Abstract
Polyclonal antibodies against the core protein of the small chondroitin sulfate-dermatan sulfate proteoglycan from human skin fibroblast secretions were used, after affinity-purification, as a probe to study localization of crossreactive material in several human tissues by indirect immunocytochemistry. In contrast to skin, kidney, and the adventitial layer of aorta, positive staining of brain, liver, cartilage, and intimal and medial layers of aorta required pre-treatment of tissue sections with chondroitin ABC lyase. In all tissues investigated, antigenic material was present in the interstitial space. Filamentous structures were perpendicularly oriented towards basement membranes. In liver, specific staining was seen along the sinusoidal walls. Reticular fibers with or without focal condensations were seen in cerebral cortex and cerebellum. The results suggest a role of small chondroitin sulfate-dermatan sulfate proteoglycan in cell-matrix interactions.
