Abstract: The purpose of the present invention is to provide an adhesion improver that is to be used for an edible base material for cell culturing and contains an edible and non-lethal animal-derived component, a cell culturing scaffold material containing the adhesion improver, a tissue body containing the cell culturing scaffold material, etc. A cell culturing scaffold material suitable for the production of a cultured meat can be produced by applying an adhesion improver containing an edible and non-lethal animal-derived component to an edible base material for cell culturing.

Abstract: The purpose of the present invention is to provide: an adhesion improver which contains an edible plant-derived component and is used in an edible base material for culturing cells; a cell culturing scaffolding material containing said adhesion improver; and a tissue body containing said cell culturing scaffolding material. A cell culturing scaffolding material suitable for producing cultured meat can be produced by applying an adhesion improver containing an edible plant-derived component to an edible base material for culturing cells.

Abstract: The present invention provides a foam body suitable for producing a cultured meat having a good texture. The foam body of the present invention includes alginic acid and/or an alginate. The foam body has an elastic modulus M, as determined by a test, of 8×104 Pa or less. In the test, the foam body is immersed in 22±3° C. water for 4 hours to prepare a specimen having a post-immersion thickness of 5±1 mm. Stress and strain caused in the specimen are measured by applying a load to the specimen for 5 seconds to compress the specimen in a thickness direction at 0.5 mm/sec. A stress caused in the specimen when the specimen is compressed by 10% of an initial thickness is determined, and a value obtained by dividing the stress by a corresponding strain is determined as the elastic modulus M.
