Modifications of poly(2-hydroxyethyl methacrylate) (PHEMA) with laminin-derived Ac-CGGASIKVAVS-OH peptide sequences have been developed to construct scaffolds that promote cell adhesion and neural differentiation. The Ac-CGGASIKVAVS-OH peptide was immobilized to the sulfhydryl groups by 2,2'-dithiodipyridine linking reagent via 2-[4-(2-pyridyldisulfanyl)butanamido]ethyl methacrylate. Superporous Ac-CGGASIKVAVS-OH-modified PHEMA scaffolds significantly increased the number of attached mesenchymal stem cells and their growth area on the hydrogel surface in the absence and in the presence of serum in the culture medium. Additionally, the Ac-CGGASIKVAVS-OH peptide supported the attachment, proliferation, differentiation and process spreading of human fetal neural stem cells during the first two weeks of expansion and contributed to the formation of a high percentage of more mature neural cells after four weeks of expansion.
