Interleukin-29 Enhances Synovial Inflammation and Cartilage Degradation in Osteoarthritis

Figure 3

Immunostaining for IL-28Rα in OA fibroblasts and viability of OA FLS in response to IL-29. The expression of IL-28Rα in OA FLS, detected by immunofluorescent staining (a) and flow cytometric analysis (b). The magnification in (a) was ×400. (c) OA FLS viability after being incubated with IL-29 at 1, 10, and 100 ng/mL for 72 h was measured by MTT assay. The data present the mean ± SEM of three independent experiments.
