- Abstract
Hyaluronate is actively synthesized by cultured epidermis and dermis, but no direct histological data have been available about its localization in normal human skin. A hyaluronate-specific biotinylated probe, prepared from the hyaluronate binding region of cartilage proteoglycan, was applied to human skin sections and visualized using the biotin-avidin-peroxidase system. The specificity of this staining was confirmed by hyaluronidase predigestion and by hyaluronate-derived oligosaccharides added to the staining solution. All dermis showed diffuse binding of the probe, but the highest staining intensity was observed in the epidermal intercellular spaces. The stainability extended from basal cells to the middle layers of the epidermis, whereas the granular layer and stratum corneum were completely negative. Also, the basal side of basal cells (basement membrane) did not bind the hyaluronate probe. The abundance of hyaluronate on surfaces and intercellular spaces of the spinous cells is suggested to have an important role in the physiology of human epidermis.
