TISSUE-FORMING BASE MATERIAL DERIVED FROM LIVING BODY, METHOD FOR PRODUCING TISSUE DERIVED FROM LIVING BODY USING THE SAME AND TISSUE DERIVED FROM LIVING BODY
PROBLEM TO BE SOLVED: To provide a base material for forming a thick tissue derived from a living body in a relatively short time, a method for producing a tissue derived from a living body and a tissue derived from a living body.SOLUTION: There is provided the tissue forming base material 1 derived from the living body wherein a filmy tissue body 2 is formed on the surface and the tissue 3 derived from the living body is formed by separating the tissue body 2 in an environment where a living body tissue exists. The base material 1 includes: a columnar structure 6 whose outer peripheral surface is a forming surface of the tissue body 2; and an auxiliary structure 7 juxtaposed with a space from an outer surface of the columnar structure 6 in an outer radial direction.【課題】比較的短期間で厚みのある生体由来組織を形成するための基材、これを用いた生体由来組織の生産方法及び生体由来組織を提供する。【解決手段】生体組織材料の存在する環境下におくことにより、その表面に膜状の組織体2を形成し、組織体2を剥離して生体由来組織3を形成するための基材1であって、外周面が組織体2の形成面となる柱状構造体6と、柱状構造体6の外面から半径外方向に間隔をあけて併設された補助構造体7と、を備えることを特徴とする生体由来組織形成用基材1である。【選択図】図1
