    Preparation of soft poly(amino acid) hydrogels containing biomimetic cell-adhesive peptides was investigated. Covalently crosslinked gels were formed by radical co-polymerization of methacryloylated macromonomer poly[N5-(2-hydroxyethyl)-L-glutamine-stat-L-alanine-stat-methacryloyllysine] with 2-hydroxyethyl methacrylate (HEMA) as minor co-monomer. Hydrogels carrying biomimetic peptides were prepared by using methacryloylated peptides, such as methacryloyl-GGGRGDSG-OH and methacryloyl-GGGYIGSR-OH, as additional monomers in the polymerization mixture. While unmodified hydrogels showed very low cell adhesion, due to their highly hydrophilic nature, the incorporation of adhesive peptides significantly improved the adhesion and viability of seeded cells.
