Outline of Final Research Achievements

We investigated induced neural plasticity following combination of intravenous infusion of mesenchymal stem cells (MSCs) and rehabilitation after stroke in rats. The neural plasticity and plasma BDNF levels increased following MSC infusion. These results support the hypothesis that BDNF levels in plasma and DTI tractography might be appropriate to detect therapeutic efficacy in a rat model of ischemic stroke. Future research should be performed to establish a rehabilitation protocol that maximizes the therapeutic efficacy of combination of MSC therapy and rehabilitation.

Academic Significance and Societal Importance of the Research Achievements

再生医療におけるリハビリの重要性は高く、治療効果を最大限に引き出すリハビリプロトコルの確立は非常に重要である。2019年より、脊髄損傷の後遺症に対する再生医療等製品として自己骨髄間葉系幹細胞(ステミラック注)の期限・条件付き承認を受け、実用化が開始された。今後、ステミラック注を用いた再生医療の対象疾患は、脊髄損傷だけではなく脳梗塞などの疾患にも拡大していくことが推測される。MSC療法の治療効果を最大限に引き出すため、リハビリプロトコルの確立と治療効果を反映するバイオマーカーの開発は、大きな役割を果たすものと推測される。
