The close physical proximity of early blood vessels observed in the placenta and the cytotrophoblast, as well as the reported production of vasculogenic growth factors by the latter, suggests that signalling between these two niches may be important. Here, we have developed an <em>in vitro</em> model to address the hypothesis that the cytotrophoblast, by the secretion of soluble factors, drives differentiation of resident sub-trophoblastic mesenchymal stem cells (MSCs) along a vascular lineage, thereby establishing feto-placental circulation. BM-MSCs (a readily available model for placental stem cells) were treated with conditioned medium containing the secretome from human BeWo trophoblast cells, or endothelial growth medium (EGM2) supplemented with exogenous growth factors (VEGF, IGF1 and EGF) for 10–12 days. Trophoblast-conditioned media, found to contain detectable concentrations of cytokines including VEGF, uPAR, TIMP-1, TIMP-2, IL6 and placental growth factor, induced the expression of the endothelial genes <em>CD31</em>, <em>von Willibrand factor</em> (<em>vWF</em>), <em>FLT-1</em>, <em>VEGFR2</em> and <em>VE-Cadherin</em>. Upregulation of vWF protein was also detected following growth in trophoblast-conditioned media, using immunocytochemistry. Wound healing (migration assay) and Matrigel-tube formation assays confirmed that the BM-MSCs cultured in trophoblast-conditioned media exhibited functional measures of endothelial cells in addition to expressing relevant markers. Identification of key trophoblast-secreted factors and their promotion of endothelial differentiation in BM-MSCs helps advance our theories regarding the close relationship of the mesenchymal stem cell-cytotrophoblast niche in coordinating the complex angiogenic events that occur in the placenta. The <em>in vitro</em> model presented here provides an accessible and reproducible tool for further investigations into placental development.</div></div>","PeriodicalId":21018,"journal":{"name":"Reproductive biology","volume":"25 1","pages":"Article 100994"},"PeriodicalIF":2.5,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143019196","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several reports suggest the possibility of the pathogenesis and recurrence of endometriosis being related to functions of stem/progenitor cells of the endometrium. The drawback of the widely used method of using Hoechst 33342, a fluorescent dye, to collect stem cell-like populations, is the requirement of an ultraviolet (UV) excitation source not commonly provided on standard flow cytometers. Here, we aimed to overcome this hurdle by establishing a novel method that uses DyeCycle Green (DCG), a cell-permeable DNA dye, for collecting a significantly higher fraction of stem cell-like side population (SP) from HHUA cells (human endometrial cancer cell line) with standard equipment without a UV laser. Furthermore, subculturing the DCG-SP cells expanded their population remarkably. The DCG-SP cells possessed stem cell-like characteristics with high expression of stem cell markers such as aldehyde dehydrogenase 1 A (ALDH1A), sushi domain containing 2 (SUSD2), increased colony formation ability, and high tumorigenicity in vivo, although the expression of some stem cell markers varied during expansion. We screened inhibitors for selective proliferation of the DCG-SP cells over immortalized endometrial cells (EM-E6/E7/hTERT-2 cells) and identified two effective compounds disulfiram and NSC319726. In addition, these compounds inhibited the colony formation and invasiveness of the DCG-SP cells.

Moreover, TX administration decreased oxidative stress markers and boosted antioxidants (superoxide dismutase, catalase, and reduced glutathione), suppressed and NF-κB p65 and pro-inflammatory cytokines [TNF-α (tumor necrosis factor-alpha) and IL-6 (interleukin-6)], and reduced apoptosis as depicted by testicular levels of caspase-3, Bcl-2, and Bax.

After an extensive literature search, we selected 25 articles for the systematic review. Bias analysis and methodological quality assessments were examined using the SYRCLE Risk of Bias tool. Moreover, 20 out of the 25 studies were eligible for performing a meta-analysis to evaluate the intensity of atrazine damage on the levels of intratesticular testosterone and serum follicle-stimulating hormone (FSH), luteinizing hormone (LH), testosterone, estradiol, and progesterone. The meta-analysis revealed that atrazine exposure decreased serum FSH, LH, and testosterone levels, besides increased serum estradiol and progesterone levels. Atrazine also caused a reduction in intratesticular testosterone levels. Exposure to atrazine in high concentrations (≥ 100 mg Kg⁻¹) was the main cause of endocrine disruption, regardless of the exposure time. None of the studies have tested doses relevant to human health risk. Oxidative stress and inflammation are involved in atrazine toxicity, impairing the gonadotropin release by the pituitary, disturbing steroidogenesis, and affecting the male hormone regulatory system.

RBMS3 is a tumor suppressor implicated in several cancers, including ovarian cancer. Ferroptosis, a novel form of programmed cell death, is gaining attention in cancer research. This study explores whether metformin induces ferroptosis and inhibits ovarian cancer progression through the RBMS3 pathway. We used a CCK-8 assay to determine the optimal metformin concentration for ovarian cancer cells. Metformin’s effects were further evaluated using EdU assay and flow cytometry. To clarify its mechanism, we employed programmed cell death inhibitors and measured levels of MDA (Malondialdehyde), GSH (Glutathione), and Fe²⁺. Ferroptosis-related proteins and RBMS3 expression in ovarian cancer tissues and cells were assessed via RT-qPCR and Western blotting. A xenograft mouse model was used to observe metformin’s effects on tumor growth. Metformin inhibited the viability of ovarian cancer A2780 cells, promoted ferroptosis, increased MDA and Fe²⁺ levels, and reduced GSH. It upregulated ferroptosis-related genes while downregulating GPX4 and SLC7A11. Although RBMS3 was reduced in cancer cells, metformin increased its expression, and silencing RBMS3 reversed metformin’s effects. In vivo, metformin inhibited tumor growth, which was negated by RBMS3 silencing. Our findings suggest that metformin promotes ferroptosis and inhibits ovarian cancer progression by upregulating RBMS3, offering a promising direction for clinical application in ovarian cancer treatment.</div></div>","PeriodicalId":21018,"journal":{"name":"Reproductive biology","volume":"25 1","pages":"Article 100968"},"PeriodicalIF":2.5,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142848731","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dibutyryl-cAMP (dbcAMP), a well-known cAMP modulator, is used to inhibit the resumption of meiosis in immature oocytes. However, there is no information on the optimal timeframe for sustaining meiotic arrest to enhance oocyte maturity during IVM.

During the lecture and poster sessions, participants explored a wide range of topics, including gamete and early embryonic development, assisted reproduction and fertility preservation, embryo-maternal interactions and pregnancy processes, and the hormonal, neural, and immune regulation of reproduction. Additionally, the discussions covered the environmental impact on reproductive function, as well as the development and function of the gonads. Additionally, two workshop events were organized: ‘Milestones on the road to a fruitful scientific career” for young researchers with a PhD degree, and “How to live with research failures and not be discouraged” for PhD students, which gave young researchers an opportunity to exchange their experience in the scientific field and discuss possible ways of handling crises.
