Methods for assessing the quality of mammalian embryos: How far we are from the gold standard?
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 ...
Effects of heat stress on development, quality and survival of Bos indicus and Bos taurus embryos produced in vitro
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 ...
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 ...
Effects of FGF10 on oocyte maturation, quality and capacity to become an embryo
Advances in the development of a noninvasive embryo model for the evaluation of the quality of cloned embryos subjected to different treatments
(Pontificia Universidad Católica de Valparaíso, 2008)
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 ...
Effects of timing of induced luteolysis in embryo donor mares on reproductive performance and pregnancy rate in recipient mares
(Elsevier B.V., 2011-04-01)
The objective was to evaluate the effects of giving prostaglandin F(2 alpha) (PGF) to donor mares 48 h prior to embryo collection. Non-lactating donor mares (n = 20 estrous cycles in 10 mares), ranging from 2.5 to 10 y of ...
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 ...
ADVANCES IN THE DEVELOPMENT OF A NONINVASIVE EMBRYO MODEL FOR THE EVALUATION OF THE QUALITY OF CLONED EMBRYOS SUBJECTED TO DIFFERENT TREATMENTS
(UNIV CATOLICA DE VALPARAISO, 2008)
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. ...
