Determination of Oocyte-Manipulation, Zygote-Manipulation, and Genome-Reprogramming Effects on the Transcriptomes of Bovine Blastocysts

open access: yesFrontiers in Genetics, 2018
Somatic cell nuclear transfer (scNT) embryos suffer from damage caused by micro-operation (manipulation) and inefficient genome reprograming that hinder their normal development at different levels and in distinct ways.

Comparative Analysis of Nuclear Transfer Embryo Derived Mouse Embryonic Stem Cells. Part II: Gene regulation [PDF]

open access: yes, 2012
In a mouse model nuclear transfer embryo-derived embryonic stem cell lines (ntESCs) of various genetic backgrounds and donor cell types were compared with reference ESCs and analyzed comprehensively at molecular level as a second part of a larger study ...

One nucleon transfer operator and nuclear supersymmetry [PDF]

open access: yes, 2005
The appropriate use of the interacting boson-fermion model one nucleon transfer operator in connection with nuclear supersymmetries is discussed. We emphasize that care must be taken in using the same coupling order, either l-s or s-l, in

Nuclear transfer in rodents

open access: yesThe Journal of Physiology, 2003
Cloning is the asexual reproduction of an individual, such that the offspring have an essentially identical nuclear genome. Nuclear transfer and cloning have been achieved in a number of species, namely sheep, cows, goats, rabbits, cats and mice, but have been largely unsuccessful, so far, in dogs, primates and rats. Clearly, contributory factors which

The mRNA expression of brain-derived neurotrophic factor in oocytes and embryos and its effects on the development of early embryos in cattle

open access: yesAnimal, 2008
The aims of the study were to measure the mRNA expression of brain-derived neurotrophic factor (BDNF) in bovine oocytes and early embryos derived from in vitro fertilization (IVF), parthenogenetic activation (PA) and nuclear transfer (NT), and to ...

Efeito do número da passagem e do gênero das células doadoras de núcleo no desenvolvimento de bovinos produzidos por transferência nuclear Effect of culture time and gender of nuclei donor cells on bovine development produced by nuclear transfer

open access: yesRevista Brasileira de Zootecnia, 2010
Objetivou-se com este trabalho avaliar o efeito do número da passagem e do sexo das células doadoras de núcleo no desenvolvimento embrionário e fetal após transferência nuclear.

Characterization of Ku70(2)-NLS as bipartite nuclear localization sequence for non-viral gene delivery. [PDF]

open access: yes, 2012
Several barriers have to be overcome in order to achieve gene expression in target cells, e.g. cellular uptake, endosomal release and translocation to the nucleus.

Various nuclear reprogramming systems using egg and oocyte materials

open access: yesThe Journal of Reproduction and Development, 2019
Maternal factors stored in eggs and oocytes are necessary for reprogramming sperm for embryonic development. This reprogramming activity of maternal factors also works towards somatic cells, including terminally differentiated cells.

Aberrant imprinting in mouse trophoblast stem cells established from somatic cell nuclear transfer-derived embryos

open access: yesEpigenetics, 2018
Although phenotypic abnormalities frequently appear in the placenta following somatic cell nuclear transfer (SCNT), mouse trophoblast stem cells (TSCs) established from SCNT embryos reportedly show no distinct abnormalities compared with those derived ...

Comparison of in vitro Neuronal Differentiation Capacity Between Mouse Epiblast Stem Cells Derived From Nuclear Transfer and Naturally Fertilized Embryos

open access: yesFrontiers in Molecular Neuroscience, 2018
Somatic cell nuclear transfer (SCNT) can give rise to fertile adults, but the successful perinatal and postnatal developmental rates are inefficient, including delayed developmental behaviors, and respiratory failure.
