Project description:Objective To investigate the influence that oviductal extracellular vesicles from patients with endometriosis exert on early embryo development. Design In vitro experimental study Setting University-affiliated hospital. Patient(s) Women with and without endometriosis who underwent hysterectomy (n = 15 in total). Intervention(s) None. Main Outcome Measure(s) Oviductal extracellular vesicles from patients with endometriosis (oEV-EMT) or without endometriosis (oEV-ctrl) were isolated and co-cultured with two-cell murine embryos for 75 hours. Blastocyst rates were recorded. RNA sequencing was used to identified the differentially expressed genes in blastocysts cultured either with oEV-EMT or with oEV-ctrl. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis were performed to identify potential biological processes in embryos that oEV-EMT affect. The functions of oEV on early embryo development were determined by reactive oxygen species (ROS) levels, mitochondrial membrane potentials, total cell numbers and apoptotic cell proportions. Result(s) Extracellular vesicles were successfully isolated from human Fallopian tubal fluid and their characterizations were described. The blastocyst rates were significantly decreased in the oEV-EMT group. RNA sequencing revealed that oxidative phosphorylation was down-regulated in blastocysts cultured with oEV-EMT. Analysis of oxidative stress and apoptosis at the blastocysts stage showed that embryos cultured with oEV-EMT had increased ROS level, decreased mitochondrial membrane potentials, and increased apoptotic index. Total cell numbers were not influenced. Conclusion(s) Oviductal extracellular vesicles from patients with endometriosis exert a negative influence on early embryo development.

Project description:The oviductal microenvironment is a site for key events that involve gamete maturation, fertilization and early embryo development. Secretions into the oviductal lumen by either the lining epithelium or by transudation of plasma constituents are known to contain elements conducive for reproductive success. Although previous studies have identified some of these factors involved in reproduction, knowledge of secreted proteins in the oviductal fluid remains rudimentary with limited definition of function even in extensively studied species like cattle. In this study, we used a shotgun proteomics approach followed by bioinformatics sequence prediction to identify secreted proteins present in the bovine oviductal fluid (in vivo) and secretions from the bovine oviductal epithelial cells (in vitro). From a total of 2087 proteins identified, 266 proteins could be classified as secreted, 109 (41%) of which were common for both in vivo and in vitro conditions. Pathway analysis indicated different classes of proteins that included growth factors, metabolic regulators, immune modulators, enzymes, and extracellular matrix components. Functional analysis revealed mechanisms in the oviductal lumen linked to immune homeostasis, gamete maturation, fertilization and early embryo development. These results point to several novel components that work together with known elements mediating functional homeostasis, and highlight the diversity of machinery associated with oviductal physiology and early events in cattle fertility.

Project description:Recently, extracellular vesicles, nanoparticles able to transfer functionally active cargo between cells, have emerged as important players in cell–cell communication, and as such, they have gained great attention over the past decade also in reproductive biology. To get a broader picture of transcriptomic changes evoked by extracellular vesicles cells in porcine conceptuses, trophoblast primary cells were exposed in vitro to uterine-derived extracellular vesicles (EVs).

Project description:Oviductal extracellular vesicles (oEVs) are emerging as key players in gamete/embryo-oviduct interactions contributing to successful pregnancy. Various positive effects of oEVs on gametes and early embryos have been found in vitro. To find out if these effects are associated with changes of embryonic gene expression, the embryonic transcriptome was analyzed after supplementation of bovine embryos with bovine oEVs during in vitro culture (IVC) in comparison to corresponding controls without oEVs. Embryos were cultured during 7 days of IVC with fresh oEVs, oEVs frozen after isolation from oviductal fluid or without oEVs (control), since a previous study showed different effects of fresh and frozen oEVs. Five pools of 10-14 embryos were analyzed for each group by low-input Illumina RNA-sequencing. Analysis of differential gene expression revealed 221 differentially expressed genes (DEGs) for the comparison of frozen oEVs vs control, 67 DEGs for fresh vs frozen oEVs, and only minor differences for the comparison fresh oEVs vs control (28 DEGs). An integrative analysis with the previously studied mRNA and small ncRNA content of bovine oEVs suggested direct effects of oEVs content on the embryonic transcriptome for the supplementation with frozen oEVs, i.e., increase of transcripts found in higher concentrations in oEVs and decrease of transcripts which are potential targets of miRNAs found in oEVs.

Project description:The oviducts play a critical role in gamete and embryo transport, as well as supporting fertilization and early embryo development. Progesterone receptor (PGR) is a transcription factor highly expressed in oviductal cells, while it’s activating ligand, progesterone (P4), surges to peak levels as ovulation approaches. P4 is known to regulate oviduct cilia beating and muscular contractions in vitro, but how PGR may mediate this in vivo is poorly understood. We used PGR-knockout (PRKO) mice to determine how PGR regulates oviductal function during the periovulatory period, in particular oviductal transport and embryo support. We used microarrays to identify putative PGR-regulated genes in the oviduct during the periovulatory period, a time when the oviduct is preparing to receive the newly-ovulated COC.

Project description:The mammalian oviduct is a complex, fibromuscular organ known for its role in orchestrating a series of timely and dynamic changes to suitably support early embryogenesis. Establishing successful reproductive outcomes are largely determined through effective and cohesive communication systems between the transient embryo and the maternal environment. Climate change-induced, Heat stress (HS), is one of the largest single stressors compromising reproductive function. Systemic changes in the redox status of the maternal environment, adversely affect fertilization and early embryonic development, negative causation of HS. Oviductal organoids represent a 3-dimensional, biomimetic model to study the physiological impact of HS on the physiology of the oviduct and the subsequent developing embryo. In this study, we aimed to generate a robust bovine oviductal organoid culture system to decrypt the oviducts' differential transcriptomic response to HS, to elucidate the impact of thermal stress on oviductal physiology with subsequent potential impacts on early embryo development.
