Recent studies indicate that communication between the bovine embryo and the mother begins in the oviduct. Here, we aimed to investigate the effect of embryos on bovine oviducts for their immune responses using an in vitro model. First, zygotes were cultured with or without bovine oviduct epithelial cells (BOECs) for 4 days, when embryos had reached the 16-cell stage. At that time, we detected interferon-tau (IFNT) in embryos co-cultured with BOECs, but not in embryos cultured alone. Next, peripheral blood mononuclear cells (PBMCs) were incubated either in media from embryo alone cultures or from co-cultures of embryos with BOECs...

We generated cattle embryos using mitochondrial supplementation and somatic cell nuclear transfer (SCNT), named miNT, to determine how additional mitochondrial DNA (mtDNA) modulates the nuclear genome. To eliminate any confounding effects from somatic cell mtDNA in intraspecies SCNT, donor cell mtDNA was depleted prior to embryo production. Additional oocyte mtDNA did not affect embryo development rates but increased mtDNA copy number in blastocyst stage embryos. Moreover, miNT-derived blastocysts had different gene expression profiles when compared with SCNT-derived blastocysts...

  BACKGROUND: In order to thaw slow-cooled bovine embryos it is standard practice to draw out permeating cryoprotectants by passing embryos through successively decreasing osmotic solutions. However, recently it has been suggested that sucrose may not be needed in the warming media. OBJECTIVE: The aim of this experiment was to compare the effect of warming media prepared with or without the inclusion of sucrose on the survival and hatching capacity of vitrified in vitro-derived bovine embryos...

Many studies have examined the impact of cell/embryo culture media on the development of human embryo during IVF process, but few studies have followed up and compared the effects of these culture media on the developmental outcome of children conceived by IVF. As recurrent experimental evidence from animal studies suggests potential long-term effects of embryo culture media on the health outcome of IVF-conceived children, more studies are needed to clarify the role of the culture media and mechanisms underlying such effects...

Recent studies suggest that Day-7 bovine embryo starts to communicate with the uterine epithelium through interferon-tau (IFNT) signaling. However, immune modulatory role of IFNT in the uterus just after the embryo moves from the oviduct is unclear. We aimed to examine the hypothesis that Day-7 bovine embryo secretes IFNT in the uterus, which induces anti-inflammatory response in immune cells. The uterine flush (UF) with multiple embryos was collected from Day-7 donor pregnant cows and peripheral blood mononuclear cells (PBMCs) were then cultured in UF...

Unlike oocytes of many other mammalian species, parthenogenetically activated hamster oocytes have not been reported to develop beyond the two-cell stage. This study investigated the in vitro development into blastocysts of parthenogenetic embryos of Golden Syrian hamsters. We observed that hamster oocytes could easily be artificially activated (AA) by treatment with ionomycin plus 6-dimethylaminopurine + cycloheximide + cytochalasin B as assessed by embryo cleavage in HECM-9 (63.15%) or HECM-10 (63.82%). None of the cleaved embryos developed beyond the two-cell stage when cultured in either of the two media...

INTRODUCTION: Domoic acid is a potent marine neurotoxin produced by certain species of the diatom genus Pseudonitzschia. To our knowledge, there are no studies that have investigated neurotoxic effects of domoic acid on dopaminergic neurons. Accordingly, the present study was carried out to investigate the potential neurotoxic effects of domoic acid on dopaminergic neurons in primary mesencephalic cell culture. MATERIAL AND METHODS: Cultures prepared from embryonic mouse mesencephala (total of 250 embryos) were treated with different concentrations of domoic acid (0...

In the temperate region, most common mycotoxins are members of fusariotoxins. It often happens that food and forage are contaminated with two or more fusariotoxins at the same time. Effects of co-contamination are poorly documented, especially in the field of reproduction. The aim of our study was to assess the combined effect of the two common fusariotoxins, T-2 toxin (T-2) and Fumonisin B1 on early mouse embryo development in vitro. Embryo culture media contained either (1) 0.5 ng/ml T-2; 1, 2, or 10 ng/ml FB1 (group A, B, and C, respectively); or (2) 0...

Antioxidants have been widely used during in vitro production to decrease the negative effect of reactive oxygen species. It was reported that the complex resveratrol-methyl β-cyclodextrin (RV-CD) improves resveratrol's stability and bioavailability and increases its antioxidant activity. This study evaluates the effect of RV-CD during in vitro oocyte maturation (IVM) or in vitro embryo culture (IVC) on developmental competence and quantitative changes in gene expression of developmental important genes. In experiment 1, RV-CD was added to IVM media and maturation level, embryo development and oocytes, cumulus cells, and blastocysts gene expression by RT-qPCR were examined...

Earlier evidence suggests, that the embryo signals to the maternal immune system. Extracellular vesicles (EVs) are produced by all types of cells, and because they transport different kinds of molecules from one cell to the other, they can be considered as means of intercellular communication. The aim of this work was to test, whether the embryo is able to produce sufficient amounts of EVs to alter the function of peripheral lymphocytes. Embryo-derived EVs were identified by their Annexin V biding capacity, and sensitivity to Triton X dependent lysis, using flow cytometry...

Undifferentiated spermatogonia eventually differentiate in the testis to produce haploid sperm. Within this cell population, there is a small number of spermatogonial stem cells (SSCs). SSCs are rare cells in the testis, and their cellular characteristics are poorly understood. Establishment of undifferentiated cell line would provide an indispensable tool for studying their biological nature and spermiogenesis/spermatogenesis in vitro. However, there have been few reports on the long-term culture of undifferentiated spermatogonia in species other than rodents...
