Research Areas

We develop technologies to monitor and to analyze dynamic nature of mammalian cells, which will be useful tools for phenotyping biological resources collected at the BioResource Center. In order to achieve this goal, our team uses genetic, genomic and transgenic/gene targeting approaches. Our focus is in the following areas. 1. Visualization and purification of pluripotent embryonic cells and germ cells, and genome wide analysis of gene expression to understand genomic reprogramming processes. 2. Identification and functional characterizations of genes required for mammalian early development through the analysis of t-complex mutant mice. 3. Novel research technique to analyze expression of non-coding RNAs during development. 4. Functional genomic analysis using BAC transgenesis technology 5. Evaluations of functional processes in live animals by in vivo imaging
