[Detection of fibronectin and collagen types I, III, IV and V in semithin sections of the human aorta].
Localization of fibronectin and types I, III, IV and V collagen was investigated in semithin sections of fibrous atherosclerotic plaques and apparently normal intima of human aorta. The effect of different techniques of fixation and processing of the sections on immunostaining under peroxidase-antiperoxidase techniques have been examined. The tissue fixation in paraformaldehyde solution, removing the resin with sodium ethoxide and enzymatic pronase digestion of the sections resulted in successful specific staining of the antigens. It was found that some cells in fibrous plaques formed a cap of multiple layers of dense connective tissue containing fibronectin and type III, IV and V collagen in the absence of collagen type I.
