TISSUE EQUIVALANT FOR TRANSPLANTATION AND PROCESS FOR PRODUCING THE SAME

摘要

A tissue equivalent for transplantation having a three-dimensional structure which is cultured in vitro, contains cells to be transplanted and which can be transplanted into a living body after the culture, characterized by including a scaffold layer mainly culturing a scaffold constituting the three-dimensional structure and a cell layer which is localized at least in a part of the surface of the tissue equivalent for transplantation continuously with the scaffold layer and which contains the cells to be transplanted or extra cellular matrix in a larger amount than the scaffold layer. This tissue equivalent is appropriately employed as a tissue equivalent for transplantation in a relatively large size. This tissue equivalent enables realization of prompt fixation to the neighborhood of the transplanted tissue and prevention of falling off. <IMAGE>
