Hyaluronic acid-based hydrogels with independently tunable mechanical and bioactive signaling features.

Extracellular matrix provides critical signaling context to resident cells through mechanical and bioactive properties. To realize the potential of tissue engineering and regenerative medicine, biomaterials should allow for the independent control of these features. This study investigates a hydrogel system based on thiol-modified hyaluronic acid (HA-S) and polyethylene glycol diacrylate (PEGDA).
