Histochemistry of the lumenal cell surfaces of the mucosa of the oviducts and the uterus of the rat. Changes in prepuberty, estrous cycle, castration, hormone replacement and pseudopregnancy.

The lumenal surface coat of the rat oviducts and uterine horns have been histochemically characterized at prepuberty, estrous cycle, castration, hormone replacement and pseudopregnancy. Under the EM, the coat was made up of filamentous and globular structures. Histochemical variations suggested that coat components are under endocrine control.
