Commercial media and surfaces for cell cultivation do not promote conditions for cell cultivation and proliferation with specific interactions cell-material surface. The aim of this thesis is developing surfaces for cell cultivation which mimic conditions in living tissues. The approach introduced in this thesis is based on applying biomimetic peptide ligands on inert supporting materials with non-fouling properties. Considering that a choice of a ligand sequence and distance between peptides can dramatically influence the outcome, a few model peptides with varying parameters were synthesized and investigated. The cell adhesive peptides were synthesized by solid phase peptide synthesis and scrambled peptides were synthesized and tested as well. Spatial deposition of peptides is another highly important point of study. The 'click'- reaction was used to successfully immobilize the peptides on produced surfaces. The distance between the peptide molecules on the surfaces was controlled by their concentration in a reaction mixture. The reference samples were immobilized with radiolabeled peptides for quantitative estimation of the peptides present. Then, the materials with different types of peptides and range of concentrations were examined via cultivation of cell cultures. The experiments were focused on...
