Effects of heat and RFGD treatment of Ti6Al4V disks on MG63 cell area following a 1 hr. period of attachment. Disks were prepared, coated with fibronectin, incubated wit MG63 cells, analyzed by SEM as described in Figure 4 and the mean area of cells attached to coated disks was measured. ** > untreated disks (p < 0.01) *** > untreated disks (p < 0.001) based on one-way ANOVA. N (number of cells analyzed) = 52, 69 and 87 for untreated, heat-treated or RFGD-treated disks, respectively. Cells from 3 independent cultures were analyzed for each treatment group.
