Combined epidermal growth factor and hyaluronic acid supplementation of in vitro maturation medium and its impact on bovine oocyte proteome and competence
(Elsevier, 2015-03-15)The conditions for in vitro oocyte maturation impact on cytoplasmic and nuclear processes in the oocyte. These events are differentially influenced by the nature of the maturation inducer and the presence of intact cumulus ... -
Effect of gaseous atmosphere on different supplementation medium for In Vitro canine oocyte maturation
(Bentham Open, 2014-02)The aim of the present research was to verify the influence of two different atmosphere gases (A: 5%CO2, B: 5%CO2, 5%O2 and 90%N2) on three different maturation media on in vitro maturation (IVM) rates for oocytes from ... -
Exogenous progesterone during in vitro fertilization improves developmental competence of partially cumulus-denuded bovine oocytes
(Elsevier, 2023-11)The progesterone (P4) secreted by cumulus cells has gained attention for its role as a possible physiological inducer of sperm acrosome exocytosis. In mammals, it is generally accepted that fertilization rates of oocytes ... -
Gene expression of growth factor BMP15, GDF9, FGF2 and their receptors in bovine follicular cells = Expresión génica del factor de crecimiento BMP15, GDF9, FGF2 y sus receptores en células foliculares bovinas
(Universidad de Córdoba (Colombia), 2018-12)Introducción. El crecimiento y la maduración folicular implican una serie de transformaciones de diversos componentes del folículo, como el ovocito, las células de la granulosa y de la teca. Varios factores de crecimiento, ... -
Interaction of bovine viral diarrhea virus with bovine cumulus–oocyte complex during IVM: Detection in permissive cells
(Elsevier, 2016-11)Structural changes in the zona pellucida (ZP) of bovine oocytes seem to modulate their interaction with various viral agents, facilitating the viral infection in in vitro production systems. To evaluate the susceptibility ... -
Linoleic acid stimulates neutral lipid accumulation in lipid droplets of maturing bovine oocytes
(Elsevier, 2013-03-01)Linoleic acid (LA) is a polyunsaturated fatty acid present in high concentrations in bovine follicular fluid; when added to maturation culture media, it affects oocyte competence (depending on the type and concentration ... -
Transvaginal ultrasound-guided oocyte retrieval in cattle: state-of-the-art and its impact on the in vitro fertilization embryo production outcome
(Wiley, 2022-12)Transvaginal ultrasound-guided oocyte retrieval (commonly called OPU) and in vitro embryo production (IVP) in cattle has shown significant progress in recent years, in part, as a result of a better understanding of the ...
