OBJECTIVE: Transplantation of adipose-derived stem cells (ADSCs) is associated with potential risks of late complications including tumorigenesis due to the active proliferation of the cells. We aimed to test the effect of transplantation of ADSCs with suppressed proliferation by gamma irradiation in the treatment of thin endometrium in rats. METHODS: ADSCs were isolated from female SD rats and identified by detecting the surface antigens with flow cytometry. After exposure to gamma irradiation at 0, 5 Gy and 10 Gy, the cells were examined for changes in colony-forming ability...

Reproductive failure in humans is a very important social and economic problem, because nowadays women decide to conceive later in life and delay motherhood. Unfortunately, with increasing age they have less chance for natural fertilization and maintenance of pregnancy. Many of them need assisted reproductive technology. Approximately 10% of women after in vitro fertilization-embryo transfers experience recurrent implantation failure (RIF). Multiple factors may contribute to RIF, including oocyte and sperm quality, parental chromosomal anomalies, genetic or metabolic abnormalities of the embryo, poor uterine receptivity, immunological disturbances in the implantation site, and some gynecologic pathologies such as endometriosis, uterine fibroids, hydrosalpinx and endometrial polyps...

Endometrial cells and microenvironment are two important factors in the pathogenesis of adenomyosis. Our previous study demonstrated that macrophages can induce eutopic epithelial cells of adenomyosis suffering from epithelial-mesenchymal transition (EMT). The aim of this study is to detect whether macrophages interacting with epithelial cells equally induce the EMT process in normal and eutopic endometria of healthy and adenomyotic patients; and macrophages parallelly polarize to M2. We investigated expressions of epithelial cadherin (E-cadherin), neural cadherin (N-cadherin), cytokeratin7 (CK7), vimentin, transforming growth factor-β1 (TGFB1), SMAD3 and pSMAD3 using Immunohistochemistry and Western Blot, then estimated genetic levels of CD163, IL10 and MMP12 using real-time quantitative polymerase chain reaction (RT-PCR) in macrophages...
