Cell attachment on applied surfaces. The density of attached cells to TCPS (
    n
 = 14), unanodized titanium (n = 3) and anodized titanium with nanostructures (n = 18). Evaluation of cell adhesion was conducted by counting stained nuclei of attached cell per square centimeter of the substrate surface. Asterisk denotes P < 0.05. Data are mean ± SEM.
