Recreating the Follicular Environment: A Customized Approach for In Vitro Culture of Bovine Oocytes Based on the Origin and Differentiation State
(2021-01-01)
The mammalian ovary is a large source of oocytes organized into follicles at various stages of folliculogenesis. However, only a limited number of them can be used for in vitro embryo production (IVEP), while most have yet ...
The effect of serum on in vitro maturation, in vitro fertilization and steroidogenesis of bovine oocytes co-cultured with granulosa cells.
(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 ...

Follicular environment and oocyte maturation: roles of local peptides and steroids
(Brazilian Coll Animal Reproduction, 2017-07-01)
A large amount of data on the mechanisms regulating cumulus-oocyte maturation in mammals has been generated in the last 20 years. It has been made clear that oocyte-secreted factors play a central role in the control of ...
Bovine dominant follicular fluid promotes the in vitro development of goat preantral follicles
(CSIRO Publishing, 2012-01-01)
The aim of this study was to evaluate the effect of follicular fluid collected from bovine dominant follicles (bFF) on the in vitro development of goat preantral follicles and determine the best time to add this supplement ...

Oocyte competence: importance and determinant factors in vivo and in vitroCompetência oocitária: Importância e fatores determinantes in vivo e in vitro
(2019-01-01)
Reproductive biotechnology promoted beef cattle production growth in the global agribusiness scenario due to the reduction of generation interval, accelerated genetic gain and productivity enhancement. In this context, ...
Effects of FGF10 on bovine oocyte meiosis progression, apoptosis, embryo development and relative abundance of developmentally important genes in vitro
(Wiley-Blackwell, 2015-02-01)
Contents Fibroblast growth factor (FGF10) acts at the cumulus oocyte complex, increasing the expression of cumulus cell expansion-related genes and oocyte competency genes. We tested the hypothesis that addition of FGF10 ...
Molecular and cellular effects of insulin-like growth factor-1 and LongR3-IGF-1 on in vitro maturation of bovine oocytes: comparative study
(Churchill Livingstone, 2020-12-01)
Addition effects of insulin-like growth factor-1 (IGF-1) and its synthetic analogue insulin-like growth factor-1 recombinant-3 (LongR3-IGF-1) after in vitro maturation (IVM) of cattle cumulus-oocyte complexes (COCs) were ...
