Hydrogels are remarkably versatile materials for biomedical applications. Their utility is expanded further through the implementation of granular designs based on assemblies of hydrogel microparticles. In this seminar, I will discuss the state-of-the-art in hydrogel biomaterials and describe our progress in developing granular hydrogels for medical and biological applications. First, I will discuss our work developing clickable hydrogel microparticle bioinks for extrusion-based bioprinting and our efforts to elucidate how hydrogel microparticle properties, chemistry, and printing parameters can be tuned to optimize printing outcomes. Subsequently, I will discuss our work on hydrogel microparticle-based scaffolds for mesenchymal stem cell culture, osteoinductive growth factor delivery to regenerate bone defects, and neural progenitor cell delivery to repair the spinal cord after traumatic injury. I will also discuss our work engineering enzyme-functionalized microgel assemblies to regulate oxygen concentration in microbial cultures. Finally, I will share our recent studies on the impact of poly(ethylene glycol) (PEG) immunogenicity on regenerative outcomes with PEG-based granular hydrogels, which show that bone regeneration is significantly affected. This work challenges the view that PEG is a biologically inert “blank slate” and has important implications because of the growing concerns over PEG immunogenicity.
