Outline of Final Research Achievements

I used neonatal mouse brain injury model, and found that radial glial fibers persist after neonatal brain injury to support the migration of ventricular-subventricular zone derived neuroblasts toward the injured area. new neurons and radial glial fibers form N-cadherin-dependent homophilic adhesion to promote fiber-guided neuronal migration. Furthermore, N-cadherin-containing sponge promotes neuronal migration and maturation, and functional recovery after neonatal brain injury.

Academic Significance and Societal Importance of the Research Achievements

放射状グリアの生後の機能はこれまで不明であったが、本研究により新生児期におけるその新しい役割を見出すことができたことは学術的意義が大きい。
また、新生児脳が高いニューロン再生能を持つ詳細な制御メカニズムを世界で初めて発見し、その方法を応用することによって再生の促進に成功した。このことから、新生児脳傷害におけるニューロン再生の臨床応用へつながる大きな前進となった意味で社会的意義が高い。
