First proteomic analysis of diestrus and anestrus canine oocytes at the germinal vesicle reveals candidate proteins involved in oocyte meiotic competence
(2019-12-01)
In domestic dogs, oocyte maturation rates are low and the percentage of oocytes that remain in the stage of germinal vesicle (GV) regardless of culture conditions is high. The present study was conducted to characterize ...
In Vitro maturation of fully grown mouse antral follicles in the presence of 1 nM 2-Hydroxyestradiol improves Oocytes’ developmental competence
(Springer, 2020)
Cathecolestrogens are estradiol metabolites produced during folliculogenesis in the mammalian ovary. 2-Hydroxyestradiol (2-OHE2) is one of the most abundant although its role remains unknown. The aim of this study is to ...
Delaying meiotic resumption during transportation of bovine cumulus-oocyte complexes: Effects on development, apoptosis and caspases activity of in vitro-produced embryos
(2017-12-01)
This study examined the effects of meiosis inhibition during bovine oocyte transportation on developmental competence and quality of produced embryos. The transportation medium was supplemented with: 100 μM butyrolactone ...
Influence of hepes on in vitro maturation of canine oocytes in different stages of the estrous cycleInfluência do hepes na maturação in vitro de oócitos caninos obtidos de cadelas em diestro e anestro
(2019-01-01)
Unlike other domestic animals, in vitro maturation (IVM) of canine oocytes still has limited success. The aim of this study was to evaluate the effect of HEPES on the in vitro maturation of dog oocytes in anestrus and ...
Meiotic inhibition of bovine oocytes in medium supplemented with a serum replacer and hormones: effects on meiosis progression and developmental capacity
(Cambridge University Press, 2011-05-01)
Aiming to improve the developmental competence of bovine oocytes during meiotic block, this study evaluated the effects of a serum replacer (Knockout SR(R)) and hormones (gonadotropins and estradiol) supplementation of ...

(Cambridge University Press, 2011-05-01)
Aiming to improve the developmental competence of bovine oocytes during meiotic block, this study evaluated the effects of a serum replacer (Knockout SR(R)) and hormones (gonadotropins and estradiol) supplementation of ...
Zinc supports transcription and improves meiotic competence of growing bovine oocytes
(2020-05-01)
In the last years, many studies focused on the understanding of the possible role of zinc in the control of mammalian oogenesis, mainly on oocyte maturation and fertilization. However, little is known about the role of ...
Effect of collection-maturation interval time and pregnancy status of donor mares on oocyte developmental competence in horse cloning
(American Society of Animal Science, 2013-11-24)
The current limitations for obtaining ovaries from slaughterhouses and the low efficiency of in vivo follicular aspiration necessitate a complete understanding of the variables that affect oocyte developmental competence ...
