Decreasing the width of the nano rough region on patterned Ti substrates decreased osteoblast adhesion after four hours.
Notes: Data are mean ± SEM; n = 3; *p < 0.05 and **p < 0.01 compared with the 80:45 μm grid pattern. Indicated on this graph are the percent of cells adhering specifically to the nano rough region of each substrate. This data was collected from the same experiments as those completed in Figures 5 and 6.
