    Abstract: This invention is to develop a production method for a cell culture carrier comprising a hydrogel having high shape retainability, and cell culture carrier production device, and to provide a structure composed of a cell culture carrier produced using the same.
    The production method comprises a retention step of retaining on a support material a first solution containing a multiple branching polymer comprising polyethylene glycol as the backbone, and having at least one functional group which is one of a nucleophilic functional group and an electrophilic functional group at a side chain(s) and/or a terminal(s), and a gel formation step of forming one or more dot-shaped hydrogels in which a second solution containing a multiple branching polymer comprising polyethylene glycol as the backbone, and having at least one functional group which is the other one of a nucleophilic functional group and an electrophilic functional group at a side chain and/or a terminal, is discharged by a droplet discharge device to land in contact with the first solution retained on the support material.

    Abstract: An object of the present invention is to provide a layered body of cells that is used in a co-culture technique and that is capable of recognizing as paracrine effect of each cell and detecting the effect with high intensity. The layered body of the present invention is a layered body 1A having a layered structure in which a gel layer 20a containing a hydrogel is disposed between at least two cell layers 10a and 10b containing cells of different types from each other, wherein the hydrogel is a multi-branched polymer hydrogel formed by a reaction of: Liquid A containing a multi-branched polymer A, the polymer containing, as a backbone, a polyethylene glycol containing at least three branches, the branches containing one or more electrophilic functional groups in at least one of a side chain(s) and an end(s); and Liquid B containing a multi-branched polymer B, the polymer containing, as a backbone, a polyethylene glycol containing at least three branches, the branches containing one or more nucleophilic functional groups in at least one of a side chain(s) and an end(s), the concentration of components derived from the multi-branched polymers A and B in the hydrogel is from 0.6 to 8% by weight, and the thickness is from 0.02 mm to 2 mm.
