Chapter 1 1.1 Chapter 1 13.2.2Ce// actf?es/on mo/eci//es Adhesive properties of endometrial cells determine the process of attachment of retrogradely shed endometrium to the peritoneal lining.Several cell adhesion molecules are expressed by…

Endometriosis is defined as the presence of endometrium outside of uterine cavity and thought to develop through reverse menstruation of endometrial tissue into the peritoneal cavity. Endometrial cell implantation into peritoneal cavity is …

OBJECTIVE: To investigate the regulation of perimenstrual MMP-1 expression in human endometrium. DESIGN: In vitro study utilizing epithelial-stromal co-cultures. SETTING: Cell Biology Unit, International Institute of Cellular and Molecula…

The endometrium is the only human tissue to undergo cyclic breakdown and regeneration. This physiological alternation renders it an advantageous system for studying tissue remodelling. Our previous observations indicate that menstrual endom…

OBJECTIVE: To determine whether interstitial collagenase (matrix metalloproteinase-1), known to play a pivotal role in the initiation of menstruation, contributes to the pathogenesis of endometriosis. DESIGN: Serial sections of peritoneal …

Recent studies suggest that interstitial collagenase (MMP-1) is an essential enzyme in the early events leading to menstruation. This study analyses its cellular origin, regulation and relation to extracellular matrix breakdown in the human…

Collagenases are the only mammalian enzymes able to cleave, at neutral pH, the triple helical domain of fibrillar collagens, major constituents of the extracellular matrix of the endometrium. Interstitial collagenase is expressed, secreted …

Human endometrial tissue, sampled at different periods of the reproductive cycle, expressed interstitial collagenase mRNA, protein and activity only just before and during the menstrual period. This clear-cut correlation and the inhibition …
