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 ...

Heat stress is an important cause of poor development and low survival rates in bovine embryos. Experiments were conducted to test the hypothesis that Bos indicus embryos are more resistant to heat stress than are Bos ...

The aims of this study were to verify the occurrence of single nucleotide polymorphisms (SNPs) in the JY-1 gene and their association with the in vivo and in vitro production of embryos in Holstein donors. The JY-1 protein ...

Total number of cells in cloned embryos is generally lower than that of in vivoderived embryos and in bovines cell allocation at the blastocyst stage, has been observed to be affected in a large proportion of cloned embryos. ...

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 ...

Morphological embryo classification is of great importance for many laboratory techniques, from basic research to the ones applied to assisted reproductive technology. However, the standard classification method for both ...

Scientific research has made possible new hopes for the cure of diverse pathologies provoked by degenerative processes or by direct damage on organs and tissues. One of the fields of study most promising is the use of ...
