Summary of Activity

By using pluripotent stem cells which can give rise to almost any cell type with special function, it is possible to cure previously untreatable injuries and diseases. For instance, differentiating stem cells into specialized cells with special function and implanting them when the damaged cells cannot heal itself, or even creating a complete organ in the lab and transplanting them to replace a damaged organ. We are promoting researches about stem cells which hold promise for treating previously incurable diseases.

Research Subject

  • • Development and Regeneration of Kidney
    To study the mechanisms that support the developmental competence of kidney germ tissues by using embryonic cells and tissues of experimental animals.

  • • Creating Cancer Stem Cells by Reprogramming Technology
    To study the mechanism of carcinogenesis and develop therapeutic methods by reprogramming cancer cells into cancer stem cells.

  • • Establishment of Disease Model with Patient Specific iPS Cells
    To elucidate the pathogenesis of Ehlers-Danlos syndrome, a kind of heterogeneous connective tissue disorder.

  • • Functional Analysis of Epigenetic Factors in Pluripotent Stem Cells
    We are studying why various cells maintain their different state of differentiation, even though they have the same genetic information.

Outlook for Research

The promising field of Regenerative Medicine is to restore structure and function of damaged tissues and organs. It is also possible to find a way to cure aging and genetic diseases.
