Interação YAP1-TEAD regula a cascata de sinalização do EGF em células do cumulus em bovinos
(Universidade Federal de Santa MariaBrasilMedicina VeterináriaUFSMPrograma de Pós-Graduação em Medicina VeterináriaCentro de Ciências Rurais, 2020-02-07)
The mechanism of cumulus cell (CC) expansion and ovulation in vivo is triggered by LH surge in granulosa cells and CC, which culminating in a series of paracrine and autocrine communications between these ovarian cells. ...
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 ...
O sistema peptídeos natriuréticos está presente no complexo cumulus-oócito e regula o reinício da meiose em bovinos
(Universidade Federal de Santa MariaBRMedicina VeterináriaUFSMPrograma de Pós-Graduação em Medicina Veterinária, 2013-02-20)
The process of meiotic resumption in oocytes, arrested since fetal life, and the
expansion of compact layers of cumulus cells is triggered by intrafollicular mediators
stimulated by LH. These events are extremely complex. ...
The importance of manganese in the cytoplasmic maturation of cattle oocytes: blastocyst production improvement regardless of cumulus cells presence during in vitro maturation
(Cambridge University Press, 2016-02)
Adequate dietary intake of manganese (Mn) is required for normal reproductive performance in cattle. This study was carried out to investigate the effect of Mn during in vitro maturation of bovine cumulus–oocyte complexes ...
Time course of the meiotic arrest in sheep cumulus-oocyte complexes treated with roscovitine
(Cambridge University Press, 2015)
Temporary meiosis arrest with cyclin-dependent kinases inhibitors has been proposed in order to improve the quality of in vitro matured oocytes. In sheep, however, this phenomenon has been rarely investigated. Therefore, ...
Effects of fibroblast growth factor 8 on cumulus expansion and nuclear maturation in bovine cumulus-oocyte complexes
(CSIRO Publishing, 2013-01-01)
GDF-9 and BMP-15 mRNA levels in canine cumulus cells related to cumulus expansion and the maturation process
(MDPI, 2020)
Simple Summary The knowledge of physiological events associated with canine reproduction involving oocyte developmental potential is essential to increase the success of reproductive biotechnologies in this species. In ...
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 ...
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 ...
The importance of having zinc during in vitro maturation of cattle Cumulus–Oocyte complex: role of Cumulus cells
(Wiley VCH Verlag, 2014-10)
The aim of this study was to investigate the influence of zinc (Zn) on the health of cumulus–oocyte complex (COC) during in vitro maturation (IVM). Experiments were designed to evaluate the effect of Zn added to IVM medium ...
