| Outline of Final Research Achievements |
When exogenous peripheral blood mononuclear cells preconditioned by oxygen glucose-deprivation (OGD) were administered to rats with post-ischemic sequelae, angiogenesis and neuronal axonal outgrowth were confirmed, and motor-sensory functions were significantly improved 21 days after cell administration (28 days after ischemia).
We developed a bag that can perform OGD stimulation in a closed system for clinical application, and verified the effect of OGD stimulation on human-derived cells. We also confirmed that the number of SSEA3-positive mononuclear cells, a pluripotent stem cell marker, increased after stimulation. We also showed that cells stimulated with this bag also showed therapeutic effects, and we have applied for a patent.

| Academic Significance and Societal Importance of the Research Achievements |
本研究により，脳梗塞後の血管新生，組織修復の機序が明らかとなり，慢性期の脳梗塞治療への応用が検討できる．
末梢血を用いることから，細胞確保が容易で，一般病院にも普及する技術になる．さらに発展させることで，脳梗塞患者の機能回復と予後改善が期待され国民医療費の軽減にもつながる．
