An open question is whether the blastomeres became different as opposed to originating as different. Here we wanted to test two conflicting models: one proposing that each blastomere contains both animal and vegetal materials in balanced proportions because the plane of first cleavage runs close to the animal-vegetal axis of the fertilized oocyte; and the other model proposing that each blastomere contains variable proportions of animal and vegetal materials because the plane of the first cleavage can vary depending on the topology of fertilization. Therefore, we imposed the fertilization site in three distinct regions of mouse oocytes (animal pole, vegetal pole, equator) via intracytoplasmic sperm injection (ICSI). After the first zygotic cleavage, the sister blastomeres were dissociated and subjected to single-cell transcriptome analysis, keeping track of the original pair associations. Non-supervised hierarchical clustering revealed that the frequency of correct pair matches varied with the fertilization site (vegetal pole > animal pole > equator), thereby, confuting the first model of balanced partitioning. However, the inter-blastomere differences had similar signatures of gene ontology across the three groups, thereby, also confuting the competing model of variable partitioning. These conflicting observations could be reconciled if animal and vegetal materials segregated at the first cleavage: an event considered improbable and possibly deleterious in mammals. We tested this occurrence by keeping the fertilized oocytes immobilized from the time of ICSI until the first cleavage. Image analysis revealed that cleavage took place preferentially along the short (ie equatorial) diameter of the oocyte, thereby partitioning the animal and vegetal materials into the 2-cell blastomeres. Our results point to a simple mechanism by which the two sister blastomeres start out as different, rather than becoming different.</p>","PeriodicalId":18759,"journal":{"name":"Molecular human reproduction","volume":" ","pages":""},"PeriodicalIF":3.6,"publicationDate":"2024-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142951852","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the molecular mechanisms driving crosstalk between stromal cells and epithelial glands, along with paracrine signaling underlying lesion development and progression, are still poorly understood. Exosomes, small cell-derived carriers and microRNAs, namely non-coding RNA molecules, are crucial to intercellular communication within the endometrium and may elucidate interactions between the two compartments that contribute to adenomyotic lesion formation. To our knowledge, this is the first foundational study to comprehensively isolate and characterize stroma-derived exosomes from women with adenomyosis. Exosome isolation by means of differential ultracentrifugation was validated in 22 samples, including 11 healthy subjects and 11 women with adenomyosis, using nanoparticle tracking analysis, transmission electron microscopy and flow cytometry. Profiling of microRNA in secreted exosomes revealed 10 microRNAs with significantly altered expression in adenomyosis subjects during the menstrual phase compared to controls. Thorough investigations into menstruation-specific molecular mechanisms, as well as predicted target genes and enriched pathways of exosomal microRNAs, offer promising insights into the pathogenesis of adenomyosis, shedding light on the potential mechanisms underlying stromal cell signaling and adenomyotic lesion establishment. This work does, however, have certain drawbacks, including modest sample size and limited representation due to a lack of readily available endometrial biopsies in the menstrual phase. Having done the groundwork in this study, future research should seek to validate these findings in larger cohorts and apply functional assays.

The aim of the current research is to study the effect of aneuploidy of somatic ovarian cells on gene expression in ovarian cortex stromal cells and small ovarian follicles from mosaic (45,X/46,XX) Turner syndrome patients. To this end, ovarian cortical tissue was obtained by laparoscopic surgery from eight mosaic Turner syndrome patients (aged 5-19 years) and eight controls (aged 6-18 years). The tissue was fractionated to obtain purified follicles and stromal cells. Part of the purified fractions was used to determine the X chromosomal content of ovarian cells of Turner syndrome patients by interphase FISH, while the remaining part was used to compare the gene expression profile of these cells to controls. The results demonstrated that high level 45,X haploidy in cortical stromal cells of Turner syndrome patients had no effect on gene expression, gross morphology of the ovary, or histological appearance of the cortex compared to controls. Gene expression analysis of purified small follicles of Turner syndrome patients with mainly 45,X granulosa cells revealed aberrant expression of 11 genes. Of these, six were upregulated (CD24, TLR1, EPHA2, PLXND1, ST6GALNAC5, and NOX4) while five genes (CRYAB, DLX1, PCYT2, TNFRSF8, and CA12) were downregulated compared to follicles of controls. Interestingly, the overexpressed genes in these small follicles were all associated with more advanced stages of follicular development.

We evaluated the potential of mTOR inhibitors as therapeutic agents for endometriosis, examined the secondary benefits related to reproductive function, and assessed how their side effects can be managed. We conducted a thorough review of publications on the role of the mTOR pathway and the effectiveness of mTOR inhibitors in endometriosis patients. These results indicate that the mTOR pathway is activated in endometriosis. Additionally, mTOR inhibitors have shown efficacy as monotherapies for endometriosis. They may alleviate resistance to hormonal therapy in endometriosis, suggesting a potential synergistic effect when used in combination with hormonal therapy. The potential reproductive benefits of mTOR inhibitors include decreased miscarriage rates, improved implantation, and prevention of age-related follicular loss and ovarian hyperstimulation syndrome. Activation of the mTOR pathway has also been implicated in the malignant transformation of endometriosis. Preclinical studies suggest that the dosage of mTOR inhibitors needed for treating endometriosis may be lower than that required for anticancer or immunosuppressive therapy, potentially reducing dosage-dependent side effects.

Additionally, an EV uptake study further showed that EMS-EVs were preferentially taken up by ESCs rather than by endometrial epithelial cells.

The human endometrium undergoes remodeling within each menstrual cycle to prepare or become receptive to an implanting blastocyst in the mid-secretory phase.

Recently, using hormone-treated endometrial organoids to model receptivity, we identified that the transcriptional regulator WD-repeat-containing protein-61 (WDR61) was reduced in organoids derived from infertile women. In this study, we aimed to determine the role of WDR61 in endometrial receptivity. Here, we demonstrated that WDR61 immunolocalizes in the nuclei and cytosol of endometrial glandular epithelium, luminal epithelium, and stroma. The staining intensity of WDR61 was significantly higher during the receptive mid-secretory phase compared to the non-receptive proliferative phase in fertile women. In a functional experiment to model blastocyst adhesion to the endometrial epithelium, we found that adhesion of cytotrophoblast progenitor spheroids was blocked when siRNA was used to knockdown WDR61 in primary endometrial epithelial cells. Similarly, in Ishikawa cells (a receptive human endometrial epithelial cell line), siRNA knockdown of WDR61 significantly reduced the cell adhesive and proliferative capacities. qPCR revealed that WDR61 knockdown reduced expression of key genes involved in receptivity including HOXD10, MMP2, and CD44. Chromatin immunoprecipitation sequencing demonstrated that WDR61 directly targeted 2022 genes in Ishikawa cells, with functions including focal adhesion, intracellular signaling and epithelial-mesenchymal transition.

Follicular IL-22 levels were significantly lower in PCOS patients than in the control group and were positively correlated with oocyte fertilization rate and high-quality embryo rate. Additionally, IL-22 evidently improved follicle development in vitro and promoted ovulation-related gene expression, which was disrupted by the depletion of interleukin-22 receptor 1 (IL-22R1) or inhibition of STAT3 in granulosa cells.
