Developmental Biology

Overview

The nervous system is essential for making human beings what they are. There are, however, still many mysteries concerning how it is built. We are focused on developmental mechanisms of the nervous system, which will provide insights into regenerative medicine to rebuild it after its damage. We are constantly working on new research projects using the latest techniques in molecular and developmental biology. We have developed the in vivo electroporation method in mouse embryos and identified a unique gene, Nepro, which is necessary for the maintenance of early neural stem cells. We have recently found a novel mechanism for controlling dendrites of neurons.

  1. Molecular mechanisms for the maintenance of early neural stem cells in the neocortex
    　Mammalian early neural stem cells have the potential to give rise to many types of neurons and glia. We have been studying the molecular mechanisms, which are key to utilizing multipotent neural stem cells for application, by characterizing functions of early neural stem cell-specific genes that we have found.

  2. Formation and function of neural circuits
    　We are also interested in how neuronal subtype-specific features are determined, how neural circuits are formed and how the circuits work in vivo at molecular and cellular levels. We have been addressing them, using conditional gain- and loss- of-function approaches in mice.
