Fibroblast growth factor 2 regulates cumulus differentiation under the control of the oocyte
(Springer, 2019-05-01)
PurposeWe first assessed regulation of FGF2 expression in cumulus cells by FSH and oocyte-secreted factors during in vitro maturation (IVM). Then, we tested the hypothesis that FGF2 regulates meiotic progression, cumulus ...
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 ...

Heat stress induced alteration in bovine oocytes: functional and cellular aspects
(2012)
High environmental temperatures observed during the hot months of the year reduce fertility in lactating dairy cows. Summer heat stress depression in fertility is a multifactorial problem that affects physiological and ...
Paracrine and autocrine factors in the differentiation of the cumulus-oocyte complex
(Brazilian Coll Animal Reproduction, 2012-07-01)
A better understanding of the paracrine and autocrine regulatory loops within the cumulus-oocyte complex (COC) is fundamental for the improvement of in vitro maturation (IVM) outcomes in humans and domestic species. This ...
Follicular somatic cell factors and follicle development
(CSIRO Publishing, 2011-01-01)
Considerable attention is currently paid to oocyte-derived secreted factors that act upon cumulus and granulosa cells. Also important for follicle development are somatic cell-derived secreted factors. This is illustrated ...

Regulação da expressão de fatores secretados pelo oócito (FSOs) e seus receptores durante a maturação in vitro (MIV) bovina e ações no controle da expressão de cumulus
(Universidade Estadual Paulista (Unesp), 2011-02-06)
O oócito participa ativamente dos mecanismos reguladores da maturação do complexo cumulus-oócito (COC) via secreção de fatores parácrinos. A proteína morfogênica óssea 15 (BMP15) e o fator de crescimento e diferenciação 9 ...
