Title:
CELL-CONTAINING HYDROGEL BODY AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2019/220843
Kind Code:
A1
Abstract:
Provided are a cell-containing hydrogel body and a method for producing same, wherein the size of an interface for cell-cell interaction can be easily and effectively controlled. The method for producing a cell-containing hydrogel body comprises: forming a first hydrogel droplet in a gas phase on the surface of a substrate, the first hydrogel droplet containing dispersed first cells and a first hydrogel polymer; forming a second hydrogel droplet in a gas phase on the surface, the second hydrogel droplet being connected to the first hydrogel droplet and containing dispersed second cells and a second hydrogel polymer; and forming a cell-containing hydrogel body in a gas phase on the surface by gelling a hydrogel droplet connector including a first droplet portion derived from the first hydrogel droplet and a second droplet portion derived from the second hydrogel droplet.
