Figure 6From: Primary human nasal epithelial cell response to titanium surface with a nanonetwork structure in nasal implant applications Cell adhesion images, using immunofluorescent staining, after 12 h of cell incubation. Cell adhesion images, using immunofluorescent staining, of HNEpC on the Ti specimens (M, E1, and E2) after 12 h of cell incubation: dual staining of DAPI for nuclei (blue color) and rhodamine phalloidin for actin filaments (red color) (arrow: spreading cells).Back to article page
