title: Surfaces modified with covalently-immobilized adhesive peptides affect fibroblast population motility.
abstract: Cell population motility and adhesion of rat skin fibroblasts were evaluated on aminophase glass modified with covalently-immobilized biologically active peptides, specifically, either arginine glycine-aspartic acid-serine (RGDS) or tyrosine-isoleucine-glycine-serine-arginine-glycine (YIGSRG). Fibroblast population motility was decreased and adhesion was increased on substrates modified with covalently immobilized RGDS peptide compared to substrates with the covalently immobilized non-adhesive peptides arginine-glycine-glutamic acid-serine and arginine-aspartic acid-glycine-serine. Fibroblast motility was not significantly changed on substrates modified with covalently-immobilized YIGSRG peptide; however, fibroblast adhesion was decreased on that substrate.
