Interleukin-29 Enhances Synovial Inflammation and Cartilage Degradation in Osteoarthritis

Figure 2

The expression and cellular distribution of IL-29 and IL-28Rα in the synovial tissues. IL-29 and IL-28Rα in synovial tissues of OA patients () and HC () were detected by immunostaining (a) and semiquantification (b). Values in (b) are the mean ± SEM. versus medium control. (c) Colocalization of IL-29 with CD68 or FGF-2 in OA synovium was detected by double immunofluorescence staining, and nuclei were counterstained with DAPI. All of the magnification in this figure was ×400.
