Abstract

Extrudable hydrogel compositions for printing 3D objects, such as cell growth scaffolds, are provided. Also provided are methods for making the crosslinked hydrogel compositions and the printed objects and methods for culturing cells using the cell growth scaffolds. The hydrogel precursor solutions are aqueous solutions comprising a biocompatible polymer, functionalized polyethylene glycol as a crosslinker and, optionally, cells and/or bioactive factors.
