Developmental Competence and Pluripotency Gene Expression of Cattle Cloned Embryos Derived from Donor Cells Treated with 5-aza-2'-deoxycytidine [PDF]

open access: yesInternational Journal of Fertility and Sterility, 2011
Background Reconstructed embryos from terminally differentiated somatic cells have revealed high levels of genomic methylation which results in inappropriate expression patterns of imprinted and non-imprinted genes.

Nuclear Transfer using Human CD59 and IL-18BP Double Transgenic Fetal Fibroblasts in Miniature Pigs

open access: yesJournal of Animal Reproduction and Biotechnology, 2016
Xenotransplantation involves multiple steps of immune rejection. The present study was designed to produce nuclear transfer embryos, prior to the production of transgenic pigs, using fibroblasts carrying transgenes human complement regulatory protein ...

Nuclear Transfer to Eggs and Oocytes [PDF]

open access: yesCold Spring Harbor Perspectives in Biology, 2011
We review experiments in which somatic cell nuclei are transplanted singly to enucleated eggs (metaphase II) in amphibia and mammals and as multiple nuclei to the germinal vesicle of amphibian oocytes (prophase I). These experiments have shown the totipotency of some somatic cell nuclei, as well as switches in cell type and changes in gene expression ...

Nanostructured Coatings Based on Langmuir–Blodgett Films of Perfluorodecanoic Acid for Flexible Sensors for the Analysis of Lead Ions in Water

open access: yesПриборы и методы измерений
As a result of anthropogenic activities, the environment is polluted by heavy metals. The most important task is to find methods to control their content in water.

Cloning animals by somatic cell nuclear transfer – biological factors

open access: yesReproductive Biology and Endocrinology, 2003
Cloning by nuclear transfer using mammalian somatic cells has enormous potential application. However, somatic cloning has been inefficient in all species in which live clones have been produced.

Functional consequences of mitochondrial mismatch in reconstituted embryos and offspring

open access: yesThe Journal of Reproduction and Development, 2019
Animal cloning technology has been developed to produce progenies genetically identical to a given donor cell. However, in nuclear transfer protocols, the recipient oocytes contribute a heritable mitochondrial genomic (mtDNA) background to the progeny ...

Comparative study of constitutive relations implemented in RELAP5 and TRACE – Part II: Wall boiling heat transfer

open access: yesNuclear Engineering and Technology, 2022
Nuclear thermal-hydraulic system analysis codes have been developed to comprehensively model nuclear reactor systems to evaluate the safety of a nuclear reactor system.

Effect of the Compaction and the Size of DNA on the Nuclear Transfer Efficiency after Microinjection in Synchronized Cells

open access: yesPharmaceutics, 2015
The nuclear transfer process is one of the critical rate-limiting processes in transgene expression. In the present study, we report on the effect of compaction and the size of the DNA molecule on nuclear transfer efficiency by microinjection.

The Influence of Oviductal and Uterine Fluid Supplementation on the In Vitro Development and Quality of Cloned Sheep Embryos

open access: yesAnimals
Somatic cell nuclear transfer (SCNT) has great potential for the replication of high-commercial-value animals, threatened wild species for conservation purposes, and transgenic animals for biomedical purposes.
