Abstract: The elastic modulus of hydrogels is one of the most important factors forcontrolling cell fate. In this study, hydrogels composed ofpoly(N-acryloylglycinamide) (PNAGAm) grafted with arginine (R)–glycine(G)–aspartic acid (D)–serine (S) peptide is designed without a chemicalcrosslinker. The hydrogels are prepared by the conventional radicalcopolymerization of N-acryloylglycinamide with a polymerizable RGDSpeptide. The peptide grafting ratio is easily controlled by adjusting the feedcomposition for polymerization. The hydrogels exhibit thermo-responsivenessof the upper critical solution temperature type based on the PNAGAm moiety.This characteristic re?ects the shape ?x/memory properties of hydrogelsbecause of the reversible formation of multiple hydrogen bonds. The celladhesiveness of the hydrogels drastically improves in the presence of a smallamount of the peptide graft. The hydrogels exhibit good biocompatibility; theadhered cells proliferate on the hydrogels, and macrophages do not showactivation or in?ammation. Surfaces with di?erent elastic modulus regionsare successfully constructed on the same hydrogel by using shape?x/memory properties, allowing the regulation of cell adhesion. This hydrogelsystem o?ers promising opportunities for the design and application offunctional cell sca?olds.
