Figure 3From: Adherence of human oral keratinocytes and gingival fibroblasts to nano-structured titanium surfaces Adherence of human oral keratinocytes to CpTi control (C) and nano-structured (N1 and N2) surfaces. (a) Adhered cells were stained with Live/Dead BacLight and viewed in a fluorescence microscope. The scale bar represents 50 μm. (b) Graphs showing mean number of adhered cells ± SEM from three independent experiments.Back to article page
