Non-specific background proliferation induced by the different serum conditions. T cell proliferation was measured by [³H] thymidine incorporation assay after a 5 day incubation of either CD5⁺ T cells alone (a) or co-incubation of CD5⁺ T cells with non antigen-primed eqMoDC (b). Each symbol indicates a separate horse (n = 6), with red lines indicating the median value. Non-parametric paired sample Wilcoxon (signed rank) tests were used to compare HS with each FBS and p-values ≤ 0.05 were considered statistically significant
