Theoretical Cell Science

We were established as the first informatics laboratory at CiRA, engaging in i) spatio-temporal analysis of cell differentiations to construct fundamental theories, ii) design of 3D tissues derived from iPS cells by single-cell analysis, and iii) development of supporting systems for cell therapy based on artificial intelligence. To enhance quality control of artificially generated cells, we are further developing a reference database of all human cell types at single-cell levels. We are using this database to construct a “cell periodic table” with which we will theoretically find unknown cell types or elucidate the natural history of cell type generation.

Research and Education

Our laboratory directs Japanese Society for Bioinformatics (JSBi) as a board member and leads “SIG on Biological Systems Theory” of JSBi, thus students are encouraged to give a few presentations in a year. Our laboratory has a new system; the wet group conducts demonstration experiments to verify theories, which is uncommon for informatics laboratories. Therefore, students may take a part in either wet or dry group and perform researches. The wet group develops advanced single-cell analysis technologies, measuring omics data from whole human cell types. With the obtained data, the dry group constructs a human cell database (SHOGoiN), developing algorithms and tools to analyze it. Both groups collaborate to challenge the birth mechanisms of cell types or diseased cells.
As educational activities, we have a meeting for journal news and research seminar once a week to polish up speed-reading and presentation skills. From this fiscal year, we started a student exchange program with Berlin-Brandenburg Center for Regenerative Therapies, and enthusiastic students may be allowed to stay in a couple of months even if they are in the first year. Importantly, we have options to hire students in our laboratory to support his or her school expenses.
