Abstract

To provide a scaffolding material for cell culture that has excellent transparency and can be used in scaffold-type cell culture, particularly a scaffolding material for cell culture that can form a scaffolding material with a hydrogel pattern using a simple method by exposure and development.SOLUTION: Provided is a scaffolding material for cell culture containing a fibrous cellulose with an average fiber width of 100 nm or less, and a negative radiation-sensitive component containing a polymerizable compound and a polymerization initiator, the content of the negative radiation-sensitive component being 20 to 200 pts.mass based on 100 pts.mass of the fibrous cellulose, the negative radiation-sensitive component being a component that is soluble in at least one selected from water, alcohol, and a mixed solvent thereof.SELECTED DRAWING: None
