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 ...
Forskolin effect on the cryosurvival of in vitro-produced bovine embryos in the presence or absence of fetal calf serum
(Cambridge University Press, 2014-05-01)
The objective of this study was to assess the viability and cryotolerance of zebu embryos produced in vitro with or without the addition of fetal calf serum (FCS) and forskolin (F). Embryos produced in vivo were used as a ...
Reduction in cytoplasmic lipid content in bovine embryos cultured in vitro with linoleic acid in semi-defined medium is correlated with increases in cryotolerance
(Cambridge University Press, 2015-09-09)
We examined whether culturing embryos with linoleic acid (LA) in semi-defined medium reduces lipid accumulation and improves cryosurvival after vitrification. Embryos were cultured with LA (100 μM) and a semi-defined medium ...
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 ...
Update and overview on assisted reproductive technologies (ARTs) in Brazil
(2016-01-01)
The impressive increase in the use of assisted reproductive technologies (ARTs), especially in cattle, during the last few years in Brazil is well known worldwide. In 2015, there were over 13.7 million artificial inseminations ...
Effects of different cryopreservation methods on post-thaw culture conditions of in vitro produced bovine embryos
(Cambridge Univ PressNew York, 2012-05)
The aim of this work was to evaluate the effect of cryopreservation protocols on subsequent development of in vitro produced bovine embryos under different culture conditions. Expanded in vitro produced blastocysts (n = ...
Recent progress in bovine In vitro‐derived embryo cryotolerance: impact of In vitro culture systems, advances in cryopreservation and future considerations
(Wiley, 2020-03-07)
Cryopreservation of in vitro‐derived bovine embryos is a crucial step for the widespread reproduction and conservation of valuable high merit animals. Given the current popularity of bovine in vitro embryo production (IVP), ...
