Cell structure, non-human model animal, method for producing non-human model animal, and method for evaluating test substance

摘要

An object of the present invention is to provide a non-human model animal having abundant stromal tissue, a cell structure useful for producing the non-human model animal, a method for evaluating a test substance using the non-human model animal, and the non-human It is to provide a method for producing a model animal. According to the present invention, the biocompatible polymer block includes at least cancer cells and mesenchymal cells, and a plurality of the biocompatible polymer blocks are disposed in the gaps between the plurality of cells. A cell structure is provided.
