It was assumed that uterine stem cells are responsible for the unique regenerative capacity of uterine. Therefore, the aim of the present study was to investigate the expression of the pluripotent stem cell markers in the mice uterine tissue during different stages of estrous cycles. Twelve virgin female NMRI mice (6 to 8 weeks old) were considered at proestrus, estrus, metestrus and diestrus a...

Since the classical studies of Grosser1" the classification of mammalian placental types has been based upon the number of tissue layers separating the maternal vascular system from the fetal vessels and across which the diffusable materials essential to intrauterine development must move from the maternal to the fetal plasma. Grosser's classification is based on the concepts: (i) that in phylo...

Endometriosis is defined by the presence of ectopic endometrial tissue outside the uterine cavity. Despite being a lead cause of chronic pelvic pain and infertility, its clinical presentation can vary, leading to diagnostic and therapeutic challenges. Extra-pelvic endometriosis is particularly difficult to diagnose owing to its ability to mimic other conditions. Endometrial tissue in a surgical...

the present study evaluate the histopathologic findings and clinical indications in hysterectomized patients based on sonographic assessments. this study population consisted of all patients who were referred to the pathology ward of imam reza educational and treatment center (kermanshah, iran) during march 2006 to may 2012. the samples were stained with hematoxylin-eosin after fixation in form...

To study the temporal relationship between changes in hormone levels with the development of myometrial gap junctions, rats were sacrificed to collect uterine vein blood and uterine tissues daily from Day 15 to Day 20 of pregnancy, every 3 h on Day 21, during delivery, and 3 h after parturition. Levels of progesterone, estradiol and prostaglandin F2 alpha (PGF2 alpha) were measured by specific ...

Endometriosis is a common disease with typically delayed diagnosis. Its prevalence high among adolescents pelvic pain symptom. Deposits of tissue outside uterine cavity depend on oestrogen. Progestins and oral contraceptives are not successful 1/3 symptomatic women worldwide. Pathogenesis endometriosis well understood but immune system plays role in its pathophysiology. The aetiology remains la...

The effect of altering uterine space available to developing conceptuses on placental and endometrial protein secretion and endometrial 3 H-thymidine incorporation on Days 25 and 35 of gestation was tested. Gilts bred at estrus (Day 0) were laparotomized on Day 4, and the uterine horn ipsilateral to the ovary with the most ovulations was ligated midway between the uterine tip and uterine bifurc...
