Outline of Final Research Achievements

While functional recovery from transvenous administration of bone marrow mesenchymal stem cells (MSCs) to spinal cord injury (SCI) models has been reported, the role of the brain in spinal cord injury has attracted attention. In this study, MSCs were intravenously administered to acute-phase SCI rats, and 15 genes related to recovery of motor function were extracted from comprehensive gene expression analysis by brain microarray. This suggests that intravenous administration of MSC has neuroprotective and regenerating effects on the brain and is involved in recovery of motor function.

Academic Significance and Societal Importance of the Research Achievements

脊髄損傷患者に対する骨髄間葉系幹細胞の静脈内投与による再生医療の治療メカニズムの一つとして、脳における神経保護作用や神経再生作用が運動機能回復に関与していることがわかり、静脈内投与による脊髄局所だけでなく全身投与によって脳への作用が重要であることが分かった。今後脊髄損傷の再生医療のアプローチとして損傷局所だけでなく、中枢神経全体への治療介入の重要性が示唆された。
