Outline of Final Research Achievements

Intravenous administration of human adipose-derived stem cells (hADSC) 24 hours after induction of cerebral hemorrhage improved motor functions and cognitive functions worsened by cerebral hemorrhage using collagenase-induced cerebral hemorrhage model mice (C57BL/6). The neurological improvement after intracranial hemorrhage was achieved by a decrease in CD11b + cells around hematomas in the hADSC group at the subacute stage. Subsequent evaluation by flow cytometry showed that the absolute numbers of macrophages and microglia were suppressed in the brain by administration of hADSC.
These results indicate that hADSC suppresses immune cells during the acute to subacute phase of cerebral hemorrhage and improves neurological findings at the chronic phase.

Academic Significance and Societal Importance of the Research Achievements

本研究の結果は、予後を改善し得る治療に乏しい急性期脳出血において、慢性期の神経学的後遺症を軽減し得る治療が、脂肪組織由来間葉系幹細胞を用いることで達成可能である可能性を示している。
すでに脳梗塞に対する骨髄由来間葉系幹細胞を用いた治験が多数行われているが、本研究の結果は、間葉系幹細胞を用いた細胞治療が、脳出血という新たな疾患をターゲットとし得ること、またより侵襲が少なく入手可能な脂肪組織由来の間葉系幹細胞によっても、脳卒中の予後を改善し得る可能性を示唆している。
