Figure 6. Dose-response of gingival fibroblasts from the young (black squares) and the older (white circles) donor to increasing doses of latex extracts (mg/mL), as measured by XTT assay. Results are reported as mean±SD of quintuplicates, normalized as a percentage of the control group (unexposed cells). Latex concentration is represented on a log 10 scale. The lines represent the logistic regression fit for each curve, performed with Graphpad Prism 6.0.
