Embryo aggregation does not improve the development of interspecies somatic cell nuclear transfer embryos in the horse
(Elsevier Science Inc, 2016-09)
The low efficiency of interspecies somatic cell nuclear transfer (iSCNT) makes it necessary to investigate new strategies to improve embryonic developmental competence. Embryo aggregation has been successfully applied to ...
Equine cloning: In vitro and In vivo development of aggregated embryos
(Society For The Study Of Reproduction, 2012-07)
The production of cloned equine embryos remains highly inefficient. Embryo aggregation has not yet been tested in the equine, and it might represent an interesting strategy to improve embryo development. This study evaluated ...
Embryo Aggregation in Pig Improves Cloning Efficiency and Embryo Quality
(Public Library of Science, 2016-02)
In this study, we analyzed the effects of the cloned embryo aggregation on in vitro embryo development and embryo quality by measuring blastocyst diameter and cell number, DNA fragmentation levels and the expression of ...
The aggregation of four reconstructed zygotes is the limit to improve the developmental competence of cloned equine embryos
(Public Library Of Science, 2014-11)
Embryo aggregation has been demonstrated to improve cloning efficiency in mammals. However, since no more than three embryos have been used for aggregation, the effect of using a larger number of cloned zygotes is unknown. ...
Production of chimeric embryos by aggregation of bovine egfp eight-cell stage blastomeres with two-cell fused and asynchronic embryos
(Elsevier Science Inc, 2013-06)
Embryo disaggregation allows the production of two to four identical offspring from a single cow embryo. In addition, embryo complementation has become the technique of choice to demonstrate the totipotency of embryonic ...
Production of bovine chimeric embryos, by aggregation of post-compaction developmental stage half-embryos
(Nottingham University Press, 2010-01-01)
Cheetah interspecific SCNT followed by embryo aggregation improves in vitro development but not pluripotent gene expression
The aim of this study was to evaluate the capacity of domestic cat (Dc, Felis silvestris) oocytes to reprogram the nucleus of cheetah (Ch, Acinonyx jubatus) cells by interspecies SCNT (iSCNT), by using embryo aggregation. ...
State of the art on animal embryonic chimeras
Embryonic chimerism is generally used in basic research and in vivo diagnosis of undifferentiated embryonic stem cells (ESC), mostly using mice embryos, although there have been reports in the literature on using rat, ...
