摘要
An object of the present invention is to provide a biocompatible macromolecular porous body, which enables provision of a cell structure showing a high number of cells and a high number of blood vessels; a method for producing the same; and a biocompatible macromolecular block and a cell structure. According to the present invention, there is provided: a method for producing a biocompatible macromolecular porous body which includes a step (a) of cooling a solution of biocompatible macromolecules to be in an unfrozen state, the difference between a temperature of a portion at the highest liquid temperature within the solution and a temperature of a portion at the lowest liquid temperature within the solution being lower than or equal to 2.5°C and the temperature of the portion at the highest liquid temperature within the solution being lower than or equal to a melting point of a solvent, a step (b) of freezing the solution of biocompatible macromolecules obtained in the step (a), and a step (c) of freeze-drying the frozen biocompatible macromolecules obtained in the step (b); the biocompatible macromolecular porous body; a biocompatible macromolecular block; and a cell structure.
