    摘要: 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.
