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
(2013-01-15)
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 ...
Short communication: JY-1 gene variants and embryo production in Holstein cows
(2021-02-01)
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 ...
Factors affecting pregnancy rates for goat embryos recovered and transferred by transcervical route
(Elsevier B.V., 2020-11-01)
This study evaluated the factors affecting non-surgical embryo transfer (NSET) efficiency in goats. Donor goats (n = 10) were superovulated, mated and embryos were collected by non-surgical embryo recovery 7 d after estrous ...
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)
(2011-05-01)
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)
(SPRINGER, 2008)
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
(2011-03-01)
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 ...
Which Factors Affect Pregnancy Until Calving and Pregnancy Loss in Buffalo Recipients of in vitro Produced Embryos?
(Frontiers Media Sa, 2020-12-02)
In vitro embryo production and embryo transfer (ET) in buffaloes has been developed for decades. However, most studies are focused on the donor or laboratory improvements, and there is a lack of reports regarding the ...
