Photopatterned biomolecule immobilization to guide three-dimensional cell fate in natural protein-based hydrogels

Significance Over the past two decades, natural protein-based hydrogel biomaterials have catapulted cell biology into the third dimension, becoming the modern workhorses of 3D cell and organoid culture. Although these systems mimic many important aspects of native tissue while permitting matrix remodeling and biological integration, spatiotemporal control over cell fate within these materials has not been demonstrated. Here, we introduce a...
