| Outline of Final Research Achievements |
Using human-derived injury/ischemia-induced stem/progenitor cells (h-iSC), which were isolated from ischemic brain tissues of stroke patients requiring decompressive craniectomy and partial lobectomy for diffuse cerebral infarction, we transplanted h-iSC into post-stroke mouse brains to investigate the efficiency by these cells. We found that some h-iSCs survived around the injected sites and that they expressed a neuronal marker Tuj1 and MAP2. In addition, mice received h-iSC improved neurological functions compared with controls. These results indicate that h-iSC can become a novel cell-based therapy for patients with stroke in the future.

| Academic Significance and Societal Importance of the Research Achievements |
本研究の結果、h-iSCによる細胞移植療法は、これまで有効な治療法が限られていた脳梗塞患者に対する新規治療法になり得ることが示唆された。また、本治療法の確立及び発展は、将来、脳梗塞患者をはじめとし、様々な神経疾患に対して多大なる貢献をもたらし得ることから、本研究成果は意義あるものであると考えられた。
