Effect of titanium surface topography on macrophage activation and secretion of proinflammatory cytokines and chemokines.
The macrophage has a major role in normal wound healing and the reparative process around implants. Murine macrophage-like cells RAW 264.7 were used to investigate the effect of titanium surfaces on macrophage activation and secretion of proinflammatory cytokines [interleukin (IL)-1 beta, IL-6, and tumor necrosis factor (TNF)-alpha] and chemokines (monocyte chemoattractant protein-1 and macroph...
متن کاملRole of Titanium Surface Topography and Surface Wettability on Focal Adhesion Kinase Mediated Signaling in Fibroblasts
Changes of titanium surface roughness and surface free energy may influence protein absorption that increases cell differentiation through activation of focal adhesion kinase related pathways. However, the influence of titanium surface roughness and hydrophilicity on fibroblast behavior is not well understood. The aim of this study was to investigate the influence of topography and hydrophilici...
متن کاملTemperature-dependent wettability on a titanium dioxide surface
Controlling surface wettability, expressed in terms of contact angle, is a significant issue in nanotechnology. In this paper, through extensive molecular dynamics simulations, we show that the contact angle of water droplet on a TiO2 surface is considerably influenced by the temperature variations, i.e. as the temperature increases, the contact angle decreases and the surface becomes more hydr...
متن کاملEffect of Hydrofluoric Acid Etching Time on Titanium Topography, Chemistry, Wettability, and Cell Adhesion
Titanium implant surface etching has proven an effective method to enhance cell attachment. Despite the frequent use of hydrofluoric (HF) acid, many questions remain unresolved, including the optimal etching time and its effect on surface and biological properties. The objective of this study was to investigate the effect of HF acid etching time on Ti topography, surface chemistry, wettability,...
متن کاملInfluence of surface topography and surface physicochemistry on wettability of zirconia (tetragonal zirconia polycrystal).
Surface modification technologies are available for tetragonal zirconia polycrystal (TZP) to enhance its bioactivity and osseointegration capability. The surface wettability of an implant material is one of the important factors in the process of osseointegration, possibly regulating protein adsorption, and subsequent cell behavior. The aim of this study was to clarify the effect of topographic...
