The chick embryo chorioallantoic membrane (CAM) bioassay was used to investigate the early pathogenesis of endometriosis. Endometrial fragments were explanted onto the CAM. The grafts including the surrounding CAM were excised at 24, 48 or …

Sampson's transplantation theory for the pathogenesis of peritoneal endometriosis is widely accepted. The events that take place, however, on the cellular and subcellular level during the transition of endometrial tissue in the abdominal ca…

Previous in-vitro studies have shown that the endometrium preferentially adheres to the extracellular matrix (ECM) of the amnion and peritoneum. This interaction probably involves adhesion molecules, e.g. integrins. We evaluated the express…

In a previous study on the pathogenesis of endometriosis, we observed that constituents of menstrual effluent induce morphological alterations in human mesothelial cells. In this study, we investigated whether these alterations were associa…

OBJECTIVE: To evaluate the adhesion of endometrial fragments obtained during the proliferative phase of the menstrual cycle to fresh human peritoneum obtained during abdominal surgery. DESIGN: A prospective, descriptive, morphologic and ce…

One of the first steps in the pathogenesis of endometriosis is the attachment of the endometrium to the peritoneal lining. Since the peritoneum is extremely fragile and hard to obtain, amnion has been used as an in-vitro model to study adhe…

Reproductive research benefits from combining animal and clinical studies. In Leuven, rabbits have constituted an animal model for many reproductive disorders, especially for those that involved surgical treatment. Much of what has been lea…

OBJECTIVE: Our purpose was to examine the immunohistochemical properties of epithelial cells in peritoneal fluid and to compare the staining characteristics with cells of endometrium, menstrual effluent, peritoneum, and endometriotic lesion…

OBJECTIVE: To detect cadherin and integrin expression in biopsies of endometrium in the phases of the cycle. Cell adhesion molecules may be involved in endometrial shedding during menstruation and attachment of shed endometrial tissue to th…

Screening for endometriosis is subject to general rules. The two most important conditions, i.e. the disorder should be well-defined and serious, and there must be an effective way to treat or prevent it through screening, are not satisfied…
