Outline of Final Research Achievements |
Pluripotent stem cells (Muse cells) isolated from bone marrow stromal cells were transplanted into three animal models of brain diseases via multiple routes, and their therapeutic effects were examined from various angles. (1) Cerebral infarction model: Muse cells were transplanted transvenously or intranasally, and the recovery of motor function was significantly enhanced. (2) Cerebral contusion model: Muse cells were transplanted intravenously, and the recovery of motor function was significantly enhanced. (3) Alzheimer's disease model: Transplantation of Muse cells intranasally significantly suppressed the deterioration of cognitive function. Based on these findings, we plan to expand the study to experiments using EVs derived from Muse cells.

Academic Significance and Societal Importance of the Research Achievements |
本研究によって人生100年時代、健康寿命延伸時代においても患者QOLに大きく影響を及ぼす脳梗塞、脳挫傷、アルツハイマー病に対して、従来の薬物療法、リハビリテーションなどの治療よりも治療効果の高い細胞療法の開発に目処がついた。しかも本研究では、細胞の静注のみならず経鼻移植という非侵襲的な移植ルートの効果を示した点で、患者負担の軽い再生療法として画期的な成果が得られた。今後はMuse cellから分離できるEVsの研究を展開するとともに、細胞そのものを用いた臨床研究に発展させる予定である。
