Experimental Animal Division
Experimental Animal Division Head Atsushi YOSHIKI, Ph.D. Goal The Experimental Animal Division has two missions: (a) to Laboratory, European Mouse Mutant Archive (EMMA) collect, preserve, conduct quality control of and distribute and other centers, and has participated in the International high-quality mouse resources, and (b) to develop novel mouse Mouse Strain Resource (IMSR) to distribute mouse strains models and useful technologies for bioresource activities. Our worldwide. To meet research and social needs, our mice are ultimate goal is to contribute to human welfare by facilitating cleaned up to a specific pathogen-free state, strictly monitored research in life sciences with our mouse resources. The mouse of their health, and accurately tested on their genetic is one of the most superior model organisms used in life modifications and backgrounds. Phenotypic information of sciences to understand human health and overcome diseases. the strains is frequently updated to enrich their value. With Since 2002, RIKEN BRC has been designated as the central these activities, RIKEN BRC plans to build mouse resources core facility for mouse resources in Japan by the National that meet the highest global standards by 2010. The Material BioResource Project (NBRP) of MEXT. With support from Transfer Agreement (MTA) is used to protect the intellectual the scientific community, RIKEN BRC has collected over property rights of the developer of the strains. Training 3,200 mouse strains including genetically modified models, courses concerning advanced technologies are provided for ENU mutants, and inbred and wild-derived strains. RIKEN users to best use our resources. RIKEN BRC collaborates BRC is a founding member of the Federation of International with Asian and other overseas institutes to contribute to the Mouse Resources (FIMRe) together with The Jackson advancement of life sciences in the world. Programs I. Bioresource program: Collection, preservation, qualitycontrol and distribution of the mouse resources II. Development program: Development of novel mouse models and technologies necessary for program I.

We are a founding member of the Asian Mouse Mutagenesis and Resource Association (AMMRA). RIKEN BRC publicly called for applicants in the fiscal years On November 26, 2007, the Bio-Evaluation Center of Korea 2007 and 2008 for research and development programs Research Institute of Bioscience and Biotechnology and to generate novel genetically modified mouse strains RlKEN BRC entered into a Memorandum of Understanding to of immediate demand by the research community. The promote cooperation in areas of mutual interest in laboratory applicants were asked to propose a design of gene constructs animal sciences. We started mutual visits with the Laboratory for genetic modifications, and to produce and submit the Animal Center, Institute of Cytology and Genetics, Siberia recombinant gene constructs to BRC. BRC separately orders Branch of Russian Academy of Sciences in 2008. the third parties to make mouse strains after an open bid. The specialist committee members including those of the BRC Experimental Animal Steering Committee have selected 12 academic organizations to generate 103 gene constructs for genetic modifications in 2007, and 11 organizations for 291 genes in 2008. (ii) Development of genetically uniform mouse strains Transgenic and knockout mouse strains with high-demand such as GFP and human disease models were backcrossed with standard inbred strains to produce genetically uniform congenic strains. (iii) Development of Cre-Zoo Conditional knockout mouse resources have been generated worldwide for the functional analysis of genes. Tissuespecific Cre-transgenic mouse strains are essential tools for dissecting spatiotemporal gene functions together with conditional knockout mice. In cooperation with the Gene Engineering Division, we developed several lines of Cretransgenic mouse strains driven by tissue-specific promoters. Figure 2.

The database includes external measures, blood pressures, blood cell counts, and blood biochemistry measures of 140 mouse strains. The data could be displayed as bar graphs, two-dimensional plots and lists. We also collected images of the coat colors, histopathological sections and X-ray images of the skeleton of 104 various inbred and mutant mouse strains.
