Fig. 2.

Presence of IL-17C in tissues surrounding aseptic loosened implants. Immunofluorescence of human IL-17C was performed on the samples of the aseptic loosening, rheumatoid arthritis and the negative control groups. The anti-human IL-17C antibody was labelled with CY3 (red). The cell nucleus was counter stained with Dapi (blue). Each column contains three different cases suffering from aseptic loosening, rheumatoid arthritis or in the negative control groups. a Samples were the rheumatoid synoviums taken from three different cases. The mean optical density is 755.29, 864.20 and 741.36 from top to bottom. b The samples were the interface membranes surrounding the aseptic loosened implants taken from three different cases. The mean optical density is 953.92, 623.14 and 855.03 from top to bottom. c The samples were negative controls from three different cases. The mean optical density is 272.96, 281.35 and 352.32 from top to bottom
