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 ...
Abandoned frozen embryos in argentina: A committee opinion
(Sociedade Brasileira de Reprodução Assistida, 2019-04)
Argentina, like many other countries in the region, faces the dilemma of what to do with the increasing accumulation of frozen embryos, which are often abandoned. This report aims to address the issue of abandoned frozen ...

Vitrified embryo transfer in Merino sheep under extensive conditions
(Colégio Brasileiro de Reproducao Animal, 2019-06)
The aim was to evaluate pregnancy success after transfer of embryos vitrified in micropipette tips in Merino sheep under extensive conditions. A second objective was to evaluate the influence of embryo stage in such pregnancy ...
Stratification temperature affects the In Vitro germination of immature Prunus embryos
(ISHS, 2004)
The rapid multiplication of clonal plants is desirable to shorten crossing programs in fruit tree breeding. In vitro stratification and germination allowed us to shorten the time and to improve the germination rates by ...
Oral misoprostol does not hasten oviductal transport of day-5 horse embryos
(Elsevier Science, 2020-12)
In horses, prostaglandin E2 (PGE2) is produced by embryos around Day 5 post-ovulation; PGE2 functions directly at the oviduct promoting embryo transport into the uterus. Non-surgical collection of horse embryos for ...

The egg capsules, eggs and embryos of the muricid gastropod Coronium coronatum are described for the first time. Capsules are sessile, bulliform, semi-circular, with a plug in the dorsal center. Sutures split the capsule ...
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), ...
Rhinella fernandezae (Bella Vista toad): Eggs and Embryos Predation by Leeches
(Society for the Study of Amphibians and Reptiles, 2018-07)
Predation of eggs and embryos is one of the reasons of early mortality in anurans, and it is known that embryos of several amphibian species can accelerate its hatching, as a mechanism to reduce predation risk. Several ...
