Cell migration influenced by Mg and Mg–6Ag under normoxia. Microscopic images of Saos-eGFP (green) and RF Fibroblasts (red) in coculture or monocultures with the initial wound (0 h) and after 48 h. The white dotted lines symbolize the cell fronts. Scale bar is 100 μm. The cell-free areas after 24 h and 48 h were quantified in relation to the initial cell-free area. Relative cell-free areas are shown as the mean ± SD from two experiments with two samples and three randomly chosen positions (n = 12). Statistics: two-way ANOVA (Mg, Mg–6Ag compared to glass control = #; 24 h, 48 h compared to 0 h = *) with Tukey's multiple comparison test. One symbol = p < 0.05; two symbols = p < 0.01; three symbols p < 0.001; four symbols = p < 0.0001.
