Outline of Research at the Start

申請者らは、細胞外マトリックス成分で細胞表面を被覆し立体的な組織を構築する技術を基に、血管網を備えた表皮/真皮一体型の複合型培養皮膚を構築し、マウス皮膚欠損モデルにおいて良好な皮膚再建に成功した。本研究では、この技術をさらに発展させ、幹細胞あるいはiPS細胞由来の皮膚付属器前駆細胞など複数種類の細胞ソースを組み合わせることによって、機能および整容面において重要な皮膚付属器を有し正常皮膚に類似した培養皮膚の構築を目指す。

Outline of Final Research Achievements

In this research, human vascularized 3D skin was constructed by cell accumulation technique via coating with extracellular matrix components on the cell surface. Cultured human skin produced by co-culturing microvascular endothelial cells and lymphatic endothelial cells has shown good engraftment after transplantation. On the other hand, this culture system may not recapitulate the microenvironment necessary for forming sweat gland structures, and further verification is needed.

Academic Significance and Societal Importance of the Research Achievements

毛細血管やリンパ管の脈管系や汗腺を含有した移植用のヒト培養皮膚を構築することができれば、皮膚の再生医療のみならず、医薬品候補化合物などの安全性や薬物動態など信頼性が高い評価デバイスの実現にもつながることが期待される。
