Int J Mol Sci 2023; 24:ijms24032453.

Abstract
The molecular pathogenesis of endometriosis has been associated with pathological alterations of protein expression via disturbances in homeostatic genes, miRNA expression profiles, and signaling pathways that play an essential role in the epithelial-mesenchymal transition (EMT) process. TGF-β1 has been hypothesized to play a key role in the development and progression of endometriosis, but the activation of a specific mechanism via the TGF-β-SMAD-ILK axis in the formation of endometriotic lesions is poorly understood. The aim of this study was to assess the expression of EMT markers (TGF-β1, SMAD3, ILK) and miR-21 in ectopic endometrium (ECE), in its eutopic (EUE) counterpart, and in the endometrium of healthy women. The expression level of the tested genes and miRNA was also evaluated in peripheral blood mononuclear cells (PBMC) in women with and without endometriosis. Fifty-four patients (n = 54; with endometriosis, n = 29, and without endometriosis, n = 25) were enrolled in the study. The expression levels (RQ) of the studied genes and miRNA were evaluated using qPCR. Endometriosis patients manifested higher TGF-β1, SMAD3, and ILK expression levels in the eutopic endometrium and a decreased expression level in the ectopic lesions in relation to control tissue. Compared to the endometrium of healthy participants, miR-21 expression levels did not change in the eutopic endometrium of women with endometriosis, but the RQ was higher in their endometrial implants. In PBMC, negative correlations were found between the expression level of miR-21 and the studied genes, with the strongest statistically significant correlation observed between miR-21 and TGF-β1. Our results suggest the loss of the endometrial epithelial phenotype defined by the differential expression of the TGF-β1, SMAD3 and ILK genes in the eutopic and ectopic endometrium. We concluded that the TGF-β1-SMAD3-ILK signaling pathway, probably via a mechanism related to the EMT, may be important in the pathogenesis of endometriosis. We also identified miR-21 as a possible inhibitor of this TGF-β1-SMAD3-ILK axis.

Abstract
Human endometrial and decidual stromal cells are the same cells in different environments (non-pregnancy and pregnancy, respectively). Although some authors consider decidual stromal cells to arise solely from the differentiation of endometrial stromal cells, this is a debatable issue given that decidualization processes do not end with the formation of the decidua, as shown by the presence of stromal cells from both the endometrium and decidua in both undifferentiated (non-decidualized) and decidualized states. Furthermore, recent functional and transcriptomic results have shown that there are differences in the decidualization process of endometrial and decidual stromal cells, with the latter having a greater decidualization capacity than the former. These differences suggest that in the terminology and study of their characteristics, endometrial and decidual stromal cells should be clearly distinguished, as should their undifferentiated or decidualized status. There is, however, considerable confusion in the designation and identification of uterine stromal cells. This confusion may impede a judicious understanding of the functional processes in normal and pathological situations. In the present article we analyse the different terms used in the literature for different types of uterine stromal cells, and propose that a combination of differentiation status (undifferentiated, decidualized) and localization (endometrium, decidua) criteria should be used to arrive at a set of accurate, unambiguous terms. The cell identity of uterine stromal cells is also a debatable issue: phenotypic, functional and transcriptomic studies in recent decades have related these cells to different established cells. We discuss the relevance of these associations in normal and pathological situations.

Abstract
Aim: Nowadays, infertility problems affect a high percentage of couples. This study aimed to evaluate the effect of plasma rich in growth factors (PRGF-Endoret, hereafter PRGF) as a promising coadjuvant therapy in assisted reproductive techniques and its possible role in implantation and pregnancy rates. This retrospective study included 36 PRGF cycles in 27 women with one of the following reproductive disorders: recurrent implantation failure (n = 16), repeated abortion (n = 8), and thin endometrium (n = 3). Methods: PRGF was obtained from each patient and administered as three consecutive intrauterine instillations. The endometrial thickness was measured after each PRGF infusion and a good-quality embryo transfer was performed for every patient. Endometrial thickness, biochemical pregnancy, and miscarriage rate were the primary measured outcomes. Results: PRGF increased the endometrial growth respecting the initial thickness in all cases. The biochemical pregnancy rate determined as positive beta-human chorionic gonadotropin (β-hCG) was 59%, considering the total number of patients; the ongoing pregnancy percentage was 48%. PRGF application day was relevant with a significant probability of achieving pregnancy (p < 0.01) when the first PRGF infusion was carried out beyond 6.5 days after the first day of the woman's cycle and the second one beyond 9.5 days of the menstrual cycle. Conclusions: Intrauterine autologous PRGF infusion is a safe, easily accessible, and inexpensive therapy that could collaborate in fertility treatments by optimizing the endometrium for implantation and thus favoring the crosstalk between the embryo and the uterus improving the embryo-maternal dialogue.

Abstract
The maladies affecting the female reproductive tract (FRT) range from infections to endometriosis to carcinomas. In vitro models of the FRT play an increasingly important role in both basic and translational research, since the anatomy and physiology of the FRT of humans and other primates differ significantly from most of the commonly used animal models, including rodents. Using organoid culture to study the FRT has overcome the longstanding hurdle of maintaining epithelial phenotype in culture. Both ECM-derived and engineered materials have proved critical for maintaining a physiological phenotype of FRT cells in vitro by providing the requisite 3D environment, ligands, and architecture. Advanced materials have also enabled the systematic study of factors contributing to the invasive metastatic processes. Meanwhile, microphysiological devices make it possible to incorporate physical signals such as flow and cyclic exposure to hormones. Going forward, advanced materials compatible with hormones and optimised to support FRT-derived cells' long-term growth, will play a key role in addressing the diverse array of FRT pathologies and lead to impactful new treatments that support the improvement of women's health. STATEMENT OF SIGNIFICANCE: The female reproductive system is a crucial component of the female anatomy. In addition to enabling reproduction, it has wide ranging influence on tissues throughout the body via endocrine signalling. This intrinsic role in regulating normal female biology makes it susceptible to a variety of female-specific diseases. However, the complexity and human-specific features of the reproductive system make it challenging to study. This has spurred the development of human-relevant in vitro models for helping to decipher the complex issues that can affect the reproductive system, including endometriosis, infection, and cancer. In this Review, we cover the current state of in vitro models for studying the female reproductive system, and the key role biomaterials play in enabling their development.

Abstract
Endometrial function is essential for embryo implantation and pregnancy, but managing endometrial thickness that is too thin to support pregnancy or an endometrium of compromised functionality due to intrauterine adhesions is an ongoing challenge in reproductive medicine. Here, we review current and emerging therapeutic and experimental options for endometrial regeneration with a focus on animal models used to study solutions for Asherman's syndrome and endometrial atrophy, which both involve a damaged endometrium. A review of existing literature was performed that confirmed the lack of consensus on endometrial therapeutic options, though promising new alternatives have emerged in recent years (platelet-rich plasma, exosomes derived from stem cells, bioengineering-based techniques, endometrial organoids, among others). In the future, basic research using established experimental models of endometrial pathologies (combined with new high-tech solutions) and human clinical trials with large population sizes are needed to evaluate these emerging and new endometrial therapies.

Abstract
It is suggested that aberrantly expressed microRNAs are involved in the pathogenesis of endometriosis. Our previous study demonstrated that expression of the microRNA hsa-miR-199a-3p is attenuated in human endometriotic cyst stromal cells (ECSCs). The current study aimed to define the roles of hsa-miR-199a-3p in the development of endometriosis. ECSCs and normal endometrial stromal cells (NESCs) were isolated from ovarian endometrioma and normal endometrial tissues, respectively. We evaluated the effect of transfected hsa-miR-199a-3p on the migration, invasion, and contractility of ECSCs using Transwell migration assays, in vitro wound healing assays, Transwell invasion assays, and collagen gel contraction assays. We also examined the downstream target of hsa-miR-199a-3p with an online public database search and luciferase reporter assay. Expression of hsa-miR-199a-3p in ECSCs was significantly lower than that in NESCs, whereas the expression of p21-activated kinase 4 (PAK4) mRNA was significantly higher. Transfection of hsa-miR-199a-3p inhibited the migration, invasion, and contractility of ECSCs via inhibition of PAK4 mRNA expression. PAK4 was confirmed to be the direct target of hsa-miR-199a-3p. Transfection of PAK4 small interfering RNA and the PAK4 inhibitor PF-3758309 also inhibited ECSC migration, invasion, and contractility. These findings suggest that hsa-miR-199a-3p may act as a tumor suppressor in endometriosis development. Attenuation of hsa-miR-199a-3p expression was favorable for ECSCs to acquire the highly invasive, motile, and contractile characteristics of endometriotic cells and is involved in the development of endometriosis. Accordingly, PAK4 inhibitors may be promising for the treatment of endometriosis.

Scar-Free Healing of Endometrium: Tissue-Specific Program of Stromal Cells and Its Induction by Soluble Factors Produced After Damage. Front Cell Dev Biol 2021; 9:616893.

Abstract
Besides certain exceptions, healing of most tissues in the human body occurs via formation of scar tissue, rather than restoration of lost structures. After extensive acute injuries, this phenomenon substantially limits the possibility of lost function recovery and, in case of chronic injury, it leads to pathological remodeling of organs affected. Managing outcomes of damaged tissue repair is one of the main objectives of regenerative medicine. The first priority for reaching it is comparative investigation of mechanisms responsible for complete restoration of damaged tissues and mechanisms of scarring. However, human body tissues that undergo complete scar-free healing are scarce. The endometrium is a unique mucous membrane in the human body that heals without scarring after various injuries, as well as during each menstrual cycle (i.e., up to 400 times during a woman's life). We hypothesized that absence of scarring during endometrial healing may be associated with tissue-specific features of its stromal cells (SCs) or their microenvironment, since SCs transform into myofibroblasts-the main effector link of scarring. We found that during healing of the endometrium, soluble factors are formed that inhibit the transition of SCs into myofibroblasts. Without influence of these factors, the SCs of the endometrium undergo transformation into myofibroblasts after transforming growth factor β1 (TGF-β1) treatment as well as the SCs from tissues that heal by scarring-skin or fat. However, unlike the latter, endometrial SCs organize extracellular matrix (ECM) in a specific way and are not prone to formation of bulky connective tissue structures. Thus, we may suggest that tissue-specific features of endometrial SCs along with effects of soluble factors secreted in utero during menstruation ensure scar-free healing of human endometrium.

Abstract
STUDY QUESTION Can menstrual stem cells (MenSCs) inhibit myofibroblast differentiation and reverse transforming growth factor β (TGFβ)-mediated activation of myofibroblast phenotypes in human endometrial stromal cells (ESCs)? SUMMARY ANSWER MenSCs suppressed endometrial myofibroblast differentiation and reversed TGFβ-mediated activation of myofibroblast phenotypes, which might be associated with activation of the Hippo/TAZ pathway. WHAT IS KNOWN ALREADY The potential effect of MenSCs as a cell therapy include attenuation of intrauterine adhesions, but the underlying mechanisms by which MenSCs exerts these effects are not entirely understood. STUDY DESIGN, SIZE, DURATION We evaluated the antagonistic effects of MenSCs on myofibroblast differentiation as well as the broader effect of the Hippo/TAZ signaling pathway on TGFβ-mediated induction of myofibroblast gene expression. The study design was based on a cohort of clinical proliferative phase endometrial samples obtained from three healthy premenopausal females with regular menstrual cycles. PARTICIPANTS/MATERIALS, SETTING, METHODS ESCs were cocultured with MenSCs or in MenSC-conditioned medium. Fibrotic markers (αSMA, collagen I, CTGF and fibronectin) as well as proliferation and wound-healing abilities were evaluated. Components of the Hippo/TAZ pathway (TAZ, p-TAZ, MOB1, p-MOB1, LATS1 and p-LATS1) were also investigated. Cell Counting Kit 8, wound healing assay, real-time PCR, western blotting, immunofluorescence and shRNA knockdown approaches were used to validate the findings. MAIN RESULTS AND THE ROLE OF CHANCE MenSCs inhibited myofibroblast activation, resulting in more rapid proliferation of ESCs. MenSCs downregulated the expression of myofibroblast markers αSMA and collagen I and promoted endometrial wound healing. Coculture with MenSCs also attenuated the TGFβ-mediated increase in expression of fibrotic marker genes αSMA, collagen I, CTGF and fibronectin, and restored the wound-healing ability inhibited by TGFβ. MenSCs induced Hippo/TAZ pathway activation, resulting in nuclear export and cytoplasmic retention of TAZ. TAZ inhibition was demonstrated to have similar effects even in the absence of MenSCs, and inhibition of TAZ was sufficient to attenuate TGFβ-mediated myofibroblast activation. LARGE SCALE DATA N/A. LIMITATIONS, REASONS FOR CAUTION This study included only in vitro experiments. Thus, additional data from in vivo experiments are needed in a future study. WIDER IMPLICATIONS OF THE FINDINGS The Hippo/TAZ pathway may be an important therapeutic target for endometrial fibrosis. STUDY FUNDING/COMPETING INTEREST(S) This study was supported by the National Natural Science Foundation of China (No. 81601236) and Zhejiang Provincial Natural Science Foundation of China (LY19H040009).

Abstract
Endometriosis has several distinguishing features in the ectopic endometrium, including chronic inflammation and fibrosis. According to the retrograde menstruation theory, endometriotic cells are derived from eutopic endometrial cells, and adhesion of endometrial cells to the extracellular matrix can be the initial step in the development of endometriosis. Therefore, we hypothesized that cell adhesion, which mediates a sequence of events in the development of endometriosis triggering inflammatory responses and tissue fibrosis could be a possible therapeutic target for endometriosis. We found co-upregulation of focal adhesion kinase (FAK) and monocyte chemoattractant protein-1 (MCP-1) in the endometriotic tissues compared with that in the normal endometrium. MCP-1 secretion was significantly higher in the endometriotic stromal cells than in the eutopic endometrial stromal cells. Furthermore, co-culture of U937 cells and endometriotic stromal cells upregulated secretion of transforming growth factor-β1 (TGF-β1). A FAK inhibitor significantly inhibited the secretion of MCP-1 in the endometriotic stromal cells and TGF-β1 in the co-culture with macrophages. FAK inhibitor treatment in the murine endometriosis model demonstrated a decrease in the formation of endometriotic lesions as well as the expression of MCP-1 and TGF-β1. Our results suggest that the FAK-mediated sequential development of endometriosis, including inflammatory response and tissue fibrosis, can be a new therapeutic target in endometriosis.

Reprod Biol Endocrinol 2020; 18:31. [PMID: 32299427 PMCID: PMC7161200 DOI: 10.1186/s12958-020-00590-3] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/03/2020] [Accepted: 04/13/2020] [Indexed: 01/09/2023] Open
Abstract
BACKGROUND A number of microRNAs are aberrantly expressed in endometriosis and are involved in its pathogenesis. Our previous study demonstrated that has-miR-100-5p expression is enhanced in human endometriotic cyst stromal cells (ECSCs). The present study aimed to elucidate the roles of has-miR-100-5p in the pathogenesis of endometriosis. METHODS Normal endometrial stromal cells (NESCs) were isolated from normal eutopic endometrium without endometriosis. Using hsa-miR-100-5p-transfected NESCs, we evaluated the effect of hsa-miR-100-5p on the invasiveness of these cells by Transwell invasion assay and in-vitro wound repair assay. We also investigated the downstream signal pathways of hsa-miR-100-5p by microarray analysis and Ingenuity pathways analysis. RESULTS hsa-miR-100-5p transfection enhanced the invasion and motility of NESCs. After hsa-miR-100-5p transfection, mRNA expression of SWItch/sucrose non-fermentable-related matrix-associated actin-dependent regulator of chromatin subfamily D member 1 (SMARCD1) was significantly attenuated. Whereas, the expression of matrix metallopeptidase 1 (MMP1) mRNA and active MMP1 protein levels was upregulated. CONCLUSION We found that SMARCD1/MMP-1 is a downstream pathway of hsa-miR-100-5p. hsa-miR-100-5p transfection enhanced the motility of NESCs by inhibiting SMARCD1 expression and MMP1 activation. These findings suggest that enhanced hsa-miR-100-5p expression in endometriosis is involved in promoting the acquisition of endometriosis-specific characteristics during endometriosis development. Our present findings on the roles of hsa-miR-100-5p may thus contribute to understand the epigenetic mechanisms involved in the pathogenesis of endometriosis.

Abstract
Uterine has a pivotal role in implantation and conceptus development. To prepare a conducive uterine condition for possibly new gestation during the estrous cycle, uterine endometrium undergoes dramatic remodeling. In addition, angiogenesis is an indispensable biological process of endometrium remodeling. Furthermore, essential protein expressions related to important biological processes of endometrium remodeling, which are vascular endothelial growth factor (VEGF), myoglobin (MYG), collagen type IV (COL4), fucosyltransferase IV (FUT4), and cysteine-rich protein 2 (CRP2), were detected in the endometrial tissue reported in many previous studies and recently discovered in histotroph substrates during the estrous cycle. Those proteins, which are liable for provoking new vessel development, cell proliferation, cell adhesion, and cell migration, were expressed higher in the histotroph during the luteal phase than follicular phase. Histotroph proteins considerably contribute to endometrium remodeling during the estrous cycle. To that end, the following review will discuss and highlight the relevant information and evidence of the uterine fluid proteins as endometrial-secreted factors that adequately indicate the potential role of the uterine secretions to be involved in the endometrial remodeling process.

Abstract
Intrauterine adhesion (IUA) is characterized by endometrial fibrosis, which ultimately leads to menstrual abnormalities, infertility, and recurrent miscarriages. The Shh/Gli2 pathway plays a critical role in tissue fibrogenesis and regeneration; Gli2 activation induces profibrogenic effects in various tissues, such as the liver and kidney. However, the role of Gli2 in endometrial fibrosis remains unknown. The purpose of this study was to test the hypothesis that activated Gli2 promotes endometrial fibrosis. Endometrial samples from moderate and severe IUA patients exhibited significantly enhanced expression of Gli2 compared with normal endometrial samples and mild IUA samples. Transfection with overactive Gli2 plasmids induced higher fibrosis-related protein expression, while blocking Gli2 signaling with cyclopamine caused the opposite effect in endometriotic stromal cells (ESCs), including inducing cell-cycle arrest. Menstrual-derived stem cell conditioned medium (MenSCs-CM) reduced endometrial fibrosis by reducing Gli2 protein levels and causing cell-cycle arrest in ESCs through granulocyte-colony stimulating factor (G-CSF). The effect was weakened after neutralization with a G-CSF antibody. Gli2 overexpression reduced the effects of MenSC-CM and G-CSF on fibrosis and cell-cycle progression in vitro. The antifibrotic effect of G-CSF was also observed in murine model. These findings demonstrate that Gli2 signaling promotes endometrial fibrosis, and the inhibition of Gli2 through MenSCs-secreted G-CSF may be of therapeutic value for managing endometrial fibrosis.

Abstract
Multiple studies have confirmed that human menstrual blood-derived stem cells (MenSCs) have potential applications in regenerative medicine or cell therapy. However, the contribution of MenSCs to endometrial repair is currently unknown. We evaluated the protective effects of MenSCs on impaired endometrial stromal cells (ESCs), as well as the signaling pathways involved in this process. Mifepristone was used to damage human ESCs, which were subsequently cocultured with MenSCs. The proliferation, apoptosis, and migration of ESCs were assessed, together with the expression of related signaling proteins including total p38 mitogen-activated protein kinase, P-p38, total protein kinase B (AKT), P-AKT, β-catenin, and vascular endothelial growth factor (VEGF). MenSCs significantly recovered the proliferation and migration ability of impaired ESCs, inhibited ESC apoptosis, and upregulated protein expression of P-AKT, P-p38, VEGF, and β-catenin. Our findings suggest that MenSC-based therapies could be promising strategies for the treatment of endometrial injury, and that AKT and p38 signaling pathways may be involved in this process.

Effects of Zearalenone Exposure on the TGF-β1/Smad3 Signaling Pathway and the Expression of Proliferation or Apoptosis Related Genes of Post-Weaning Gilts. Toxins (Basel) 2018; 10:toxins10020049.

Abstract
Zearalenone (ZEA) is an estrogenic toxin produced by Fusarium species, which is widely distributed and posed a great health risk to both humans and farm animals. Reproductive disorders associated with ZEA such as premature puberty, infertility and abortion have plagued the animal husbandry, but the molecular mechanism is unclear. Because transforming growth factor-β1 (TGF-β1) signaling pathway is involved in the proliferation and apoptosis of cells, proliferating cell nuclear antigen (PCNA), B-cell lymphoma/leukemia-2 (BCL-2) and BCL-2 associated X protein (BAX) that all play indispensable roles in the normal development of the uterus, it is hypothesized that ZEA induces reproductive disorders is closely related to the expression of these genes. The objective of this study was to assess the effects of dietary ZEA at the concentrations of 0.5 to 1.5 mg/kg on the mRNA and protein expression of these genes in the uteri of post-weaning gilts and to explore the possible molecular mechanism. Forty healthy post-weaning female piglets (Duroc × Landrace × Large White) aged 38 d were randomly allocated to basal diet supplemented with 0 (Control), 0.5 (ZEA0.5), 1.0 (ZEA1.0), or 1.5 (ZEA1.5) mg/kg purified ZEA, and fed for 35 d. Piglets were euthanized at the end of the experiment and samples were taken and subjected to immunohistochemistry, qRT-PCR and Western blot analyses. The relative mRNA expressions of PCNA, BCL-2 and Smad3 in the uteri of post-weaning gilts increased linearly (p < 0.05) and quadratically (p < 0.05) as ZEA concentration increased in the diet. The relative protein expressions of PCNA, BAX, BCL-2, TGF-β1, Smad3, and phosphorylated Smad3 (p-Smad3) in the uteri of post-weaning gilts increased linearly (p < 0.05) and quadratically (p < 0.001) with an increasing level of ZEA. The results showed that uterine cells in the ZEA (0.5–1.5 mg/kg) treatments were in a high proliferation state, indicating that ZEA could accelerate the proliferation of uteri and promote the development of the uteri. At the same time, the results suggested that ZEA activates the TGF-β1/Smad3 signaling pathway, suggesting it plays an important role in accelerating the development of the uterus.

Abstract
Objectives The dentin matrix servers as a reservoir of growth factors, sequestered during dentinogenesis. The aim of this study was to assess the viability and proliferation of dental pulp stem cells in the presence of dentin matrix-derived non-collagenous proteins and two growth factors; platelet-derived growth factor BB and transforming growth factor beta 1. Material and Methods The dental pulp cells were isolated and cultured. The dentin proteins were extracted and purified. The MTT assay was performed for assessment of cell viability and proliferation in the presence of different concentrations of dentin proteins and growth factors during 24 - 72 h post-treatment. Results The cells treated with 250 ng/mL dentin proteins had the best viability and proliferation ability in comparison with other concentrations (P < 0.05). The MTT assay demonstrated that cells cultured with 5 ng/mL platelet-derived growth factor BB had the highest viability at each time point as compared to other groups (P < 0.05). However, in presence of platelet-derived growth factor BB alone and in combination with transforming growth factor beta 1 and dentin proteins (10 ng/mL), significant higher viability was seen at all time points (P < 0.05). The least viability and proliferation at each growth factor concentration was seen in cells treated with combination of transforming growth factor beta 1 and dentin proteins at 72 h (P < 0.05). Conclusions The results indicated that the triple combination of growth factors and matrix-derived non-collagenous proteins (especially at 10 ng/mL concentration) has mitogenic effect on dental pulp stem cells.

Abstract
BACKGROUND Mechanisms underlying early reproductive loss in the human are beginning to be elucidated. The migratory and invasive capacity of human endometrial stromal cells (ESCs) is increasingly recognized to contribute to the intense tissue remodelling associated with embryo implantation, trophoblast invasion and endometrial regeneration. In this review, we examine the signals and mechanisms that control ESC migration and invasion and assess how deregulation of these cell functions contributes to common reproductive disorders. METHODS The PubMed database was searched for publications on motility and invasiveness of human ESCs in normal endometrial function and in reproductive disorders including implantation failure, recurrent pregnancy loss (RPL), endometriosis and adenomyosis, covering the period 2000-2012. RESULTS Increasing evidence suggests that implantation failure and RPL involve abnormal migratory responses of decidualizing ESCs to embryo and trophoblast signals. Numerous reports indicate that endometriosis, as well as adenomyosis, is associated with increased basal and stimulated invasiveness of ESCs and their progenitor cells, suggesting a link between a heightened menstrual repair response and the formation of ectopic implants. Migration and invasiveness of ESCs are controlled by a complex array of hormones, growth factors, chemokines and inflammatory mediators, and involve signalling through Rho GTPases, phosphatidylinositol-3-kinase and mitogen-activated protein kinase pathways. CONCLUSIONS Novel concepts are extending our understanding of the key functions of ESCs in effecting tissue repair imposed by cyclic menstruation and parturition. Migration of decidualizing ESCs also serves to support blastocyst implantation and embryo selection through discriminate motile responses directed by embryo quality. Targeting regulatory molecules holds promise for developing new strategies for the treatment of reproductive disorders such as endometriosis and recurrent miscarriage; and harnessing the migratory capacity of progenitor mesenchymal stem cells in the endometrium may offer new opportunities in regenerative medicine.

Abstract
BACKGROUND Decidualization (differentiation) of the endometrial stromal cells during the secretory phase of the menstrual cycle is essential for successful implantation. Transforming Growth Factor β1 (TGFβ1) canonically propagates its actions via SMAD signalling. A role for TGFβ1 in decidualization remains to be established and published data concerning effects of TGFβ1 on markers of endometrial decidualization are inconsistent. METHODOLOGY/PRINCIPAL FINDINGS Non-pregnant endometrial stromal cells (ESC) and first trimester decidual stromal cells (DSC) were cultured in the presence or absence of a decidualizing stimulus. Incubation of ESCs with TGFβ1 (10 ng/ml) down-regulated the expression of transcripts encoding the decidual marker proteins prolactin (PRL), insulin-like growth factor binding protein-1 (IGFBP-1) and tissue factor (TF). TGFβ1 also inhibited secretion of PRL and IGFBP-1 proteins by ESCs and surprisingly this response preceded down-regulation of their mRNAs. In contrast, DSCs were more refractory to the actions of TGFβ1, characterized by blunted and delayed down-regulation of PRL, IGFBP-1, and TF transcripts, which was not associated with a significant reduction in secretion of PRL or IGFBP-1 proteins. Addition of an antibody directed against TGFβ1 increased expression of IGFBP-1 mRNA in decidualised cells. Knockdown of SMAD 4 using siRNAs abrogated the effect of TGFβ1 on expression of PRL in ESCs but did not fully restore expression of IGFBP-1 mRNA and protein. CONCLUSIONS/SIGNIFICANCE TGFβ1 inhibits the expression and secretion of decidual marker proteins. The impact of TGFβ1 on PRL is SMAD-dependent but the impact on IGFBP1 is via an alternative mechanism. In early pregnancy, resistance of DSC to the impact of TGFβ1 may be important to ensure tissue homeostasis.

Abstract
CONTEXT Decidualization of the endometrium involves the morphological and biochemical reprogramming of the estrogen-primed proliferative endometrial stromal compartment under the continuing influence of progesterone. OBJECTIVES The aim of this study was to evaluate the involvement of the extracellular matrix contractility of eutopic and ectopic endometrial stromal cells during the tissue remodeling processes associated with decidualization. DESIGN The effect of decidualization on the contractile profile of the endometriotic cyst stromal cells and eutopic endometrial stromal cells with or without endometriosis in the three-dimensional collagen gel culture was investigated using laser scanning microscopy, collagen gel contraction assays, and Western blot analysis. RESULTS Decidualized ectopic and eutopic endometrial stromal cells in the three-dimensional collagen gel culture mimicked the morphology of decidual tissue in vivo. In vitro decidualization inhibited the contractility of these eutopic and ectopic endometrial stromal cells. Down-regulation of integrin alpha1beta1 and alpha2beta1 expression, suppression of Ras homology A (Rho A), Rho-associated coiled-coil-forming protein kinase (ROCK)-I and ROCK-II expression, inhibition of the differentiation into the myofibroblastic phenotype, and induction of differentiation into epithelioid decidual phenotype were observed in these cells during decidualization. CONCLUSIONS It is suggested that the attenuation of eutopic endometrial stromal cell-mediated contractility by decidualization is a novel and integral mechanism of the physiological endometrial tissue remodeling process during menstrual cycles. Although ectopic endometrial stromal cells have enhanced contractile profile, decidualization can attenuate the contractility of these cells. These findings may be one of the action mechanisms by which oral contraceptives and progestins ameliorate endometriosis.

Abstract
OBJECTIVE The aim of this study is to evaluate the involvement of tumor necrosis factor (TNF)-alpha in endometrial tissue remodeling during the perimenstrual period. STUDY DESIGN Human endometrial stromal cells (ESCs) were isolated from eight premenopausal patients in the late secretory phase. The effects of TNF-alpha on the contractility of cultured ESCs were investigated by collagen gel contraction assay. The effects of TNF-alpha on the proliferation of ESCs were also assessed by a modified methylthiazoletetrazolium assay. RESULTS TNF-alpha significantly upregulated the collagen gel contractility of ESCs in a dose-dependent manner. TNF-alpha did not affect ESC proliferation. CONCLUSION The results suggest that TNF-alpha may promote endometrial tissue repair by stimulating the contraction of the extracellular matrix by ESCs. By regulating ESC function during the perimenstrual period, TNF-alpha may be involved in the physiological tissue remodeling of the cyclic endometrium.

Abstract
BACKGROUND Excessive fibrosis is frequently associated with endometriosis. To evaluate the involvement of the extracellular matrix contractility of endometriotic stromal cells (ECSCs) in the pathogenesis of endometriosis-associated fibrosis, we compared the collagen gel contractility of cultured ECSCs with that of normal endometrial stromal cells. To clarify the mechanism underlying collagen gel contraction by ECSCs, we also evaluated the effect of (+)-(R)-trans-4-(1-aminoethyl)-N-(4-pyridyl) cyclohexanecarboxamide dihydrochloride, monohydrate (Y-27632), a selective Rho-associated coiled-coil-forming protein kinase (ROCK) inhibitor, on the collagen gel contraction by ECSCs. METHODS AND RESULTS ECSCs showed enhanced collagen gel contractility in comparison with NESCs. Myofibroblastic differentiation and the increased expression of fibronectin, RhoA, ROCK-I and ROCK-II proteins were observed with ECSCs using the 3D culture. Y-27632 significantly inhibited the collagen gel contractility of ECSCs without cytotoxicity. CONCLUSIONS The present findings suggest that the enhanced collagen contractility in ECSCs is associated with myofibroblastic differentiation, the increased expression of fibronectin and the activation of the Rho-ROCK-mediated signalling pathway, all of which may be involved in the pathogenesis of endometriosis-associated fibrosis. These results suggest that the inhibition of the Rho-ROCK-mediated signalling pathway may provide a novel strategy for the treatment of this disease. In addition, our experimental system of ECSCs using 3D collagen gel culture would be suitable for evaluating novel treatments for endometriosis.

Abstract
Endometriosis is an estrogen-correlated benign disease characterized by a marked ability of endometrial-like cells to invade and proliferate outside uterine cavity, resembling for some invasive aspect the cancer growth. The molecular mechanisms regulating endometrial cell invasiveness are mostly unknown, although interactions between extracellular matrix (ECM) proteins and their transmembrane receptors, integrins, are likely to play a central role. In particular, laminin (Ln)-5 could be closely involved, as it is in cancer. We have investigated the expression of Ln-1, Ln-5, and collagen IV (Coll IV) ECM proteins and their receptors, alpha3beta1 and alpha6beta4 integrins, in atrophic, proliferative, and secretive endometrium and in endometriosis. The results show that Ln-5, but not Ln-I and Coll IV, is altered in secretive endometrium as well as in endometriosis tissues. No alterations are observed in atrophic or proliferative endometrium. Consistently, the polarization of both integrin subunits alpha3 and beta1, but not alpha6 and beta4, is altered in secretive endometrium and endometriosis tissues, but not in atrophic and proliferative endometrium. These results seem to suggest that Ln-5 and alpha3beta1 could be involved in the invasive mechanism of endometriosis. The altered expression of Ln-5, by upregulating matrix metalloproteases activity, suggest an invading process similar to that of many cancer processes.
