Mice (n = 15 in each group) were injected i.a. with 1 U/mouse of collagenase on Day 0 and Day 2. Synovial extract was collected separately from each animal at Day 7 of CIOA and the level of several mediators was determined by ELISA; Student's t-test; ***P < 0.001 vs healthy mice.

CIOA, collagen-induced osteoarthritis; ELISA, enzyme linked immunosorbent assay; IL, interleukin; MIP-1α, macrophage inflammatory protein 1α; sRANKL, soluble receptor activator of nuclear factor kappa B ligand; RANTES, regulated upon activation, normal T-cell expressed, and secreted protein; TNF, tumor necrosis factor.
