Research Abstract

実際の臨床応用にあたっては、一般的に尿路上皮は管空組織内にあることから、内視鏡等を用いて採取しやすく、再生能力も高い。一方、平滑筋細胞は組織の深部にあり採取しづらい。そこで、尿路上皮細胞層を作成後に、第二段階として上皮細胞から間葉系細胞が誘導される現象(Epithelial Mesanchimal Transformation/EMT)の原理を応用することで、平滑筋細胞層を作成することを検討中である。このように、多段階的に臓器を作成することで、より確実で効率的な実際応用可能なプロセスを構築することが可能である
EMT の原理および機械的刺激を応用することで、細胞および組織の誘導過程をより機能的および効率化できる可能性がある。伸展刺激および電気刺激を負荷し、誘導される平滑筋細胞に一定の空間的配置と電気的共同性をもたせる
