Method for producing regenerative organ primordium provided with guide for transplantation, composition containing regenerative organ primordium provided with guide for transplantation produced thereby, and method for transplanting regenerative organ
The purpose of the present invention is to provide a method for producing a regenerative organ primordium for transplantation, said regenerative organ primordium for transplantation ensuring continuity with a recipient after transplantation and facilitating transplantation procedures. Provided is a method for producing a regenerative organ primordium provided with a guide for transplantation, said method comprising: a step for preparing a regenerative organ primordium by tightly contacting a first cell mass, which substantially consists of mesenchymal cells, with a second cell mass, which substantially consists of epithelial cells, and culturing these cell masses within a supporting medium； and a step for inserting the guide into the regenerative organ primordium.
