Patterning of HPG-PEG hydrogels. Schematic representation of (a) ASC encapsulation within HPGMA / PEGDA composite hydrogels prior to functionalization with FITC-RGDSC and (b) TAMRA-RGDSC patterning by UV catalyzed reaction. (c) Representation of thiol-radical initiated “click” reactions for photopatterning “yne”-containing HPGMA polymers with cysteine containing RGDSC peptides. This scheme shows all possible reactions that may occur during the patterning process.
