Abstract Study question What are the characteristics of leptin receptor (LepR) expressing cells within endometrial mesenchymal stromal/stem (eMSCs) population? Summary answer LepR+ eMSCs display better stem-cell capacities as well distinctively quiescent properties compared to and LepR- eMSCs. is known already Single-cell RNA sequencing (scRNA-seq) reveals that cultured heterogeneous. LepR high...

Abstract Study question Does HIF-2α play a key role in pre-menstrual conditioning of the non-pregnant endometrium to optimise menstrual breakdown/repair and prevent heavy bleeding (HMB)? Summary answer HIF-2 was higher secretory women with HMB versus controls, but manipulation mouse model did not impact endometrial breakdown/repair. What is known already Hypoxia inducible factor (HIF) master re...

Background: Nicotine exposure causes impaired fertility , ovarian and uterus dysfunction. The pineal hormone melatonin is known as an antioxidant agent. The aim of this study was to investigate the possible protective role of exogen melatonin on altered ovary and endometrium with nicotine. Materials and Methods: Female adult NMRI mice were divided into four groups. The control group received ve...

There is now strong evidence that many of the actions of steroids in controlling reproduction are mediated by locally acting factors such as growth factors and cytokines. These have been shown to act both in an autocrine and paracrine manner to regulate preimplantation embryo development and migration which is necessary for placental development. The creation of mouse strains lacking genes for ...

The uterine expression of leukemia inhibitory factor (LIF) is essential for embryo implantation in the mouse. Here, we describe the expression of LIF, related members of this group of cytokines, oncostatin M and ciliary neurotrophic factor, and the LIF receptor beta and glycoprotein gp130 in normal human tissues and in the endometrium of fertile women. Our results show that LIF is the only one ...

Background: Acceptance of uterus and reaction between endometrium and embryo has an important role for implantation. Muc1, an integral membrane mucin, is expressed on the apical surface of uterine epithelial cells and could have effects on its receptivity. Objective: The aim of this study was to evaluate the changes in Muc1 expression of gravid mouse endometrium with and without hyperstimulatio...
