TIGHT JUNCTIONS IN THE GLANDULAR EPITHELIUM OF NORMAL HUMAN ENDOMETRIUM / 解剖学报

ABSTRACT

Freeze-fracture technique was used to study the tight junctions in the glandular epithelium of normal human endometrium at different phases of the menstrual cycle. The tight junctions were consisted of a few strands and extended less deeply along the lateral plasma membrane during the early proliferative phase of the cycle.The number of strands, but not the depth of the tight junctions, significantly increased (P0.05) during the late proliferative phase and early secretory phase as compared to the mid-proliferative phase. During the midsecretory phase, the number of strands as well as tight junctional depth significantly increased(P
