The period from onset of one menstrual bleeding (MENSTRUATION) to the next in an ovulating woman or female primate. The menstrual cycle is regulated by endocrine interactions of the HYPOTHALAMUS; the PITUITARY GLAND; the ovaries; and the genital tract. The menstrual cycle is divided by OVULATION into two phases. Based on the endocrine status of the OVARY, there is a FOLLICULAR PHASE and a LUTEAL PHASE. Based on the response in the ENDOMETRIUM, the menstrual cycle is divided into a proliferative and a secretory phase.
The hollow thick-walled muscular organ in the female PELVIS. It consists of the fundus (the body) which is the site of EMBRYO IMPLANTATION and FETAL DEVELOPMENT. Beyond the isthmus at the perineal end of fundus, is CERVIX UTERI (the neck) opening into VAGINA. Beyond the isthmi at the upper abdominal end of fundus, are the FALLOPIAN TUBES.
The hormone-responsive glandular layer of ENDOMETRIUM that sloughs off at each menstrual flow (decidua menstrualis) or at the termination of pregnancy. During pregnancy, the thickest part of the decidua forms the maternal portion of the PLACENTA, thus named decidua placentalis. The thin portion of the decidua covering the rest of the embryo is the decidua capsularis.
The major progestational steroid that is secreted primarily by the CORPUS LUTEUM and the PLACENTA. Progesterone acts on the UTERUS, the MAMMARY GLANDS and the BRAIN. It is required in EMBRYO IMPLANTATION; PREGNANCY maintenance, and the development of mammary tissue for MILK production. Progesterone, converted from PREGNENOLONE, also serves as an intermediate in the biosynthesis of GONADAL STEROID HORMONES and adrenal CORTICOSTEROIDS.
RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.
Contraceptive Agents, Female
Specific proteins found in or on cells of progesterone target tissues that specifically combine with progesterone. The cytosol progesterone-receptor complex then associates with the nucleic acids to initiate protein synthesis. There are two kinds of progesterone receptors, A and B. Both are induced by estrogen and have short half-lives.
A pair of highly specialized muscular canals extending from the UTERUS to its corresponding OVARY. They provide the means for OVUM collection, and the site for the final maturation of gametes and FERTILIZATION. The fallopian tube consists of an interstitium, an isthmus, an ampulla, an infundibulum, and fimbriae. Its wall consists of three histologic layers: serous, muscular, and an internal mucosal layer lined with both ciliated and secretory cells.
A progestational and glucocorticoid hormone antagonist. Its inhibition of progesterone induces bleeding during the luteal phase and in early pregnancy by releasing endogenous prostaglandins from the endometrium or decidua. As a glucocorticoid receptor antagonist, the drug has been used to treat hypercortisolism in patients with nonpituitary CUSHING SYNDROME.
The development of the PLACENTA, a highly vascularized mammalian fetal-maternal organ and major site of transport of oxygen, nutrients, and fetal waste products between mother and FETUS. The process begins at FERTILIZATION, through the development of CYTOTROPHOBLASTS and SYNCYTIOTROPHOBLASTS, the formation of CHORIONIC VILLI, to the progressive increase in BLOOD VESSELS to support the growing fetus.
Compounds that interact with ESTROGEN RECEPTORS in target tissues to bring about the effects similar to those of ESTRADIOL. Estrogens stimulate the female reproductive organs, and the development of secondary female SEX CHARACTERISTICS. Estrogenic chemicals include natural, synthetic, steroidal, or non-steroidal compounds.
Cells lining the outside of the BLASTOCYST. After binding to the ENDOMETRIUM, trophoblasts develop into two distinct layers, an inner layer of mononuclear cytotrophoblasts and an outer layer of continuous multinuclear cytoplasm, the syncytiotrophoblasts, which form the early fetal-maternal interface (PLACENTA).
Cell surface proteins that bind oxytocin with high affinity and trigger intracellular changes which influence the behavior of cells. Oxytocin receptors in the uterus and the mammary glands mediate the hormone's stimulation of contraction and milk ejection. The presence of oxytocin and oxytocin receptors in neurons of the brain probably reflects an additional role as a neurotransmitter.
A genus of the subfamily CERCOPITHECINAE, family CERCOPITHECIDAE, consisting of five named species: PAPIO URSINUS (chacma baboon), PAPIO CYNOCEPHALUS (yellow baboon), PAPIO PAPIO (western baboon), PAPIO ANUBIS (or olive baboon), and PAPIO HAMADRYAS (hamadryas baboon). Members of the Papio genus inhabit open woodland, savannahs, grassland, and rocky hill country. Some authors consider MANDRILLUS a subgenus of Papio.

Dilatation and Curettage
A highly vascularized mammalian fetal-maternal organ and major site of transport of oxygen, nutrients, and fetal waste products. It includes a fetal portion (CHORIONIC VILLI) derived from TROPHOBLASTS and a maternal portion (DECIDUA) derived from the uterine ENDOMETRIUM. The placenta produces an array of steroid, protein and peptide hormones (PLACENTAL HORMONES).
Cells that line the inner and outer surfaces of the body by forming cellular layers (EPITHELIUM) or masses. Epithelial cells lining the SKIN; the MOUTH; the NOSE; and the ANAL CANAL derive from ectoderm; those lining the RESPIRATORY SYSTEM and the DIGESTIVE SYSTEM derive from endoderm; others (CARDIOVASCULAR SYSTEM and LYMPHATIC SYSTEM) derive from mesoderm. Epithelial cells can be classified mainly by cell shape and function into squamous, glandular and transitional epithelial cells.
Insulin-Like Growth Factor Binding Protein 1
One of the six homologous proteins that specifically bind insulin-like growth factors (SOMATOMEDINS) and modulate their mitogenic and metabolic actions. The function of this protein is not completely defined. However, several studies demonstrate that it inhibits IGF binding to cell surface receptors and thereby inhibits IGF-mediated mitogenic and cell metabolic actions. (Proc Soc Exp Biol Med 1993;204(1):4-29)
Gene Expression Regulation
A synthetic steroid with antigonadotropic and anti-estrogenic activities that acts as an anterior pituitary suppressant by inhibiting the pituitary output of gonadotropins. It possesses some androgenic properties. Danazol has been used in the treatment of endometriosis and some benign breast disorders.
A post-MORULA preimplantation mammalian embryo that develops from a 32-cell stage into a fluid-filled hollow ball of over a hundred cells. A blastocyst has two distinctive tissues. The outer layer of trophoblasts gives rise to extra-embryonic tissues. The inner cell mass gives rise to the embryonic disc and eventual embryo proper.

Methods of maintaining or growing biological materials in controlled laboratory conditions. These include the cultures of CELLS; TISSUES; organs; or embryo in vitro. Both animal and plant tissues may be cultured by a variety of methods. Cultures may derive from normal or abnormal tissues, and consist of a single cell type or mixed cell types.
The reproductive organ (GONADS) in female animals. In vertebrates, the ovary contains two functional parts: the OVARIAN FOLLICLE for the production of female germ cells (OOGENESIS); and the endocrine cells (GRANULOSA CELLS; THECA CELLS; and LUTEAL CELLS) for the production of ESTROGENS and PROGESTERONE.
Production of prostaglandin f2alpha and its metabolite by endometrium and yolk sac placenta in late gestation in the tammar wallaby, Macropus Eugenii. (1/3697)In this study, we investigated production of prostaglandin (PG) F2alpha and its metabolite, PGFM, by uterine tissues from tammar wallabies in late pregnancy. Endometrial explants were prepared from gravid and nongravid uteri of tammars between Day 18 of gestation (primitive streak) and Day 26.5 (term) and were incubated in Ham's F-10 medium supplemented with glutamine and antibiotics for 20 h. PGF2alpha and PGFM in the medium were assayed by specific, validated RIAs. Control tissues (leg muscle) did not produce detectable amounts of either PG. Both gravid and nongravid endometria secreted PGF2alpha, and production increased significantly in both gravid and nongravid uteri towards term. PGFM was produced in small amounts by both gravid and nongravid uteri, and the rate of production did not increase. Neither oxytocin nor dexamethasone stimulated PG production in vitro in any tissue at any stage. Thus, the surge in peripheral plasma PGFM levels seen at parturition may arise from increased uterine PG production, but further study is needed to define what triggers this release. (+info)
Expression of trophinin, tastin, and bystin by trophoblast and endometrial cells in human placenta. (2/3697)Trophinin, tastin, and bystin comprise a complex mediating a unique homophilic cell adhesion between trophoblast and endometrial epithelial cells at their respective apical cell surfaces. In this study, we prepared mouse monoclonal antibodies specific to each of these molecules. The expression of these molecules in the human placenta was examined immunohistochemically using the antibodies. In placenta from the 6th week of pregnancy, trophinin and bystin were found in the cytoplasm of the syncytiotrophoblast in the chorionic villi, and in endometrial decidual cells at the utero placental interface. Tastin was exclusively present on the apical side of the syncytiotrophoblast. Tissue sections were also examined by in situ hybridization using RNA probes specific to each of these molecules. This analysis showed that trophoblast and endometrial epithelial cells at the utero placental interface express trophinin, tastin, and bystin. In wk 10 placenta, trophinin and bystin were found in the intravillous cytotrophoblast, while tastin was not found in the villi. After wk 10, levels of all three proteins decreased and then disappeared from placental villi. (+info)
Down-regulation of oxytocin-induced cyclooxygenase-2 and prostaglandin F synthase expression by interferon-tau in bovine endometrial cells. (3/3697)Oxytocin (OT) is responsible for the episodic release of luteolytic prostaglandin (PG) F2alpha from the uterus in ruminants. The attenuation of OT-stimulated uterine PGF2alpha secretion by interferon-tau (IFN-tau) is essential for prevention of luteolysis during pregnancy in cows. To better understand the mechanisms involved, the effect of recombinant bovine IFN-tau (rbIFN-tau) on OT-induced PG production and cyclooxygenase-2 (COX-2) and PGF synthase (PGFS) expression in cultured endometrial epithelial cells was investigated. Cells were obtained from cows at Days 1-3 of the estrous cycle and cultured to confluence in RPMI medium supplemented with 5% steroid-free fetal calf serum. The cells were then incubated in the presence or absence of either 100 ng/ml OT or OT+100 ng/ml rbIFN-tau for 3, 6, 12, and 24 h. OT significantly increased PGF2alpha and PGE2 secretion at all time points (p < 0.01), while rbIFN-tau inhibited the OT-induced PG production and reduced OT receptor binding in a time-dependent manner. OT increased the steady-state level of COX-2 mRNA, measured by Northern blot, which was maximal at 3 h (9-fold increase) and then decreased with time (p < 0.01). OT also caused an increase in COX-2 protein, which peaked at 12 h (11-fold increase), as measured by Western blot. Addition of rbIFN-tau suppressed the induction of COX-2 mRNA (89%, p < 0.01) and COX-2 protein (50%, p < 0.01) by OT. OT also increased PGFS mRNA, and this stimulation was attenuated by rbIFN-tau (p < 0.01). To ensure that the decrease in COX-2 was not solely due to down-regulation of the OT receptor, cells were stimulated with a phorbol ester (phorbol 12-myristate 13-acetate; PMA) in the presence and absence of rbIFN-tau. The results showed that rbIFN-tau also decreased PMA-stimulated PG production and COX-2 protein. It can be concluded that rbIFN-tau inhibition of OT-stimulated PG production is due to down-regulation of OT receptor, COX-2, and PGFS. (+info)
Molecular and cellular aspects of endometrial receptivity. (4/3697)Endocrine and paracrine controls regulate the endometrium during the luteal phase of the cycle to permit implantation. Part of this differentiation process is the production of a specific secretion which fills the intrauterine cavity and glandular lumen. Its molecular composition originates from the gland secretion, from transudations from stroma, from the endometrial blood vessels, and last, but not least, from cellular components of apoptotic and exfoliated cells. We have studied the secretions of all phases during the menstrual cycle using patterns evaluated by SDS-PAGE, by laser densitometry or Western blots. Uterine secretion electrophoresis (USE) permits detailed analyses of the intrauterine micromilieu and allows clinical assessment of the receptive stage of endometrium during the luteal phase. Several individual protein bands have been defined as characteristic markers for such receptive pattern. We have isolated and identified the molecular structure of several of these proteins, e.g. histones, cyclophilin, transthyretin, haptoglobin and uteroglobin. Investigations on the endocrine regulation of these proteins, were carried out on the uterine secretions of patients treated with progesterone antagonists (mifepristone and onapristone). The results demonstrate how progesterone-dependent components produce a receptive pattern, which can serve as a useful and precise marker in the clinical diagnosis of the luteal phase. Essential progesterone-dependent components differentiating during the luteal phase may provide new targets for contraceptive interventions by preventing the physiological changes typical of receptivity.

Molecular control of the implantation window. (5/3697)Human endometrium is the end organ of the hypothalamic-pituitary-ovarian axis. Therefore, endometrium is susceptible to changes in the cases of infertility that originate from disturbances in the normal functioning of this axis. In addition, some cases of unexplained infertility may be due to altered endometrial function. This disturbed endometrial function may originate from lesions in the molecular repertoire that are crucial to implantation. Human endometrium becomes receptive to implantation by the blastocyst within a defined period during the menstrual cycle. The duration of this so-called 'endometrial receptivity' or 'implantation' period seems to span from few days after ovulation to several days prior to menstruation. Successful implantation results from a co-ordinated series of events that would allow establishment of a timely dialogue between a receptive endometrium and an intrusive blastocyst. The members of the molecular repertoire that make endometrium receptive to implantation are gradually being recognized. Among these are the cytokines, integrins, heat shock proteins, tastin and trophinin. In addition, the expression of a second set of genes including tumour necrosis factor alpha (TNF-alpha) and ebaf, may be the appropriate signal for the closure of the 'implantation window', for making the endometrium refractory to implantation and for preparing it for the menstrual shedding.

Marker genes of decidualization: activation of the decidual prolactin gene. (6/3697)Decidualization of human endometrial stromal (ES) cells in vitro is induced by cAMP analogues and ligands that elevate cellular cAMP levels in a manner resembling the gonadotrophins, prostaglandin E2 and relaxin (RLX). This differentiation process is marked by the onset of decidual prolactin (PRL) production in the late luteal phase of the cycle. Using transfection assays and a primary ES cell culture system, we have demonstrated that decidual PRL gene transcription is driven by an alternative upstream promoter (dPRL), approximately 6 kb upstream of the pituitary transcription start site. In primary cell cultures, RLX not only acutely but also permanently elevated cellular cAMP levels and induced PRL secretion after 6 days. Northern and Western blot analyses revealed all regulatory subunit isoforms (RIalpha, RIbeta, RIIalpha, RIIbeta) and catalytic subunits Calpha and Cbeta of protein kinase A (PKA) in ES cells. Transcript levels of PKA subunit isoforms are not altered during decidualization, but in decidualized ES cells exposed to elevated cellular cAMP levels by stimulation with RLX for >6 days, RIalpha protein levels were significantly reduced, whereas levels of all other forms remained unchanged. Reducing the availability of R subunits changed the R:C subunit ratio in favour of C and increased kinase activity. In transient transfections of undifferentiated ES cells, the dPRL promoter was activated by 8-Br-cAMP and by C subunit (Cbeta) of PKA. This induction, and the differentiation-dependent activity of the dPRL promoter in transfected decidualized cells, was effectively abolished by the co-expression of protein kinase inhibitor (PKI). A fragment of 332 bp of 5'-flanking region of the dPRL transcription start site was sufficient to mediate full inducibility by cAMP. cAMP activation of the dPRL promoter in ES cells was biphasic as an initial weak induction within 12 hours was followed by a subsequent, much more intense induction after 12 hours. The secondary induction was not seen with a control construct driven by a consensus cAMP response element (CRE) linked to a minimal promoter. The early response of the dPRL promoter depended upon a non-palindromic CRE at position -12 and mutation of this sequence led to omission of the early, but not of the delayed, induction. The major activation of the dPRL promoter depended upon a different region between position -332 and -270 since its deletion significantly reduced inducibility by cAMP. Its action was probably indirect as its kinetics differed from classic CRE-mediated responses, and it was specific to ES cells. (+info)
Changes in basement membrane thickness in the human endometrium during the luteal phase of the menstrual cycle. (7/3697)We have examined aspects of the fine structure of the basal laminae associated with the luminal and glandular epithelium and small blood vessels in the human endometrium. Four short studies are presented and reviewed. Study 1 examined biopsies from 20 fertile women taken on days after the luteinizing hormone surge (LH): LH +2, 4, 6, 8 and 10. The basal lamina (both lamina densa and lucida) increased in thickness over the period studied. Study 2 again studied the glandular epithelium and examined the effect of RU486 (a progesterone receptor blocker) administered on day LH +3 and biopsied on day LH +6. The basal laminae were found to be the same as LH +2 control group but thinner than LH +6 control. Study 3 documented increased thickness of the basal laminae between LH +6, 8 and 13 in the luminal epithelium. The within-group coefficient of variation was 16% and 27% for LH +6 and LH +13 groups but only 2 % for LH +8. Study 4 demonstrated an increase in basal lamina thickness associated with small blood vessels between LH +6 and LH +10 in normal fertile women. The basal lamina provides the interface between epithelial and mesenchymal environments; changes in its structure can alter the phenotypic expression of the epithelia. It is one of the maternal barriers that must be transgressed by the trophoblast during implantation. Together, these combined studies provide quantitative baseline structural information on the electron microscopical appearance of the basal lamina during the luteal phase of the menstrual cycle.

Endometrial microvascular growth in normal and dysfunctional states. (8/3697)As a tissue that exhibits rapid cyclical growth and shedding throughout the reproductive life of the female, human endometrium provides a good model for the study of normal physiological angiogenesis. The objective of this paper is to summarize recent data on endometrial vascular growth, present new data on regional variability in endothelial cell proliferation within the endometrium, and interpret this information in light of current knowledge of the mechanisms by which angiogenesis occurs. Conventional angiogenesis normally involves a series of steps which include endothelial cell activation, breakdown of the basement membrane, migration and proliferation of the endothelial cell, fusion of sprouts, and tube formation. Other mechanisms by which angiogenesis occurs include intussusception and vessel elongation. Using immunohistochemical techniques we have shown repeatedly that levels of endothelial cell proliferation within human endometrium do not show any consistent pattern across the different stages of the menstrual cycle, which is unexpected since significant vascular growth must occur during the proliferative phase, when the endometrium increases in thickness by up to 4-fold. There are two possible explanations for this; either there is no obligatory link between endometrial endothelial cell proliferation and new vessel formation, or there is significant variation in endothelial cell proliferation within different regions of the same uterus. Multiple samples from hysterectomy specimens subsequently demonstrated that the variability is due to real differences between individuals, as well as showing that the endothelial cell proliferation index is significantly elevated in functionalis compared with basalis. During these studies we observed that endothelial cell proliferation nearly always appeared inside existing endometrial vessels, rather than be associated with structures that could be identified as vascular sprouts. To explore further whether sprout formation occurs during endometrial angiogenesis, we investigated the immunohistochemical distribution of integrin alphavbeta3 on endometrial endothelial cells. As for endothelial cell proliferation, integrin alphavbeta3 immunostaining was seen only on endothelial cells that appeared within existing blood vessels. The results from these studies have major implications for our understanding of the mechanisms that control endometrial angiogenesis. The lack of correlation between menstrual cycle stage and endothelial cell proliferation index, or endothelial cell expression of integrin alphavbeta3, suggests that vascular growth is not under the overall control of oestrogen and progesterone.

AU - Iizuka, R.. AU - Hirano, H.. PY - 1989/5/1. Y1 - 1989/5/1. N2 - Lectin binding patterns in normal human endometrium were examined by light and electron microscopy using seven different lectins (ConA, WGA, RCA, PNA, UEA-1, DBA, and SBA). For light microscopic observations, criteria based on the incidence and intensity of cells positive for the lectin staining were adopted to evaluate the different staining patterns of the proliferative and secretory endometria obtained by the avidin-biotin-peroxidase complex (ABC) technique. At the light microscopic level, ConA, WGA, and RCA stained endometrial glandular cells in both phases. The number of PNA-positive cells with the binding sites entirely limited to the apical surface tended to be reduced slightly in the secretory phase. UEA-1 weakly stained the ...
Effects of bisphenol A on human endometrial endothelial cell angiogenic activity in vitro
Evidence from an abundant number of studies suggests that human female reproductive functions have become impaired over the past half century and that there might be a relationship between endocrine disrupting chemicals (EDCs) and reduced fertility. It is, however, not known by what mechanisms EDCs affect different reproductive functions such as endometrial receptivity, embryo implantation and placentation.. The endometrium is continuously changing its morphological and functional properties, responding to cyclic changes of oestrogen and progesterone levels during the menstrual cycle. These changes include monthly preparation for embryo implantation through changed endometrial angiogenic activity and consequent changes in endometrial vasculature.. Use of primary human endometrial endothelial cells (HEECs) in this work was evaluated as a possible screening tool for effects caused by EDCs on human endometrial vasculature and subsequently on various endometrial functions.. In this study HEEC and ...
The Endometrial Cycle - Menstrual Cycle - Flanders Health Blog
The cyclic production of estrogen and progesterone during the ovarian cycle induces a corresponding cycle of endometrial proliferation and development. (Fig. 1, bottom panel). This endometrial cycle includes a proliferative phase lasting about 11 days, a secretory phase lasting about 12 days, and a desquamative or menstrual phase of about five days during which menstruation ensues.. During the follicular phase of the ovarian cycle, the endometrium proliferates and increases in thickness under the influence of estradiol. This marks the proliferative phase of the endometrial cycle. During the luteal phase of the ovarian cycle, progesterone stimulates further endometrial cell proliferation, differentiation, and secretory development to support implantation and to nourish the developing conceptus. This is the secretory phase of the endometrial cycle. Progesterone also promotes secretory changes in the lining of the fallopian tubes that will support the fertilized egg as it travels down the fallopian ...
Transvaginal endometrial perfusion of granulocyte colony-stimulating factor for infertile women with thin endometrium in frozen...
Introduction: We often see patients with a thin endometrium in ART cycles, in spite of standard and adjuvant treatments. Improving endometrial growth in patients with a thin endometrium is very difficult. Without adequate endometrial thickness these patients, likely, would not have reached embryo transfer. Materials and Methods: This is a non randomized intervential clinical trial. Among 68 infertile patients with thin endometrium (7 mm) at the 12th-13th cycle day, 34 patients received G-CSF (300 microgram/lmL) to improve endometrial thickness. It was directly administered by slow intrauterine infusion using IUI catheter. If the endometrium had not reached at least a 7-mm within 48-72 h, a second infusion was given. Endometrial thickness was assessed by serial vaginal ultrasound at the most expanded area of the endometrial stripe. The cycle was cancelled in the patients with thin endometrium (endometrial thickness 7mm) until 19th cycle day ultimately. Results: The cycle cancelation rate owing to ...

Effects of progesterone administered by nasal spray on the human postmenopausal endometrium | IRIS Univ. Bari
The aim of the study was to assess the effectiveness of progesterone (P) administered by nasal spray (NS) in inducing secretory changes within estrogen and non-estrogen primed postmenopausal endometrium. Ten healthy post-menopausal women before vaginal hysterectomy for prolapse were randomly treated by either oral estrogens for 3-4 weeks combined for the last 5-7 days with nasally administered P at the daily dose of 34 mg, or by only P for 6 days. Endometrial samples were taken before P administration and 8 h after the last dose. In the group not treated with estrogens, P did not induce significant secretory changes in any case except one which showed a proliferative endometrial pattern at the first evaluation. In the group treated with estrogens, in all the cases after P administration clear secretory changes (abundant vacuoles, endoluminal secretion) occurred. It is possible to conclude that P administered by NS exerts an end-organ effect within the endometrium of postmenopausal women ...

Inhibition of Histone Deacetylase Activity in Human Endometrial Stromal Cells Promotes Extracellular Matrix Remodelling and...
Invasion of the trophoblast into the maternal decidua is regulated by both the trophoectoderm and the endometrial stroma, and entails the action of tissue remodeling enzymes. Trophoblast invasion requires the action of metalloproteinases (MMPs) to degrade extracellular matrix (ECM) proteins and in turn, decidual cells express tissue inhibitors of MMPs (TIMPs). The balance between these promoting and restraining factors is a key event for the successful outcome of pregnancy. Gene expression is post-transcriptionally regulated by histone deacetylases (HDACs) that unpacks condensed chromatin activating gene expression. In this study we analyze the effect of histone acetylation on the expression of tissue remodeling enzymes and activity of human endometrial stromal cells (hESCs) related to trophoblast invasion control. Treatment of hESCs with the HDAC inhibitor trichostatin A (TSA) increased the expression of TIMP-1 and TIMP-3 while decreased MMP-2, MMP-9 and uPA and have an inhibitory effect on trophoblast
A Two-Cohort RNA-seq Study Reveals Changes in Endometrial and Blood miRNome in Fertile and Infertile Women
The endometrium undergoes extensive changes to prepare for embryo implantation and microRNAs (miRNAs) have been described as playing a significant role in the regulation of endometrial receptivity. However, there is no consensus about the miRNAs involved in mid-secretory endometrial functions. We analysed the complete endometrial miRNome from early secretory (pre-receptive) and mid-secretory (receptive) phases from fertile women and from patients with recurrent implantation failure (RIF) to reveal differentially expressed (DE) miRNAs in the mid-secretory endometrium. Furthermore, we investigated whether the overall changes during early to mid-secretory phase transition and with RIF condition could be reflected in blood miRNA profiles. In total, 116 endometrial and 114 matched blood samples collected from two different population cohorts were subjected to small RNA sequencing. Among fertile women, 91 DE miRNAs were identified in the mid-secretory vs. early secretory endometrium, while no ...

The mouse endometrium contains epithelial, endothelial and leucocyte populations expressing the stem cell marker telomerase...
STUDY HYPOTHESIS: The mouse endometrium harbours stem/progenitor cells that express the stem cell marker mouse telomerase reverse transcriptase (mTert). STUDY FINDING: We used a mouse carrying a transgenic reporter for mTert promoter activity to identify rare endometrial populations of epithelial and endothelial cells that express mTert. WHAT IS KNOWN ALREADY: Stem/progenitor cells are hypothesized to be responsible for the remarkable regenerative capacity of the endometrium, but the lack of convenient endometrial stem/progenitor markers in the mouse has hampered investigations into the identity of these cells. STUDY DESIGN, SAMPLES/MATERIALS, METHODS: A mouse containing a green fluorescent protein (GFP) reporter under the control of the telomerase reverse transcriptase promoter (mTert-GFP) was used to identify potential stem/progenitor cells in the endometrium. mTert promoter activity was determined using fluorescence microscopy and flow cytometry to identify GFP(+) cells. GFP(+) cells were examined

METHODS: In situ hybridization and immunohistochemistry were applied to determine mRNA and protein. RESULTS: After mifepriston injection, the number of implantation sites were obviously reduced, mifepriston could inhibit the embryo implantation in mouse. The expression of apoptosis related genes, Fas and FasL, in mouse endometrium was also decreased after mifepriston treatment. CONCLUSION: The expression of apoptosis related genes Fas and FasL is regulated by mifepriston and the inhibitory effect of mifepriston on the embryo implantation may be mediated by action on the Fas/FasL system.. AB - AIM: To investigate the anti-implantation mechanism of mifepriston. METHODS: In situ hybridization and ...
British Library EThOS: Characterization of the endometrium of women with reproductive failure
Differentiation of human endometrial stromal cells (HESCs) into decidual cells represents a highly coordinated process essential for embryo implantation. Following the post-ovulatory rise in progesterone levels HESCs undergo biochemical and morphological transformation in a process known as decidualization. It heralds the end of the mid-secretory phase implantation window, defined as the limited period during which progesterone-driven changes in the luminal epithelium allow apposition, attachment and invasion of a developmentally competent blastocyst. Failure of the endometrium to acquire a receptive phenotype is widely viewed as a major cause of infertility and IVF treatment failure. Conversely, recurrent pregnancy loss (RPL) is associated with impaired decidualization. Firstly, analysis of mid-secretory endometrial biopsies from RPL patients demonstrated that there is a decreased expression of the decidual marker, Prolactin but increased levels of pro-inflammatory cytokine, Prokineticin-1. ...
Hormonal Effects on the Uterus and Endometrium - Full Text View - ClinicalTrials.gov
Estrogen and progesterone induce characteristic and predictable morphological changes in the endometrium that are required for successful implantation and pregnancy. The mechanism(s) by which estrogen and progesterone exert these effects on the endometrium is not known. This is a tissue collection protocol to obtain endometrium and/or menstrual effluent from normally cycling women, women with endometriosis and women with infertility.. This tissue will be used for future studies intended to understand gonadal steroid action on the endometrium We propose to identify peptides that are induced by endogenous estrogen and progesterone using in situ hybridization, immunohistochemistry, microarray analysis and/or culture of human endometrium obtained at hormonally different times of the cycle. Regularly cycling women not at risk for pregnancy will be studied for two menstrual cycles. The first, pre-biopsy cycle, will be characterized by daily basal body temperature measurements and a luteal phase ...
Contribution of Bone Marrow-Derived Stem Cells to Endometrium and Endometriosis - Du - 2007 - STEM CELLS - Wiley Online Library
Here, we demonstrate that bone marrow-derived stem cells engraft the murine endometrium. Both stromal and epithelial cells were derived from bone marrow origin. These data show the potential for stem cells to have a role in the regeneration or repair of this tissue after injury. However, the small number of engrafted cells limits their potential to significantly contribute to cyclic endometrial function during each estrus cycle. In other organs, the homing and engraftment of stem cells are influenced by injury and inflammation, presumably through the generation of a signal emanating from the damaged tissue [17, -19]. A more significant engraftment of endometrium by bone marrow is likely to occur after endometrial injury or inflammatory insult. Additionally, the proliferation and development of endometrium are entirely regulated by hormonal stimuli. Ovarian estrogen and progesterone drive endometrial growth and apoptosis [20, 21]. As the radiation used prior to bone marrow transplantation ...
The mutational landscape of normal human endometrial epithelium | Nature
All normal somatic cells are thought to acquire mutations, but understanding of the rates, patterns, causes and consequences of somatic mutations in normal cells is limited. The uterine endometrium adopts multiple physiological states over a lifetime and is lined by a gland-forming epithelium1,2. Here, using whole-genome sequencing, we show that normal human endometrial glands are clonal cell populations with total mutation burdens that increase at about 29 base substitutions per year and that are many-fold lower than those of endometrial cancers. Normal endometrial glands frequently carry driver mutations in cancer genes, the burden of which increases with age and decreases with parity. Cell clones with drivers often originate during the first decades of life and subsequently progressively colonize the epithelial lining of the endometrium. Our results show that mutational landscapes differ markedly between normal tissues-perhaps shaped by differences in their structure and physiology-and indicate

PY - 1999. Y1 - 1999. N2 - Blastocyst implantation in the baboon usually occurs between 8 and 10 days post ovulation. Changes that occur within this window of receptivity and immediately following implantation can be divided into three distinct phases. The first phase, regulated by estrogen and progesterone, is characterized primarily by changes in both the luminal and glandular epithelial cells in preparation for blastocyst apposition and attachment. The second phase is the further modulation of these steroid induced changes in both epithelial and stromal cells by embryonic signals. The final phase is associated with trophoblast invasion and the remodeling of the endometrial stromal compartment. During the initial phase, the actions of estrogen and progesterone are dependent on the presence of specific ...

Endometrium - Wikipedia
Endometrium adalah lapisan terdalam pada rahim dan tempatnya menempelnya ovum yang telah dibuahi. Diperlukan waktu sekitar 4-5 hari setelah pembuahan. Di dalam lapisan Endometrium terdapat pembuluh darah yang berguna untuk menyalurkan zat makanan ke lapisan ini. pembuluh darah ini akan luruh dan menyebabkan terjadinya menstruasi pada wanita apabila tidak terjadi pembuahan ovum oleh sel sperma. Saat ovum yang telah dibuahi (yang biasa disebut fertilisasi) menempel di lapisan endometrium (implantasi), maka ovum akan terhubung dengan badan induk dengan plasenta yang berhubung dengan tali pusat pada bayi. Pada suatu fase di mana ovum tidak dibuahi oleh sperma, maka kurpus luteum akan berhenti memproduksi hormon progesteron dan berubah menjadi korpus albikan yang menghasilkan sedikit hormon diikuti meluruhnya lapisan endometrium yang telah menebal, karena hormon estrogen dan progesteron telah berhenti diproduksi. Pada fase ini, biasa disebut menstruasi atau peluruhan dinding rahim. ...
Endometrial stromal cells: isolation, expansion, morphological and functional properties | Experimental oncology
Aim: We aimed to study biological properties of human endometrial stromal cells in vitro. Materials and Methods: The endometrium samples (n = 5) were obtained
A receptive endometrium and viable blastocyst are the two necessary conditions of successful implantation. The endometrium is receptive only during the window of implantation, which lasts approximately four days (day 20-23), and occurs in humans during the mid-secretory phase in a normal 28-day menstrual cycle. With some disparity between sources, it has been stated to occur from 7 days after ovulation until 9 days after ovulation, or days 6-10 postovulation. On average, it occurs during the 20th to the 23rd day after the last menstrual period. During the window of implantation, the endometrium undergoes extensive morphological and physiological changes to facilitate implantation of the embryo, including becoming more vascular and edematous with the glands displaying enhanced secretory activity. This process is precisely regulated. Among all the regulating elements, reproductive hormones are the leading factors. These changes are collectively known as the plasma membrane transformation and bring ...

Isolation of viruses from cultures of bovine endometrial cells. - Immunology
Endometrial cells from the uteri of pregnant and nonpregnant cattle were cultured. The presence of one or both of two viruses, noncytopathic mucosal disease virus and bovine syncytial virus, was demonstrated in seven of 19 endometria investigated. It was necessary to subculture the cells an average of four times to detect the viral infections. Difficulties were encountered in producing endometrial cell cultures from cows at term or near the end of term and also from older animals. The infections detected may be significant because both of the viruses isolated are capable of infecting the bovine fetus in utero and mucosal disease virus has been associated with bovine fetal diseases.
Dr.Malpanis Blog: July 2009
However if the lining remains thin in spite of high doses of estrogen, this means the problem is either one of poor blood supply ; or a damaged endometrium. Some doctors have used color Doppler ultrasound to measure uterine blood flow, but the results with this have been mixed. Others have tried using vaginal viagra to try to improve endometrial blood flow. Since there is no reliable method to assess uterine blood flow , the next step is to determine whether the endometrium has been damaged or not. There are two possible causes of end-organ damage when the endometrium is nonresponsive. One is that the endometrium has been anatomically distorted because of intrauterine adhesions ( a common cause for this in India is uterine tuberculosis. This condition is called Ashermann syndrome; and this can be diagnosed either with a hysterosalpingogram , which shows filling defects within the uterine cavity ; or with hysteroscopy , during which procedure the scars can be surgically removed. However in some ...

Conceptus elongation in ruminants: roles of progesterone, prostaglandin, interferon tau and cortisol | Journal of Animal...
Results of recent studies in sheep support the concept that PGs regulate expression of elongation- and implantation-related genes in the endometrial epithelia of ruminants during early pregnancy and are involved in conceptus elongation [46, 60, 98] (Figures 1 and 2). The conceptus and endometria synthesize a variety of PGs during early pregnancy in both sheep and cattle [99-104]. The endometrium produces and uterine lumen contains substantially more PGs during early pregnancy than during the estrous cycle [105-107]. The dominant cyclooxygenase expressed in both the endometrium and trophectoderm of the elongating conceptus is PTGS2 [104-106]. Although the antiluteolytic effects of IFNT are to inhibit expression of the OXTR in the endometrial LE and sGE of early pregnant ewes, it does not impede up-regulation of PTGS2, a rate-limiting enzyme in PG synthesis [102, 107]. In sheep, PTGS2 activity in the endometrium is stimulated by IFNT, and PTGS2-derived PG were found to mediate, in part, the ...

To study the effect of endometrial thickness and pattern measured using ultrasound upon pregnancy outcomes in patients undergoing IVF-ET. One thousand nine hundred thirty-three women undergoing IVF treatment participated in the study. We assessed and recorded endometrial patterns and thickness on the day of human chorionic gonadotropin (hCG) administration. Receiver operator curves (ROC) were used to determine the predictive accuracy of endometrial thickness. Cycles were divided into 3 groups depending on the thickness (group 1: ≤ 7 mm; group 2: | 7 mm to ≤ 14 mm; group 3: | 14 mm). Each group was subdivided into three groups according to the endometrial pattern as follows: pattern A (a triple-line pattern consisting of a central hyperechoic line surround by two hypoechoic layers); pattern B (an intermediate isoechogenic pattern with the same reflectivity as the surrounding myometrium and a poorly defined central echogenic line); and pattern C (homogenous, hyperechogenic endometrium).

Introduction: Unscheduled breakthrough-bleeding (spotting) is a common problem in progestin only contraceptive (POC) users. A major feature of POC-endometria is the presence of fragile luminal epithelium (LE), susceptible to shedding/bleeding. We propose that disturbances in Wnt signalling, mediated by signals from the decidualized stroma in POC-endometria, cause LE alterations underlying fragility and bleeding events. Materials & methods: Wnt5a and 7a, β-catenin, E-cadherin and DKK1 were examined by immunohistochemistry in POC- and normal endometrium. Primary human endometrial stromal cells (HESC) were treated with estrogen (10-8M) and progesterone (MPA, 10-7M), both prolactin (PRL) and DKK1 were assessed by ELISA in decidualized (DEC, day 12) versus non-DEC (day 2) media. β-catenin, phospho(P)-β-catenin, APC and Wnt7a localization was examined by immunocytochemistry in recombinant human (rh)-DKK1 treated endometrial epithelial cells (EEC) and P-β-catenin abundance was determined by ...

Detection of Intraepithelial and Stromal Langerin and CCR5 Positive Cells in the Human Endometrium : Potential Targets for HIV...
Both the upper (endocervix and uterus) and lower (ectocervix and vagina) female genital tract mucosa are considered to be target sites for sexual transmission of HIV. There are a few reports on the T cell and antigen-presenting cell distribution in human endometrial tissue however, there is little known about the expression of the HIV co-receptor CCR5 and HIV-binding C-type lectin receptors on endometrial cell subsets. We therefore assessed endometrial tissue sections from HIV seronegative women undergoing hysterectomy of a benign and non-inflammatory cause for phenotypic characterization of potential HIV target cells and receptors by immunohistochemistry. Langerin was expressed on intraepithelial CD1a+CD4+ and CD11c+CD4+ Langerhans cells. Furthermore, CCR5+CD4+CD3+ T cells, DC-SIGN+MR+CD11c+ myeloid dendritic cells and MR+CD68+ macrophages were found within or adjacent to the epithelium of the uterine lumen. In addition, occasional CD123+BDCA-2+ plasmacytoid dendritic cells were detected deep ...

Sweet Pea - My TTC Journey: Endometrial Biopsy Results
Dr. Carolyn Givens for InfertilityDoctor.com, tells us that one protein produced by the endometrium during the implantation window that has some evidence for a scientific basis for a role in implantation is the cell-to-cell adhesion molecule known as beta-3 integrin. Integrins are a class of cell surface proteins that appear to act in all types of cell-to-cell recognition and adhesion processes. The beta-3 class of these proteins has been shown to be produced in response to progesterone in the endometrium and are purported to be one of the key proteins for adhesion of embryos to the endometrium. Failure to express this protein appropriately has been theorized to be a cause of unexplained implantation failure(1). To simplify, beta-3 integrin is the glue that binds the embryo to the uterine wall for successful implantation in the endometrium (uterine lining). Without this glue, the embryo will not attach properly and could result in miscarriages. ...

To determine whether pregnant-specific substances are produced in the bovine corpus luteum (CL), this study evaluated the differences of gene and protein expressions between in the pregnant and in nonpregnant CL. Physiological roles of cytokines and steroids in the bovine CL and endometrial functions are also investigated. As a result, gene expressions of several substances such as prostaglandin receptors or tumor necrosis factor (TNF) are more abundant in the pregnant CL. Moreover, cellular localization of TNF and progesterone receptors in the bovine CL and endometrium are clarified in the present study. Thus, the present study provides a new concept in regulating CL and endometrial function in cows. ...

Altered endometrial immune gene expression in beef heifers with retarded embryos
The aim of the present study was to compare endometrial gene expression profiles in a group of beef heifers yielding viable or retarded embryos on Day 7 after oestrus as a means of potentially explaining differences in embryo survival rates. Heifers were classified as either: (1) viable, when the embryo collected on Day 7 after oestrus was at the correct developmental stage (i.e. morula/early blastocyst); or (2) retarded, when the embryo was arrested at the 2-16-cell stage. The focus of the present study was on genes that were associated with either the pro- or anti-inflammatory immune response. Endometrial gene expression was determined using quantitative real-time polymerase chain reaction analysis. Expression of the β-defensin (DEFB1), interferon (IFN)-α (IFNA), IFN-γ (IFNG), interleukin (IL)-6 (IL6), IL-10 (IL10), forkhead box P3 (FOXP3) and natural cytotoxicity triggering receptor 1 (NCR1) genes was lower in endometria from viable than retarded heifers.

Newly Invented Endometrial Function Test (EFT®) Solves the Puzzle of Unexplained Infertility
The endometrium is made up of stroma and glands. The endometrial stroma is the tissue that supports the glands and holds the endometrium together, much like the cake supports the fruit in a fruitcake. Fertile women expressed cyclin E in their glands up to about cycle day 19, and then did not have any after that, said Kliman. Infertile women, on the other hand, much more frequently expressed cyclin E well after cycle day 19, often to the end of their cycles. The stroma in both groups was the same. These results suggest that infertile women have a defect in the way the stroma communicates with glands ...

Leptin (Lep) is known for its involvement in the regulation of reproductive functions. It is important for uterine receptivity, implantation, placental growth and maternal energy homeostasis in several species, but Leps function in the pregnant dog has not been investigated. Pregnant bitches were ovariohysterectomized at pre-implantation, post-implantation, mid-gestation and prepartum luteolysis. Two additional groups were treated with aglepristone in mid-gestation, and ovariohysterectomized 24 or 72 h later. Lep and leptin receptor (LepR) gene expression was detected by semi-quantitative real-time PCR in pre-implantation and inter-placental uterine sections (Ut) and in utero-placental compartments (Ut/Pl). Immunohistochemistry and in situ hybridization (ISH) were performed for Lep and LepR protein and mRNA localization. Parametric one-way ANOVA, paired t-test and Wilcoxon signed-rank test were used for statistical analysis. In the Ut/Pl, Lep expression was higher at post-implantation and prepartum
