Scaffold-Free Three-Dimensional Cell Culture Utilizing Micromolded Nonadhesive Hydrogels
Research Overview
Self-assembled 3D spheroid microtissues are powerful in vitro models for stem cell research, tissue engineering, and cancer biology, but scale, expense, geometry, and practicality have limited their adoption.
This study presented an easy-to-use, inexpensive, scalable technology for producing complex-shaped 3D microtissues by seeding cells onto micro-molded nonadhesive agarose gels. Various primary cells and immortal cell lines demonstrated that the technique applies across many cell types, while also highlighting how self-assembly behavior differs between them.
