Outline of Final Research Achievements

Our brain is thought not to regenerate after severely damaged. For example, limb paralysis caused by stroke hardly recovers with natural healing. However, recent developments in neurobiology research have revealed that our brain has regenerative potential. In this study, we elucidated the regenerative potency of neurons and developed biomaterials for injured brain regeneration.

Academic Significance and Societal Importance of the Research Achievements

ニューロンが細胞分裂しない事実はよく知られているが、そのメカニズムはほとんど知られていなかった。本研究において、ニューロンの細胞分裂保護機構の一端を明らかにした点を学術的意義として強調する。また、本研究で開発した人工足場材料が脳卒中などの損傷脳再生への応用展開が期待されるという点を社会的意義として強調する。
