(A) MCP-1 release from MIN6 cells encapsulated in 10% PEG hydrogels incubated with or without a cytokine cocktail (1× cytokine: 750 units/mL IFN-γ, 10 units/mL IL-1β, and 500 units/mL TNFα). (B) MCP-1 release from MIN6 cells encapsulated in PEG hydrogels or PEG-peptide hydrogels incubated in 1× cytokine cocktail (peptide = 100μM, mean ± SEM, n=4). Asterisks represent statistical significance between indicated groups (p<0.05).
