title: Localization of nucleoside phosphatases (ATPase and 5'-nucleotidase) and nuclear ribonucleoproteins in the human endometric glandular cells during the secretory phase.
abstract: Endometrial curettings from 3 healthy women between 16th and 19th d of the menstrual cycle were investigated employing ultracytochemical methods. In endometrial glandular cells ATPase and 5'-nucleotidase activities were demonstrated in the nuclei, nucleoli, and nuclear channel system (NCS), i.e., mainly in structures characterized ++as ribonucleoproteins according to the Bernhard method. The functional relationship between the NCS and the molecular biology of the endometrial glandular cell is discussed.
