background: endometriosis is the presence of endometrial glandular and stromal cells outside of the uterine cavity. our previous study showed that in vitro culture of human endometrial tissue in a three-dimensional (3d) fibrin matrix could mimic the early stages of endometriosis with invasion gland and stroma formation and sprouting of new vessels. objective: the objective of the present study ...

BACKGROUND/AIMS Tolerance of T lymphocytes at the feto-maternal interface is necessary to sustain normal pregnancy. The present investigation aimed to observe the regulatory effects on T lymphocytes by human trophoblasts and to explore possible effector molecules. METHODS Conditioned media was made by trophoblast culture or villous explant culture for T lymphocyte proliferation and proteomic ...

In primates, the phase of the menstrual cycle when the uterus becomes receptive is initially dependent on estrogen and progesterone. Further morphological and biochemical changes are induced as a result of biochemical signals between the embryo and the maternal endometrium. Blastocyst implantation in the baboon usually occurs between 8 and 10 days post ovulation and is similar to that described...

BACKGROUND The maternal circulation to the human placenta is not fully established until 10-12 weeks of pregnancy. During the first trimester the intervillous space is filled by a clear fluid, in part derived from secretions from the endometrial glands via openings in the basal plate. The aim was to determine the activity of the glands throughout the first trimester, and to identify components ...

BACKGROUND The progesterone-regulated glycoprotein glycodelin-A (GdA), secreted by the decidualized endometrium at high concentrations in primates, inhibits the maternal immune response against fetal antigens and thereby contributes to the tolerance of the semi-allogenic fetus during a normal pregnancy. Our earlier studies demonstrated the ability of GdA to induce an intrinsic apoptotic cascade...
