Research Summary

Ryoichiro Kageyama (M.D., Ph.D.)

We are analyzing the regulatory mechanism of proliferation and differentiation of neural stem cells (NSCs). Embryonic NSCs proliferate intensively and give rise to various types of neurons and glial cells, thereby forming complex brain structures, whereas adult NSCs lose such proliferation and differentiation competencies and therefore cannot regenerate diseased or damaged brain tissues. We aim to elucidate the genetic-level differences between embryonic and adult NSCs and establish the technical basis for brain tissue regeneration.
