Epigenetic regulation in mammalian preimplantation embryo development
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...
متن کاملGene expression during preimplantation mouse development.
To develop a resource for the identification and isolation of genes expressed in the early mammalian embryo, large and representative cDNA libraries were constructed from unfertilized eggs, and two-cell, eight-cell, and blastocyst-stage mouse embryos. Using these libraries, we now report the first stages at which the cytokines interleukin (IL)-6, IL-1 beta, and interferon (IFN)-gamma are transc...
متن کاملChromosome methylation patterns during mammalian preimplantation development.
DNA methylation patterns were evaluated during preimplantation mouse development by analyzing the binding of monoclonal antibody to 5-methylcytosine (5-MeC) on metaphase chromosomes. Specific chromosome patterns were observed in each cell stage. A banding pattern predominated in chromosomes at the one-cell stage. Banding was replaced at the two-cell stage by an asymmetrical labeling of the sist...
متن کاملRegulation of preimplantation development of bovine embryos by interleukin-1beta.
Experiments were performed to determine the actions of recombinant bovine interleukin-1beta (IL-1beta) on the growth of preimplantation embryos. In the first series of studies, IL-1beta was added at 8-10 h after insemination, and the percentage of oocytes developing to the blastocyst stage was evaluated. IL-1beta increased development to the blastocyst stage when embryos were cultured at high d...
متن کاملRegulation of preimplantation embryo development by brain-derived neurotrophic factor.
Hormonal factors secreted by embryos and reproductive tracts are important for successful development of preimplantation embryos. We found expression of brain-derived neurotrophic factor (BDNF) and neurotrophin-4/5 (NT-4/5) transcripts at its highest levels in the blastocyst stages. The transcripts for their receptor, TrkB, were detectable throughout the early embryonic stages with an increase ...
