Effects of iloprost on embryo development in vitro
Apoptosis (programmed cell death) can occur in embryos at any point during development. Apoptosis can occur naturally in embryo development due to a myriad of reasons including suboptimal culture conditions. It has recently been reported that Iloprost, a biosynthetic prostacyclin analogue and …

Mouse Embryo Development in the Presence of Capsaicin
… cross the blood/placenta barrier and affect an embryo in utero. In order to assay the potential for toxicity to human embryos, mouse embryos were exposed to capsaicin and the effect of the capsaicin on embryo development was measured. Embryos were co-cultured in Krebs medium with 1% ethanol and …

The effects of propylparaben on preimplantation embryo development
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2022-11-11 without embargo terms

Influence of Growth Factors on Bovine Embryo Development
… to improve the in vitro production of cattle embryos by refining in vitro maturation (IVM) and culture systems. Cysteine supplementation to IVM media of bovine oocytes increases cellular glutathione production, which reduces reactive oxygen species (ROS). Similarly, beneficial effects of …

Karyopherin alpha subtypes and porcine early stage embryo development
… for coordinating cellular events during embryogenesis. The karyopherin α/β heterodimer is an intracellular nuclear trafficking system that mediates nuclear import of proteins that bear classical nuclear localization signals (NLSs). Seven karyopherin α subtypes have been identified in the …

Redefining the Gastrula Organiser in Early Chick Embryo Development
… body axes and inducing the formation of the embryonic nervous system. Hensen’s node was identified as the equivalent structure in birds due to its ability to induce a complete secondary axis with a regionalised neural tube when grafted to an ectopic location. The node also demonstrates …

A Genomic Perspective on Early Embryo Development in Cattle
In vitro embryo production (IVP) has revolutionized the cattle industry, but it still faces efficiency limitations compared to in vivo embryo production. With a major impact on it, a proper transcriptome profile is crucial for an embryo to undergo pre-implantation development and become …

Effect of immunoglobulins on early bovine embryo development in vitro
… [effect of immunoglobulins (Ig) on early bovine embryo development in vitro. Fifty-four cows superovulations were conducted in 36 cows with follicle stimulating hormone. Embryos were collected by non-surgical procedures and morphologically evaluated and randomly assigned to culture. Embryos were …

Isoform-Specific Expression During Embryo Development in Arabidopsis and Soybean
… that are produced during Arabidopsis and soybean embryo development. I developed several data analysis pipelines for the detection and the functional characterization of active splice variants and splicing factors that arise during embryo development. The main goal of this dissertation was to …

GENETIC NETWORK CONTROLLING FEMALE GAMETOPHYTE AND EMBRYO DEVELOPMENT IN ARABIDOPSIS THALIANA
… the molecular understanding of genes regulating embryo sac development. The identification of genes involved in female gametophyte formation is of significant interest since they are of great importance for plant reproduction. In the last year, different researches have been done in order to …

Momentary exposure to a microfluidic environment seems to enhance embryo development
… need for an objective and non-invasive method of embryo selection to allow for single embryo transfer is needed to increase the success rates and while simultaneously decreasing the multiple birth rates. One such method being tested uses a device that measures the specific gravity (SG) of embryos …

Global Expression Profiles and Targeted Pathway Modulation During Soybean Embryo Development
In the second approach, five CHS transgenic soybean lines were generated. Relative mRNA abundance of transgenic and endogenous CHS genes was measured by real-time PCR. Three lines showed low transgene expression but increased transcript abundance for two endogenous CHS genes One line showed a …

The effects of environmentally relevant toxicants on female reproduction and embryo development
… on the effects of phthalates on preimplantation embryos. Of these studies, most have shown that exposure to a single phthalate such as Di (2-ethylhexyl) phthalate (DEHP) and other EDCs have adverse effects on proper embryo development. However, there are limited data on the effects of exposure to …

The effect of uterine flushings on early bovine embryo development in vitro
… on day 6, 10, or 15 post insemination on early embryo development. Ninety-eight cows were superovulated with follicle stimulating hormone. Embryos were collected by non-surgical flushing procedures and morphologically evaluated and randomly assigned to culture. Embryos were cultured in Ham's …

Bioinformatics Investigation on the Role of Obox Gene Family in Preimplantation Embryo Development
<p>Preimplantation embryo development (PED) refers to the period from fertilization to implantation in mammals. This complex process is critical for successful implantation and pregnancy. Although studies on PED have been conducted, using mainly the mouse as a model organism, the gene regulatory …

Leukemia Inhibitory Factor (LIF): Murine Preimplantation Embryo Development, Implantation Rates, and Skeletal Development
… effects pre-implantation and post-implantation development. The objectives of this project were to determine the effects LIF on pre-implantation development, to determine the effects that it may have on implantation rates, successful pregnancy rates, and resorption rates, and to determine the …

Bitesize bundles F-actin and influences actin remodeling in syncytial Drosophila embryo development
… at earlier, syncytial stages of Drosophila embryo development. Btsz was required for the formation of stable pseudo-cleavage furrows that prevented spindle collisions and nuclear fallout prior to cellularization. While previous studies focused on Btsz isoforms containing the Moesin Binding …

Investigation of the role of chromosome missegregation in embryo development and in tumorigenesis
… force or merely a secondary effect of tumor development. In Chapter 2, I will present work showing that the protein most often altered in colon cancers, Adenomatous Polyposis Coli (AdPC) (Kinzler and Vogelstein 1996), is modified by members of the spindle assembly checkpoint and that a …
