Mammalian uterus contains a population of mesenchymal stem/progenitor cells that likely contribute to endometrial regeneration during each reproductive cycle. In human and mouse, they reside in perivascular, epithelial and stromal compartments of the endometrial functionalis and basalis. Here, we aimed to identify tissue resident cells expressing mesenchymal stem cell markers CD29, CD44, CD90, CD105, CD140b and CD146 in the porcine endometrium. We used single immunofluorescence and Western blotting. Each of these markers was detected in small cells surrounding endometrial blood vessels...

Endometrial stem cells take the special place among somatic stem cells of female reproductive system, since their essence and nature still remains unclear - cellular complexity of endometrium, its hormone-dependence and cycling remodeling makes the study of endometrial stem cells exclusively complicated. Consequently, the detection of endometrial stem cells and identification of their location in the complex cellular hierarchy still remains challenging. The aim of our study was to explore the age-related specificities of endometrial proliferative / stem cell index distribution under normal and hyperplasia conditions...

Endometriosis is defined by presence of endometrial-like-tissue outside the uterus. Recently, ectopic endometriotic lesions have been suggested to originate by abnormal differentiation of endometrial mesenchymal stem cells (eMSCs). MicroRNAs (miRNAs) play an important role in the pathophysiology of endometriosis. Through a PCR array approach, we aimed to assess the differential expression of microRNAs in human eMSC treated in culture with sera derived from women with severe endometriosis. Sera were collected from five patients with severe endometriosis and three control women and added individually in the culture medium to conduct experimental and control eMSC sets, respectively...

Stem cells are recruited to the uterus where they differentiate into endometrial cells and have been suggested as potential therapy for uterine injury such as Asherman's syndrome. However, it is unknown whether local intrauterine injection may result in better stem cell engraftment of the uterus compared with systemic administration, and whether uterine-derived cells (UDCs) may confer an advantage over BM-derived cells (BMDCs). Mice underwent local injury to a single uterine horn. Green fluorescent protein (GFP)-expressing BMDCs, UDCs or saline (control) were injected either intravenously or locally (uterine lumen) into wild-type recipients...

BACKGROUND: Equine mesenchymal stromal/stem cells (MSCs) are most commonly harvested from bone marrow (BM) or adipose tissue, requiring the use of surgical procedures. By contrast, the uterus can be accessed nonsurgically, and may provide a more readily available cell source. While human endometrium is known to harbor mesenchymal precursor cells, MSCs have not been identified in equine endometrium. This study reports the isolation, culture, and characterization of MSCs from equine endometrium...

Pregnant nulliparous adolescents are at increased risk, inversely proportional to their age, of major obstetric syndromes, including preeclampsia, fetal growth restriction, and preterm birth. Emerging evidence indicates that biological immaturity of the uterus accounts for the increased incidence of obstetrical disorders in very young mothers, possibly compounded by sociodemographic factors associated with teenage pregnancy. The endometrium in most newborns is intrinsically resistant to progesterone signaling, and the rate of transition to a fully responsive tissue likely determines pregnancy outcome during adolescence...

We have earlier reported the presence of very small embryonic-like stem cells (VSELs) in adult mouse uterus along with slightly bigger progenitors termed endometrial stem cells (EnSCs) and their regulation by ovarian hormones thus demonstrating a crucial role played by them during proliferation, differentiation and remodeling of the endometrium. Present study is a brief communication wherein we have examined the effect of higher dose of estrogen (E, 2 μg/day), progesterone (P, 1 mg/day) and follicle stimulating hormone (FSH, 5 IU/day for 5 days) specifically on the myometrium and perimetrium surrounding the endometrium in bilaterally ovariectomized mice...

Adult stem cells have a major role in endometrial physiology, remodeling, and repair, but they also have a critical role in the development and progression of endometriosis. Bone marrow-derived stem cells (BMDSCs) engraft eutopic endometrium and endometriotic lesions, showing stromal and epithelial fate. Nevertheless, circulating BMDSCs are in limited supply, and the presence of endometriosis depletes stem cells from the blood circulation, preventing their homing in the uterus. Furthermore, stem cells migrate from endometriotic lesion into the uterus, leading to a dysfunctional endometrium...

Endometriosis is an inflammatory gynecological disorder caused by the growth of endometrial tissue outside the uterus. Endometriosis produces chemokines, including CXCL12, that attract bone marrow cells to the lesions. In this study, we describe the expression, localization, and chemotactic activity of CXCL12 in endometriotic lesions. Biopsies were collected both from women with endometriosis undergoing laparoscopy and control endometrium from women without endometriosis. Expression of CXCl12 and CXCR4 messenger RNA was increased approximately 4- and 6-fold, respectively, in endometriosis compared to eutopic endometrium...

Studies in human and mouse have shown that decidual stromal cells (DSC), which develop in the innermost lining of uterus, mediate placentation by regulating maternal immune response against the fetus and the extent of fetal invasion. Investigating when and how DSC evolved is thus a key step to reconstructing the evolutionary history of mammalian pregnancy. We present molecular evidence placing the origin of DSC in the stem lineage of eutherians (extant placental mammals). The transcription factor forkhead box O1 (FOXO1) is a part of the core regulatory transcription factor complex (CoRC) that establishes the cell type identity of DSC...

BACKGROUND: Endometriosis is a commonly-encountered gynecological disease characterized by the presence of endometrial glandular and stromal cells outside of the uterus. Several studies have been conducted on endometriosis, however its molecular mechanism and pathogenesis are still not completely clear. The role of ELAM-1 gene in mediating the adhesion of tumor cells to endothelial cells by binding to ELAM-1 ligands expressed by eosinophils, neutrophils, monocytes, natural killer cell effectors, T lymphocyte cells, and cancer (progenitor/stem) cells is well studied...

Bone marrow (BM)-derived cells (BMDCs) contribute to endometrial regeneration. Our objective was to develop a nongonadotoxic mouse BM transplant (BMT) model using 5-fluorouracil (5-FU) for investigating BMDCs trafficking in reproduction. Female C57BL/6J mice received either single (CTX-1) or paired (CTX-2) 5-FU (150 mg/kg) dose, or single (CTX-1+SCF) or paired-dose (CTX-3+SCF) 5-FU with stem cell factor (SCF). Control mice received BMT only or saline. BM cells (20 × 10(6)) from transgenic green-fluorescent protein (GFP) mice were injected iv...

Stuart J Emmerson, Caroline E Gargett
Pelvic organ prolapse (POP) occurs when the pelvic organs (bladder, bowel or uterus) herniate into the vagina, causing incontinence, voiding, bowel and sexual dysfunction, negatively impacting upon a woman's quality of life. POP affects 25% of all women and results from childbirth injury. For 19% of all women, surgical reconstructive surgery is required for treatment, often augmented with surgical mesh. The surgical treatment fails in up to 30% of cases or results in adverse effects, such as pain and mesh erosion into the bladder, bowel or vagina...

UNLABELLED: SummaryHuman endometrium is a highly regenerative tissue, undergoing more than 400 cycles of proliferation, differentiation, and shedding during a woman's reproductive life. Adult stem cells, including mesenchymal stem/stromal cells (MSCs), are likely responsible for the immense cellular turnover in human endometrium. The unique properties of MSCs, including high proliferative ability, self-renewal, differentiation to mesodermal lineages, secretion of angiogenic factors, and many other growth-promoting factors make them useful candidates for cellular therapy and tissue engineering...

Uterine leiomyomas, also known as uterine fibroids or uterine myomas, are the most common benign gynecologic tumors found in women of reproductive age. In spite of the numerous published studies evaluating the hormonal dependency, epidemiology, molecular biology, pathology, and genetics of leiomyomas, many questions remain unanswered. The remodeling of the uterus in response to hormonal stimuli and its return to a basal state may be related to adult stem/progenitor cells residing in the endometrial and myometrial layers...

Endometriosis is a frequent gynecologic disease with a complex, multifactorial cause. It is characterized by the cyclic estrogen-driven proliferation and bleeding of endometriotic lesions (ie, ectopic endometrial glands and stroma) outside the uterus. These lesions induce a chronic activation of the innate immune system within the peritoneal cavity that is associated with the release of various inflammatory cytokines and angiogenic growth factors into the peritoneal fluid. This stimulates angiogenesis and the further spread of the lesions and triggers the typical pain that is symptomatic of the disease...

Endometriosis is the hormone-dependent product of endometrial tissue found outside the uterus. Recently, micro-RNAs (miRNAs) were shown to play a role in endometriotic lesion development. However, the mechanism of steroid hormones responsible for miRNA remains obscure. In the present study, we assayed for the effects of synthetic steroid hormones (danazol, progesterone, and medroxyprogesterone acetate [MPA]) on miRNAs in endometriosis. We used a global miRNA expression profile microarray to evaluate miRNA expression in endometrial mesenchymal stem cells (EN-MSCs) of ovarian endometrioma following treatment with 1 μM danazol, progesterone, or MPA...
