Polyethylene glycol (PEG) hydrogels are tunable cell culture platforms that recapitulate tissue geometry, water content, and bulk modulus. Despite these benefits, PEG hydrogels elicit an acute immune response, limiting their use in regenerative medicine, and they critically underrepresent the cell-instructive proteins found in the extracellular matrix (ECM). Here, I developed a new class of tissue-specific PEG-based materials and provided biocompatible strategies to improve the user handling and cell viability post-encapsulation when using these hydrogels. I also demonstrated that decreasing the protein fouling to PEG does not decrease the foreign body response to implanted hydrogels, a common misconception in the field. …
