Title METHOD OF REMOVING CELL
Abstract In the transplant of a living organism tissue, such as a heart valve, taken from an animal, etc. into a human body, a cell removing solution for removing original cells from the living organism tissue is provided with flow approximately equal to the bloodstream of transplant recipient living body, and the living organism tissue is placed in the flow so as to effect immersion of the living organism tissue in the cell removing solution. In the immersion, it is preferred that the living organism tissue placed in the cell removing solution, while being rotated, be irradiated with microwave. As a result, original cells can be removed from the living organism tissue uniformly and reliably, so that the biocompatibility of living organism tissue after transplant can be enhanced.
Scope of claims (In Japanese)
【請求項1】所定の生体組織を移植する際に、当該生体組織を所定の細胞除去溶液に浸漬し、前記生体組織の原細胞を除去する脱細胞化方法であって、前記細胞除去溶液に対し、所定の拍動流を付与し、当該拍動流中に前記生体組織を置くことを特徴とする脱細胞化方法。

【請求項2】所定の生体組織を移植する際に、当該生体組織を細胞除去溶液に浸漬し、前記生体組織の原細胞を除去する脱細胞化方法であって、前記細胞除去溶液中の生体組織にマイクロ波を照射することを特徴とする脱細胞化方法。

【請求項3】前記細胞除去溶液に対し、所定の拍動流を付与し、当該拍動流中に前記生体組織を置くことを特徴とするクレーム2記載の脱細胞化方法。

【請求項4】前記マイクロ波の照射部位と前記生体組織とを相対回転しながら前記マイクロ波を照射することを特徴とするクレーム2又は3記載の脱細胞化方法。
