The distribution patterns of rat and mouse uterine glycosaminoglycans (GAGs), as well as their modulation by estradiol (E2) and/or progesterone (P), were investigated using monoclonal antibodies (MABs) directed against chondroitin- (CS)/dermatan sulfates (DS), keratan sulfate (KS) and a trophoblast GAG. The localization of GAGs in relation to collagens (I, IV and VI) and fibronectin was also analyzed. We found that uterine GAGs are differentially distributed in the endometrium and myometrium, in a pattern that is species-related. CS-containing proteoglycans (PGs) occur between collagen bundles and fibroblasts, at the periphery of the latter, and in basement membrane zones (BMZs), in a pattern resembling that of collagen VI. BMZs contain preferentially CS-PGs bearing 4-sulfated disaccharides adjacent to the core protein. DS-PGs are mostly associated with collagen bundles. E2 and/or P elicit distinct modifications on the above described pattern, which are also species-related. The simultaneous administration of E2 and P changes the prevalent sulfation of the disaccharides adjacent to the core protein of stromal CS-PGs. In the mouse, an unsulfated intracellular epitope appears following E2 (or E2P) administration, mostly in epithelial cells. In the rat, KS and the trophoblast GAG are E2-dependent and down-regulated by P. The functional significance of the hormone-induced GAG changes, namely the possible role of the E2-dependent KS in implantation, are discussed.
