Fig. 4. Percentage of foci generation (Foci %) in the Balb/c 3T3 cellular transformation assay (RCFEs were divided over the Control/Control condition of the respective day and multiplied by 100). (A) Cellular transformation foci analysis on day 16 of the assay from cultures treated with the metal mixture as an initiator and promoter stimulus, compared to the control condition (Control/Control).n=2, mean±s.e., one-way ANOVA F(5,6)=49043 *p<0.0001, Tukey post-hoc comparisons of the groups 95% CI. (B) Relative colony formation efficiency (RCFE) of Balb/c 3T3 cells on day 16, for cells treated with the metal mixture as initiator and promoter stimulus,. n=2, mean±s.e., two-tailed un paired t-test, *p<0.05.
