D IL-1β E IL-6 and F IL-8 for anti-inflammatory assay (see also Additional file 1: File 10). (Data are means ± SEM of three individual experiments. ^*p < 0.05 ^**p < 0.01 ^***p < 0.001, ^****p < 0.0001, One-Way ANOVA, Bonferroni’s multiple comparison test; each group mean vs the mean of Control ⁻). In both conditions, Control ⁻ denotes no treatment, media change and Control ⁺ denotes LPS incubation (100 ng/ml)
