Immunohistochemistry staining shows a vascular endothelial growth factor-A (VEGF). b CD31 expressions in the synovial membranes collected from normal human and rheumatoid arthritis (RA) patients. c CD31 expressions are significantly increased in human RA synovial membranes (data are expressed as mean ± SEM, *P < 0.05 versus normal, Student’s t test.). Scale bar = 100 μm. The figure is a representative image from 6 normal and 6 RA patients with similar results
