Characterisation of the methylation pattern in the intragenic CpG island of the IGF2 gene in Bos taurus indicus cumulus cells during in vitro maturation
(Springer, 2014-01-01)
The aim of this study was to characterise the methylation pattern in a CpG island of the IGF2 gene in cumulus cells from 1-3 mm and a parts per thousand yenaEuro parts per thousand 8.0 mm follicles and to evaluate the ...
The presence of acylated ghrelin during in vitro maturation of bovine oocytes induces cumulus cell DNA damage and apoptosis, and impairs early embryo development
(Cambridge University Press, 2017-09)
The aim of this study was to investigate the effects of acylated ghrelin supplementation during in vitro maturation (IVM) of bovine oocytes. IVM medium was supplemented with 20, 40 or 60 pM acylated ghrelin concentrations. ...
Fibroblast growth factor 17 and bone morphogenetic protein 15 enhance cumulus expansion and improve quality of in vitro-produced embryos in cattle
(Elsevier B.V., 2015-08-01)
Bone morphogenetic protein 15 (BMP15) and members of the fibroblast growth factor (FGF) family are expressed by the oocyte and are involved in the control of cumulus cell function. We tested the hypothesis that FGF17, alone ...
Expresión de la proteína morfogénica ósea 15 (bmp-15) durante la maduración in vitro de ovocitos caninos
(Univ Zulia, Facultad Ciencias Veterinarias, 2016)
This research aims to characterize the pattern of expression of BMP-15 during in vitro maturation of canine oocyte. BMP-15 is a follicular factor related to the oocyte maturation, taking part in cumulus cells expansion and ...
Steroidogenesis in cumulus cells of bovine cumulus-oocyte-complexes matured in vitro with BSA and different concentrations of steroids
(Elsevier B.V., 2002-02-15)
The present in vitro experiments were designed to evaluate the ability of bovine cumulus-oocyte-complexes (COCs)to produce steroids and also to evaluate the modulatory effects of added estradiol, progesterone and testosterone ...

Peculiaridades da coleta de oócitos para produção in vitro de embriões ovinos
(2012)
The expansion of Brazilian sheep rearing promoted the development of new biotechnologies of assisted reproduction in order to increase the production indices concomitantly with accelerated genetic progress. In this context, ...
Direct role of the C-C motif chemokine receptor 2/monocyte chemoattractant protein 1 system in the feline cumulus oocyte complex
(Society for the Study of Reproduction, 2019-04)
Studies were designed to a) evaluate the mRNA expression of the C-C motif chemokine receptor 2 (CCR2) and its chemokine ligands, as well as genes related to periovulatory events, within the cumulus oocyte complex (COC) and ...
