Disclosed is a cerebral infarction treatment material that improves cerebral function by recovering vascular injury at a cerebral infarction site. The therapeutic material for cerebral infarction according to the present invention contains dental pulp stem cells containing at least one of CD105 positive cells, SP cells, CD24 positive cells, CD133 positive cells, CD271 positive cells and CD150 positive cells. It is also possible to contain secretory proteins of dental pulp stem cells. The transplanted dental pulp stem cell does not directly differentiate into neural progenitor cells or neurons, but indirectly participates in the promotion of differentiation, eliminates the cerebral infarction site, and cures it to a normal site.脳梗塞部位の血管障害を回復して脳機能を改善させる脳梗塞治療材を提供する。本発明に係る脳梗塞治療材は、CD105陽性細胞、SP細胞、CD24陽性細胞、CD133陽性細胞、CD271陽性細胞及びCD150陽性細胞のうち少なくとも何れか一つを含む歯髄幹細胞を含有する。歯髄幹細胞の分泌蛋白質を含有することも可能である。移植された歯髄幹細胞は、神経前駆細胞又は神経細胞に直接分化せず、間接的に分化促進に関与して、脳梗塞部位を解消させて正常部位に治癒させる。
