筆者らは,神経幹細胞移植による脊髄損傷の再生医療の開発を長年行っており,ついにヒトiPS細胞由来神経前駆細胞を用いた亜急性期脊髄損傷の再生医療Phase I-IIa試験(臨床研究)の “First-human-trial” を開始した。また,幹細胞移植による治療メカニズムの研究も世界中で行われており,本論ではこれまでに明らかになってきた治療メカニズムと,iPS細胞による最新の知見について概説する。
Abstract
We have performed extensive basic and preclinical research to investigate the role of human induced pluripotent cell-derived neural stem/progenitor cell (hiPSC-NS/PC) grafts in spinal cord injury (SCI) models, and evidence obtained from animal experiments confirms the safety and effectiveness of this approach. We have initiated a first-in-human clinical trial of hiPSC-NS/PC transplantation in patients with subacute SCI. Research on the therapeutic mechanism underlying stem cell transplantation therapy is ongoing worldwide; this paper outlines the current knowledge of the therapeutic mechanism.
