Effect of MPC administration on SF cytokines in sheep with CIA. Concentrations of activin A (A), IL-17A (B), IFN-γ (C) and IL-10 (D), were compared between the MPC-treated and the control group using paired Wilcoxon (left versus right) and unpaired Mann-Whitney (saline versus MPC treatment) tests. Lines represent mean ± SEM of seven to eight sheep and ^* and ^** represent p ≤ 0.05 and 0.01, respectively. IFN interferon, IL interleukin, MPC mesenchymal precursor cells
