THE OBSERVATION OF ULTRASTRACTURAL LOCALIZATION OF ALKALINE PHOSPHATASE IN CANCEROUS AND PRECANCEROUS ENDOMETRIUM / 西安交通大学学报(医学版)

ABSTRACT

Ultrastructural localization of alkaline phosphatase (AKP) was observed with histochemical method in 10 cases of endometrium. AKP was localized on plasma membranes of glandular cells in normal proliferative and adenomatous hyperplastic endometrium. Uhrastractural、locatization of AKP has no significant change in endometrial cancer. In differentiated endometrial cancer AKP was predominantly localized on microvilli and apical plasma membranes of tumor cells which were adjacent to glandular cavity; and in undifferentiated cancer AKP was evenly distributed on plasma membaanes of tumor cells.
