Day of collection affects the number of embryos recovery on ewes
Cryopreservation of equine embryos with glycerol plus sucrose and glycerol plus 1,2-propanediol.
Six or 7-day-old equine embryos were divided into 4 groups; Group 1, n = 15, Day 7 embryos destined for immediate transfer; Group 2, n = 15, Day 6 embryos destined for deep-freezing with glycerol plus sucrose as cryoprotectant; ...

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
(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. ...
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 ...
Morphology, sex ratio and gene expression of Day 14 in vivo and in vitro bovine embryos
The present study was designed to compare Day 14 bovine embryos that were produced entirely in vitro using the post-hatching development (PHD) system with in vivo-derived embryos without or with transient PHD culture from ...
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 ...
