Background: Because of the protection of surplus embryos, Cryopreservation is usually used in ART. It is not clear, the vitrified-warmed embryos that have normal morphology, be normal in genetic level, too. DNA methylation of gene regulatory regions can causes inhibition of gene expression. We study effect of vitrification method of cryopreservation on DNA methylation and gene expression level ...
Accurate identification of abnormalities in the mouse embryo depends not only on comparisons with appropriate, developmental stage-matched controls, but also on an appreciation of the range of anatomical variation that can be expected during normal development. Here we present a morphological, topological and metric analysis of the heart and arteries of mouse embryos harvested on embryonic day ...
Functional Analysis of Nocturnin, a Circadian Deadenylase, at Maternal-to-zygotic Transition in Mice
Degradation of maternally stored mRNAs after fertilization is an essential process for mammalian embryogenesis. Maternal mRNA degradation depending on deadenylases in mammalian early embryos has been mostly speculated, rather than directly demonstrated. Previously, we found that gene expression of nocturnin, which functions as a circadian clock-controlled deadenylase in mammalian cells, was cle...
Background: The assisted reproductive techniques (ARTs) such as in vitro fertilization, embryo transfer and cryopreservation of gametes have considerably contributed to the development of biomedical sciences in addition to improved breeding in domestic animals and infertility treatment in humans. However, ARTs used in canine species have strictly limited utility when compared with other mammali...
