Uterine sarcomas are very unique tumors with mesodermial origin and accounting for 2-6% of uterine cancers. In general, uterine sarcomas are the most malignant tumors of the uterus. Their usual histologic types are endometrial estromal sarcoma, lieomyosarcoma and malignant mixed mullerian tumor or carcinosarcoma In this case report, a 19 year old woman with chief complaint of abnormal ute...

background: the aim of this study was to investigate the percentage of the stem cells population in human endometrial tissue sections and cultured cells at fourth passage. methods: human endometrial specimens were divided into two parts, one part for morphological studies and the other part for in vitro culture. full thickness of human normal endometrial sections and cultured endometrial cells ...

Endometrial stromal sarcomas are rare gynecologic malignancies characterized by the presence of cells that resemble those of the endometrial stroma during the prolipferative phase of the menstrual cycle. They are classified as low grade or high grade tumors depending on the mitotic index, the second one being usually associated with poor prognosis and high recurrence rate. We present the case o...

BACKGROUND GnRH II is the second form of GnRH and is widely distributed in peripheral tissues of the female reproductive tract as well as in the central nervous system. In the present study, we studied the possible implication of GnRH II in endometriosis. METHODS Effects of GnRH II on 5-bromo-2'-deoxyuridine (BrdU) uptake by cultured endometriotic stromal cells were examined. Effects of GnRH ...

There were no significant differences in the distribution of embryos reaching to 2cells, 4cells, morula or blastocysts culturing on human endometrial stromal cells (Secretory or proliferative phases). The percent of morula in stage A (without fragmentation), stage B (<25% fragmentation), stage C (25-50% fragmentation) and stage D (>50% fragmentation) and did not showed significant differences b...

Many efforts have been devoted to establish in vitro cell culture systems. These systems are designed to model a vast number of in vivo processes. Cell culture systems arising from human endometrial samples are no exception. Applications range from normal cyclic physiological processes to endometrial pathologies such as gynecological cancers, infectious diseases, and reproductive deficiencies. ...

During reproductive life, the human endometrium undergoes around 480 cycles of growth, breakdown and regeneration should pregnancy not be achieved. This outstanding regenerative capacity is the basis for women's cycling and its dysfunction may be involved in the etiology of pathological disorders. Therefore, the human endometrial tissue must rely on a remarkable endometrial somatic stem cells (...

Endometrial stromal sarcoma represents a very rare pathological entity occurring as a malignant disease in women genital sphere, frequently in the age group of 40-50 years. Low grade endometrial stromal sarcoma (LGESS) is a rare uterine sarcoma constituting 0.2% of all the uterine malignancies with a good prognosis despite a tendency to recur. We report a case of 42 yr old woman presented with ...

Decidualization of endometrial stromal cells is an important feature of implantation and pregnancy. The molecular mechanism underlying decidualization remains unclear, particularly regarding the microRNA (miRNA/miR) regulation of this process. The present study revealed the temporal and spatial distribution of mmu‑miR‑96 in the mouse uterus during early pregnancy by reverse transcription‑quanti...

PURPOSE The metabolism and synthesis of intratumoral estrogens are thought to play a very important role in the etiology and progression of endometrial carcinoma. Aromatase is a key enzyme in the conversion of androgens to estrogens, and aromatase localization studies have reported that aromatase immunoreactivity and mRNA were detected mainly in stromal cells. However, the effect of tumor-strom...
