Figure 2From: Expression profiling in spondyloarthropathy synovial biopsies highlights changes in expression of inflammatory genes in conjunction with tissue remodelling genes Immunohistochemistry showing MMP3 protein levels in synovial biopsies. MMP3 was undetectable in normal biopsies (A) with very low levels seen in RA (C) with similarly low levels in SpA (D) samples and high expression of MMP3 in AS samples (B). Quantitation of the stain is shown in (E).Back to article page
