To understand the association of LRG1 and atherosclerosis, paraffin-embedded sections of non-stenotic (n = 3) and stenotic (n = 6) coronary artery were stained with Elastic van Gieson stain (EVG) and anti-CD31 and anti-LRG1 antibodies (Figure 1A). The gene discussed is PECAM1; the disease is atherosclerosis.
