Title:
METHOD TO SUPPRESS DEDIFFERENTIATION OF CELLS THAT READILY DEDIFFERENTIATE, METHOD FOR PREPARING SAID CELLS, AND METHOD FOR PRODUCING SUBSTANCE
Document Type and Number:
WIPO Patent Application WO/2018/021362
Kind Code:
A1
Abstract:
The present invention relates to a method to suppress the dedifferentiation of cells that readily dedifferentiate, said method including: (1) a step in which the cells are applied to a polymer porous film; and (2) a step in which the cells are cultivated and allowed to multiply, wherein the polymer porous film is a polymer porous film with a three-layer structure, having a surface layer A and a surface layer B that have a plurality of holes, and a macrovoid layer that is sandwiched between the surface layer A and the surface layer B, the average hole diameter of the holes present in the surface layer A is smaller than the average hole diameter of the holes present in the surface layer B, the macrovoid layer has dividing walls that are connected to the surface layers A and B, and a plurality of macrovoids that are surrounded by the dividing walls and the surface layers A and B, and the holes in the surface layers A and B are in communication with the macrovoids.
