Outline of Final Research Achievements |
The enhanced neural plasticity at the injured tissue and/or in the higher level of spinal cord and brain following intravenous infusion of MSCs in spinal cord injury (SCI) model was thought to be due to protection from neuronal, axonal loss or degeneration in the injured tissue, and stabilization of the blood-spinal cord barrier. Furthermore, we analyzed the variable genes expressed in the motor cortex at the 3 days post-MSC infusion, when functional improvement was observed, and found that there were changes in the expression levels of several genes, which may enhance neural plasticity. Consequently, we found that intravenous infusion of MSCs in SCI may promote the functional improvement through the enhanced neural plasticity induced at the injured tissue and at the upper spinal cord and brain.

Academic Significance and Societal Importance of the Research Achievements |
脊髄損傷後の回復過程において、損傷部位のみならず損傷を受けていない上位に位置する脊髄および脳において、神経の構造および機能の再構築が惹起され、新しい神経回路が構築されることで、神経機能が回復することが知られている。一方、我々は骨髄間葉系幹細胞治療(MSC治療)が神経の再構築を亢進することで良好な機能改善効果を発揮することを明らかにしている。脊髄損傷に対するMSC治療が、損傷脊髄局所ならびに上位脊髄および脳において作用し、神経機能再構築の亢進作用を発揮することで神経機能改善に寄与している可能性があり、そのメカニズムを解明することは次世代の治療法の開発につながる。
