Covalent Grafting of the RGD-Peptide onto Polyetheretherketone Surfaces via Schiff Base Formation
Figure 3
Adhesion and growth of primary human osteoblasts on bare and RGD-modified PEEK surfaces. Cells were cultured for 24 h or 7 d. After cultivation, cell coverage was analyzed by fluorescence microscopy. Results from triplicate determinations are expressed as mean ± SD (magnification 100, bar 20 m).
