In order to assess the possible utility of lectin binding to identify the cellular components of fixed arterial lesions we studied lectin binding in experimental rabbit and monkey vessels, as well as in human atherosclerotic arteries obtained at surgery. The avidin-biotin-peroxidase technique was used to localize the binding of the following biotinylated lectins: Concanavalin A (Con A), Dolicho biflorus agglutinin (DBA), soybean agglutinin (SBA), peanut agglutinin (PNA), Phaseolus vulgaris agglutinin (PHA), Ricinus communis agglutinin (RCA), wheat germ agglutinin (WGA), and Ulex europaeus agglutinin (UEA). PHA demonstrated specific cytoplasmic staining of macrophages in rabbit, monkey, and human tissues and differentiated macrophages from other cell types in atherosclerotic lesions. When morphometric comparisons were made between lesion PHA staining and another macrophage marker, acid lipase, very similar results were obtained. Con A, RCA, and WGA stained macrophages intensely and differentiated them from other cell types in normal reticuloendothelial tissues and lesions, but also stained smooth muscle cells and endothelial cells when these cells developed lipid vacuoles. UEA stained the endothelium of vasa vasorum consistently in human arteries, but staining of artery lumen endothelium was variable. Endothelial cells of rabbit or monkey vessels did not stain with UEA. DBA, PNA, and SBA did not consistently stain any cellular structures in arteries. PHA was found to be an excellent marker to differentiate and quantify macrophages in glutaraldehyde or formalin-fixed, paraffin-embedded experimental and human atherosclerotic lesions. Con A, RCA and WGA merit further detailed study in conjunction with other histochemical tests as possible markers of functional changes in arterial cells during lesion development.
