    摘要: Objects of the present invention are to provide a base film for cell culture that enables mass production of homogeneous and high-quality cell aggregates even without the use of a biological serum, and to provide a base film-forming agent for forming the base film, and a substrate for producing cell aggregate. The present inventors provide a base film-forming agent for cell culture including a polymer, a cell adhesive substance, and a solvent, wherein the polymer contains a repeating unit derived from a monomer of formula (I) below:




    wherein Ua1, Ua2, Ra1, and Ra2 are as described in the specification and the claims.

    摘要: A method for manufacturing an extracellular matrix composition includes providing a gel, carrying out a crosslinking treatment, carrying out a single type cell culture, carrying out a decrosslinking treatment, and carrying out an extraction treatment. The crosslinking treatment includes adding a crosslinking agent to the gel to obtain a crosslinked gel. The cell culture includes implanting cells of a singular type on the crosslinked gel and incubating the cells by adding a culture solution. The decrosslinking treatment includes adding a decrosslinking agent to the crosslinked gel to obtain a decrosslinked mixture that contains an extracellular matrix. The extraction treatment includes filtering the decrosslinked mixture to obtain the extracellular matrix composition that is in a liquid state.
