Biological activity of radiation-induced collagen–polyvinylpyrrolidone–PEG hydrogels

The synthesis of novel degradable hydrogels, with designable structures and good biocompatibility, produces attractive materials for use in connective tissue regeneration applications. However, the way in which human fibroblast cells respond to terpolymer hydrogels such as collagen–polyvinylpyrrolidone–polyethylene glycol (C–PVP–PEG) remains largely unknown. The aim of this study was to synthesize a gamma-radiation-induced C–PVP–PEG hydrogel and...
