title: Characterization of glycoconjugates in the bovine endometrium and chorion by lectin histochemistry.
abstract: Lectin binding patterns were examined on normal bovine endometrium and bovine placentomes during four stages of pregnancy using 13 biotinylated lectins. Lectin binding intensity increased in early pregnancy for many lectins, whereas binding to fucosyl residues decreased. Persistence of strong lectin binding later in pregnancy usually was limited to the arcade and intercotyledonary trophoblastic cells. Binding of some lectins to cell surfaces was prominent, particularly in early pregnancy. A few lectins were excellent markers for binucleate trophoblastic cells. These distinctive surface and binucleate cell binding patterns on placentomes and endometrial epithelium are useful markers of trophoblastic cell-endometrial epithelial cell surface interactions and of binucleate cell differentiation.
