Dynamics of DNA Methylation during Early Development of the Preimplantation Bovine Embryo
There is species divergence in control of DNA methylation during preimplantation development. The exact pattern of methylation in the bovine embryo has not been established nor has its regulation by gender or maternal signals that regulate development such as colony stimulating factor 2 (CSF2). Using immunofluorescent labeling with anti-5-methylcytosine and embryos produced with X-chromosome so...
متن کاملThe Role of Glycoconjugates in Development of Floor Plate During Early Morphogenesis in Mouse Embryo
The floor plate is a small group of cells located at the ventral midline of neural tube. During early neurogenesis the floor plate plays critical role (s) in differentiation of ventral portion of neural tube.The purpose of this study was to determine the distribution of glycoconjugates in floor plate as well as underlying mesoderm (notochord) and their inductive activities in mouse embryos.Form...
متن کاملMethylation dynamics in the early mammalian embryo: implications of genome reprogramming defects for development.
In mouse and most other mammalian species, the paternal and maternal genomes undergo parent-specific epigenetic reprogramming during preimplantation development. The paternal genome is actively demethylated within a few hours after fertilization in the mouse, rat, pig, bovine, and human zygote, whereas the maternal genome is passively demethylated by a replication-dependent mechanism after the ...
متن کاملDNA methylation dynamics during oocyte and embryo development and its association with environmental induced alterations
Epigenetic mechanisms are fundamental to successful gametogenesis and development. The fertilized egg undergoes global DNA demethylation to facilitate remodelling from two differentiated gametespecific states to a pluripotent embryonic state. Maintenance of appropriate levels of DNA methylation during preimplantation development is essential to embryo viability. Recent advances in epigenetic re...
متن کاملTBP Dynamics during Mouse Oocyte Meiotic Maturation and Early Embryo Development
To maintain cell lineage, cells develop a mechanism which can transmit the gene activity information to the daughter cells. In mitosis, TBP (TATA-binding protein), a transcription factor which belongs to TFIID was associated with M phase chromosomes and was proved to be a bookmark for cellular memory. Although previous work showed that TBP was dispensable for mouse oocyte maturation and early e...
