The substratum surface morphology plays vital roles in cellular behavior such as adhesion, spreading, migration, proliferation and differentiation We investigated here the structure of a cellular adhesive protein, fibronectin (Fn) adsorbed on both spin-coated films (flat film) and honeycomb pattern films made of poly-ε-caprolactone by using atomic force microscope and confocal laser scanning microscope in relation to the role of the substratum surface morphology in cellular behavior. Although the adsorption saturated at mono-layer adsorption level on both substrates, the structure was inhomogeneous and depend on the surface morphology of substrates: Fn formed fibril-like aggregates on the flat films. Contrary, they adsorbed around the pores on the honeycomb films.
