Methanol induces developmental toxicity in rats and mice producing exencephaly, cleft palate, cervical skeletal defects, reduced body weight, and increased embryo/fetal death. Exposure to methanol in whole embryo culture also induces developmental retardation, dysmorphogenesis, and embryo lethality. In the present study, cultured rat and mouse embryos were exposed to methanol and subsequently o...
Background: The process of implantation involves the interaction of the human embryo and the uterine epithelium. Failure of implantation is a major reason for infertility in women and the inability to achieve endometrial receptivity is responsible for much of the failure of reproductive technologies. Management of repeated implantation failure despite transfer of good-quality embryos still rema...
Preimplantation Genetic Diagnosis T he opportunity to exclude in-vitro derived embryos with documented genetic abnormalities before the initiation of pregnancy is an attractive means of preventing heritable genetic disease. Currently couples who are carriers of genetic disease have the option of undergoing chorionic villus sampling in the first trimester or amniocentesis in the second trimester...
objective: experiments were conducted to find the differences between post-thaw viability and chromosome aberrations in eight-cell mouse embryos at presence of dimethyl sulfoxide (dmso) and 1, 2-propanediol (proh) as croprotectants in different storage durations. materials and methods: in this case-control study, a total number of 720 mouse embryos from about 250 nmri mice were vitrified with 3...
Preimplantation embryo development involves four stages: fertilization, cell cleavage, morula and blastocyst formation. During these stages, maternal and zygotic epigenetic factors play crucial roles. The gene expression profile is changed dramatically, chromatin is modified and core histone elements undergo significant changes. Each preimplantation embryo stage has its own characteristic epige...
The Deciphering the Mechanisms of Developmental Disorders (DMDD) consortium is a research programme set up to identify genes in the mouse, which if mutated (or knocked-out) result in embryonic lethality when homozygous, and initiate the study of why disruption of their function has such profound effects on embryo development and survival. The project uses a combination of comprehensive high res...
Although much is known about the embryo during implantation, the architecture of the uterine environment in which the early embryo develops is not well understood. We employed confocal imaging in combination with 3D analysis to identify and quantify dynamic changes to the luminal structure of murine uterus in preparation for implantation. When applied to mouse mutants with known implantation de...
Di(2-ethylhexyl)phthalate (DEHP) is a plasticizer in a variety of consumer products. Given the adverse toxicity effects of DEHP on living organisms, its high consumption and dispersal has been caused a serious concern. . Nowedays, the Fish Embryo Test (FET) method is widely used among the conventional methods of toxicology .The aim of the this study was to determine the acute toxicity of Di(2-e...
