초록
Interaction between human osteoblast and TiN films was conducted in vitro. TiN films were produced by cathodic arc plasma deposition. The surface was characterized by atomic force microscopy (AFM). TiN films, glass substrates and Ti films were cultured with human osteoblasts for 48 and 72 h hours. Actin stress fiber patterns and microtubules of osteoblasts were found slightly more organized and distributed on TiN films compared to those on the Ti films and the glass substrates. Human osteoblasts also showed slightly higher cell attachment, proliferation, and focal contact adhesion on TiN films compared to those on Ti films and glass substrates. Our results demonstrated that TiN films showed slightly better cellular adhesion of osteoblasts than Ti films and glass substrates in a short-time culture period.
