Rat project supports a broad range of research by collecting, preserving, and distributing valuable rat resources to researchers in Japan and around the world.
We develop and maintain an internationally accessible database of strain and phenotype information. We also promote the development and dissemination of new reproductive technologies for rats.
I have the honor of serving as the Project Leader of the NBRP-Rat project, beginning with the final year of its fifth phase. I am committed to increasing awareness of the unique value and advantages of rats as research models and to further enhancing NBRP-Rat as an accessible and valuable research resource, thereby contributing to continued advances in life sciences. We encourage researchers to take advantage of the resources and services provided by NBRP-Rat.

This project is one part of the National BioResource Projects (NBRP) in Japan for more than 20 species including animals, plants, microbes, tissues and DNAs. It is founded by the Japanese Ministry of Education, Culture, Sports, Science and Technology (Monkasho) and started in 2002.
The Institute of Laboratory Animals, Graduate School of Medicine, Kyoto University, is the central facility for the species rat. The 5th term of NBRP-Rat started in 2022, following the 1st, 2nd, 3rd and 4th term (2002-2021).
The major goals of NBRP-Rat are the collection, preservation and supply of rat strains. The repository includes strains from Japan and abroad, spontaneous mutants, congenic and recombinant strains as well as transgenic and mutagenized rats. Deposited rat strains are not only conserved as cryopreserved embryos and sperm. Many reference and frequently used rat strains are also maintained as living animals under SPF conditions. About all strains, quality assurance through microbial and genetic monitoring are conducted.
Furthermore, NBRP-Rat provides a unique database on various rat strain phenotypes accompanied with basic genetic information. This allows scientists the selection of standardized and research specific strains. From the 2nd term of NBRP-Rat, the Rat Resource and Research Meeting was initiated as exchange meeting for information around the rat.
This project promotes further utilization of the rat as a research tool in many fields of science.
