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 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 ...
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 ...
Effect of vitrification on viability and chromosome abnormalities in 8-cell mouse embryos at various storage durations
(Sociedad de Biología de Chile, 2007)
Valor preditivo do potencial de implantação embrionário pela análise do perfil químico de meios de cultivo por espectrometria de massas (ESI-Q-ToF)
Objective: This case-control study analyzed mass spectrometry fingerprinting patterns of culture media samples used for embryo culture to predict embryo implantation. Methods: The culture medium harvested after embryo ...
Changes in soluble carbohydrates and starch amounts during somatic and zygotic embryogenesis of Acca sellowiana (Myrtaceae)
Comparative analysis of zygotic and somatic embryogenesis of Acca sellowiana showed higher amounts of sucrose, fructose, raffinose, and myo-inositol in zygotic embryos at different developmental stages than in corresponding ...
Embryos refrozen-thawed by vitrification lead to live births: Case report
Objective: To describe two successful cases of utilizing refrozen blastocysts by vitrification derived from supernumerary embryos. Design: Case report. Setting: Private fertility clinic. Subjects: Two infertility couple. ...
A simple vitrification technique for sheep and goat embryo cryopreservation
(Elsevier Science, 2011-01)
The aim of this study was to evaluate pregnancy and embryo survival rate of vitrified in vivo produced Merino sheep and Criolla goat (morulae and blastocysts) embryos, using the plastic tips of micropipettes, as containers ...
Laser-assisted hatching of cryopreserved-thawed embryos by thinning one quarter of the zona
Laser-assisted hatching is little documented in the literature regarding its efficacy in cryopreserved-thawed (CT) embryo transfer cycles. The aim of the present study was to evaluate in a randomized manner the efficacy ...
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)
