Characterization of glycoconjugates synthesized by polarized immature rabbit uterine epithelial (UE) cells in vitro, their vectorial patterns of secretion, and regulation by ovarian steroid hormones are reported. Large (mol wt, greater than 230 kDa) sialomucoglycoproteins and hyaluronate were primarily (86-96%) secreted from the apical cell surface domain, while heparan sulfate proteoglycans were predominantly secreted from the basal cell surface of the polarized UE cells. The polarized UE cells responded to estrogen and progesterone in vitro and exhibited distinct profiles in their synthesis and secretion of different glycoconjugates. Progesterone and/or estrogen reduced the secretion of the mucosialoglycoproteins; however, progesterone caused a 4- to 5-fold accumulation of mucosialoglycoproteins in the cell-associated fraction, suggesting regulation by the hormone at the level of secretion, rather than synthesis. Estrogen and progesterone both stimulated the synthesis and secretion of hyaluronate by the polarized UE cells. Neither hormone substantially altered the synthesis or secretory pattern of heparan sulfate proteoglycans. Collectively, these studies provide the first comprehensive characterization of the major glycoconjugates synthesized and secreted by rabbit UE cells. Furthermore, these observations demonstrate marked differential direct influences of steroid hormones on the production of distinct classes of UE cell glycoconjugates.
