Fig. 4From: Evaluation of antigen-induced synovitis in a porcine model: Immunological, arthroscopic and kinetic studiesDistribution of synovial lymphocyte subsets. Synovial fluid lymphocytes were collected for flow cytometric analysis just before intra-articular injection (basal) and 7 days after. The graphic shows the percentage of CD4+ T cells (a) CD8+ T cells (b) and their ratio c. Values show the mean ± SD (n = 3). *Statistically significant difference (p ≤ 0.05) compared to basal levelBack to article page
