Figure 7From: Expression of ADAM15 in rheumatoid synovium: up-regulation by vascular endothelial growth factor and possible implications for angiogenesisCorrelation between ADAM15 mRNA expression levels and vascular density in synovial tissues. Vascular density was determined by the morphometric analysis of the CD31-immunostained sections and correlation was examined by Spearman's rank correlation. Note a direct correlation between the parameters (r = 0.907, p < 0.001; n = 20). Open and closed circles indicate osteoarthritis (OA) and rheumatoid arthritis (RA) synovial samples, respectively.Back to article page
