Cell adhesion to cathodic arc plasma deposited CrAlSiN thin films

► We examined osteoblast cell response to CrN, CrAlSiN and Ti thin films in vitro. ► Cell adhesion, actin stress fibers and microtubule organization depended on the film composition. ► Results showed good focal contact adhesion and cell proliferation on the CrAlSiN and Ti thin films but not on the CrN thin films.
