BACKGROUND The animal models of endometriosis could be a valuable alternative tool for clarifying the etiology of endometriosis. OBJECTIVE In this study two endometriosis models at the morphological and molecular levels was evaluated and compared. MATERIALS AND METHODS The human endometrial tissues were cut into small fragments then they were randomly considered for transplantation into γ i...

p50 is a member of the NF-kappaB family known to be involved in endometriosis. To gain insight into the roles of p50 in the development of endometriosis, we cross-transplanted endometrial fragments from p50 knockout mice to wild-type mice and vice versa, and also autotransplanted the fragments within the knockout and wild-type mice, inducing endometriosis. We then evaluated the size of the endo...

The pattern of constitutive and cycle-dependent integrins in normal endometrium has recently been established, suggesting a role for cell adhesion molecules in endometrial receptivity and implantation. Currently few, if any, models exist for the study of human endometrial integrins and their role in establishment of the receptive endometrial phenotype. The Ishikawa cell line maintains functiona...

Acquisition of functional receptivity by the endometrium is assumed to be effected by progesterone-dependent expression and repression of several genes during the implantation window in a menstrual cycle. In the present study, we employed differential display (DD) reverse transcription-polymerase chain reaction (RT-PCR) to identify progesterone-dependent gene/gene fragments that are differentia...

OBJECTIVE Early detection and diagnosis of endometrial carcinoma and precancerous change would undoubtedly become the most alluring part for researchers. With the emergence of endometrial brush samplers, a new upsurge in endometrial cytology is in the making. But endometrial specimens obtained by the endometrial brush samplers require special preservation solution. The objective of this study i...

Objective To compare the diagnostic suitability of endometrial tissues obtained from postmenopausal women using the MyoSure Lite tissue removal system versus conventional curettage. Materials and methods Endometrial tissue was sampled in hysteroscopically normal extirpated uteri from seven postmenopausal women (65.9±6.6 years old) using both hysteroscopicguided morcellation and curettage (two...

OBJECTIVE Most endometrial cancers are detected early and have a good prognosis, while some endometrial cancers are highly invasive, metastasize early, and respond suboptimally to therapy. Currently, appropriate model systems to study the aggressive nature of these tumors are lacking. The objective of this study was to establish a mouse xenograft model of endometrial tumors derived from patient...

Amniotic membrane-derived mesenchymal cells (AMCs) are considered suitable candidates for a variety of cell-based applications. In view of cell therapy application in uterine pathologies, we studied AMCs in comparison to cells isolated from the endometrium of mares at diestrus (EDCs) being the endometrium during diestrus and early pregnancy similar from a hormonal standpoint. In particular, we ...

BACKGROUND Pelvic endometriotic lesions are often laden with hemosiderin. In order to investigate the potential source of such iron deposits, we examined whether the seric and erythrocyte fractions of menstrual effluent might influence the occurrence of iron deposition within lesions in a murine model of endometriosis. METHODS Endometriosis was induced in 57 nude mice by intraperitoneal injec...
