Bioinspired tuning of glycol chitosan for 3D cell culture

We developed glycol chitosan-based thermo-reversible hydrogels that can provide a facile, convenient and reproducible method for the formation of 3D cell spheroids. The spontaneous formation of spheroids on HGC-coated plates was completed within 1 day. Furthermore, this system can be useful for co-culturing heterotypic cells to form spheroids that mimic biological systems.
