CELL STRUCTURE, NON-HUMAN MODEL ANIMAL, METHOD FOR PRODUCING NON-HUMAN MODEL ANIMAL, AND METHOD FOR EVALUATING TEST SUBSTANCE

摘要

The purpose of the present invention is to provide: a non-human model animal rich in interstitial tissue; a cell structure useful for production of the non-human model animal; a method for evaluating a test substance using the non-human model animal; and a method for producing the non-human model animal. The present invention provides a cell structure comprising biocompatible polymer blocks and at least cancer cells and mesenchymal cells. The multiple biocompatible polymer blocks are disposed in the space between the multiple cells.
