Embryo implantation represents the most critical step of the reproductive process in many species. Inadequate uterine receptivity is responsible for approximately two-thirds of implantation failures. The cell adhesion molecule (CAM) such as integrins, cadherins, selectins and immunoglobulins intervene to ensure adhesiveness between the embryo and the endometrium. Some recent studies indicate th...

background: in cancer patients, chemo and radiotherapy can cause infertility by damaging spermatogenesis process. this process is based on self-renewal and differentiation of a rare population of the testicular cells called spermatogonial stem cells (sscs). scientists have tried to isolate, enrich and culture human spermatogonial stem cells, hoping to resolve infertility problems in cancer reco...

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 (...

Human endometrial tissue has become an attractive source of mesenchymal stem cells (MSCs) for cell-based therapies because these MSCs can be easily harvested and have tumour tropism as well as reduced immunogenic and inflammatory properties. Our study aimed to obtain and characterise human endometrial mesenchymal stem cells (EMSCs) and assess their endometriosis tropism. EMSCs were successfully...

STUDY QUESTION Can the basal epithelial compartment of the human endometrium be defined by specific markers? SUMMARY ANSWER Human endometrial epithelial cells from the basalis express nuclear SOX9 and the cell-surface marker SSEA-1, with some cells expressing nuclear β-catenin. In vitro, primary endometrial epithelial cells enriched for SSEA-1+ show some features expected of the basalis epith...

BACKGROUND An effective embryonic-maternal interaction is crucial for successful human pregnancy. Failure of this process is a major cause of infertility and can lead to placental dysfunction resulting in recurrent miscarriage, fetal retardation and pre-eclampsia. Research is severely constrained by ethical and practical considerations; therefore, we aimed to generate cytotrophoblast stem (CTBS...

objective: cell vital function has correlation with mechanical loadings that cell experiences. here, effects of in-vitro combined cyclic-static stretch on proliferation of human mesenchymal stem cell (hmsc) were evaluated. materials and methods: hmscs were cultured on gelatin coated elastic membranes, and exposed to stretch loading. four different regimes of cyclic, static, combined cyclic-sta...

Background: In apoptosis is physiological cell death which eliminates injured and old cells. Any disruption in apoptosis, leads to disease. Resveratrol is a natural polyphenol with estrogen-like, antioxidant and antiinflammatory properties; also it showed cell prolifratory and inhibitory effect. The aim of present study was to determine resveratrol effect on apoptosis of human endometrial epith...

Background: Endometrial carcinoma develops through preliminary stages of endometrial hyperplasia. A population epithelial stem cells was identified in the human endometrium, these may serve as a source putative carcinoma. The most important member cancer cell markers is OCT-4. Both tumor proliferation (Ki-67) and angiogenesis seem to be for development aggressive tumors. Aim Work: This study ai...
