Then, the samples were exposed to aqueous solutions of amino acids (glycine, alanine and leucine) which were bound onto the polymer chain. The amount of incorporated amino acid is a decreasing function of its molecular size. The incorporated amino acids supported adhesion and proliferation of rat aortic smooth muscle cells and mouse embryonic 3T3 fibroblasts in cultures on the polymer surface. The maximum effect was observed for the smallest molecule of glycine.
