Effect of Hormonal Supplementation Periods and In Vitro Maturation Media on Developmental Competence of Pig Oocytes
(UNIV FED RIO GRANDE DO SUL, 2010)
Background: The oocyte ability to undergo successful fertilization, cleavage and embryonic development depends on meiotic maturation and developmental competence acquisition. In vitro maturation (IVM) protocols currently ...
In vitro Maturation of Oocytes from Santa Ines Ewes Subjected to Consecutive Sessions of Follicular Aspiration by Laparoscopy
(Wiley-Blackwell, 2014-04-01)
Contents The success of embryo production in vitro depends upon the use of an efficient oocyte retrieval technique, and the best results have been obtained by laparoscopic aspiration. The aim of this study was to evaluate ...
Feed restriction and insulin-like growth factor-I (IGF-I) affect the oocyte maturation in matrinxã Brycon amazonicus
(2017-01-01)
Summary The feeding and nutrition of breeders are crucial aspects in the reproductive process. During the maturation period, metabolic changes occur aiming at mobilizing energy for growth and follicular development. The ...
Live imaging of cortical granule exocytosis reveals that in vitro matured mouse oocytes are not fully competent to secret their content
(Company of Biologists, 2018-10)
Oocyte in vitro maturation does not entirely support all the nuclear and cytoplasmic changes that occur physiologically and it is poorly understood whether in vitro maturation affects the competence of cortical granules ...
Dynamics of steroid‐induced oocyte maturation in three amphibian species: Mathematical modeling and simulation
(John Wiley & Sons Inc, 2018-12)
Oocyte maturation in vertebrates involves morphological, biochemical, and functional changes through which meiosis, previously arrested in Profase I, is resumed. Within these changes, germinal vesicle breakdown (GVBD) ...
THE EFFECT OF SERUM ON IN-VITRO MATURATION, IN-VITRO FERTILIZATION AND STEROIDOGENESIS OF BOVINE OOCYTES COCULTURED WITH GRANULOSA-CELLS
(Associação Brasileira de Divulgação Científica (ABRADIC), 1995-02-01)
The influence of fetal calf serum alone (FCS) or associated with proestrous (FCS+PCS), estrous (FCS+ECS) or metaestrous (FCS+MCS) cow serum added to the culture medium and of the steroids produced by co-cultured granulosa ...

Dataset on lipid profile of bovine oocytes exposed to Lα-phosphatidylcholine during in vitro maturation investigated by MALDI mass spectrometry and gas chromatography-flame ionization detection
(2017-08-01)
Data presented in this article are related with the research article entitled “Effect of soybean phosphatidylcholine on lipid profile of bovine oocytes matured in vitro” [1]. This article describes the differences in the ...
