  1. Supernatants were collected after 18 hours with or without IL-12 (100 ng/ml) incubation (Data represent the mean (ng/ml) ± SEM of n = 4–10 independent experiments). Results expressed as means (ng/ml) ± SEM, n = 4–10, ***p < 0.001 compared with co-cultures without IL-12 treatment, ANOVA with Bonferroni's multiple comparison test.
