Efeito das células do cumulus e cisteamina durante o cultivo de maturação in vitro de oócitos bovinos sobre a maturação nuclear e aquisição da competência para desenvolvimento embrionário
(Universidade Federal de Minas Gerais (UFMG), Escola de Veterinária, 2012-04-01)
Complexos cumulus-oócito (COC), oócitos desnudos (DO) e do cocultivados com células do cumulus em suspensão (DO+CC) foram maturados in vitro (MIV) na presença ou ausência de cisteamina (50mM). Observou-se efeito benéfico ...

Granulocyte-macrophage colony stimulating factor (GM-CSF) enhances cumulus cell expansion in bovine oocytes
(BIOMED CENTRAL LTD, 2013-06-24)
Background: The objectives of the study were to characterize the expression of the α- and β-subunits of
granulocyte-macrophage colony stimulating factor (GM-CSF) receptor in bovine cumulus cells and oocytes and to
determine ...
Stromal-derived factor 1 directly promotes genes expressed within the ovulatory cascade in feline cumulus oocyte complexes
(Springer/Plenum Publishers, 2018-03)
Purpose We hypothesized that the chemokine SDF1/CXCR4 system was present in feline cumulus-oocyte complexes (COCs) and that COCs cultured with SDF1 would directly upregulate gene expression in the ovulatory cascade. Methods ...
The antioxidant dimethylthiourea improves in vitro fertilization efficiency and decreases cumulus cells apoptosis in pigs
(Csiro Publishing, 2019-09)
Abattoir ovaries, which are the main source of oocytes for reproductive biotechnologies, arrive at the laboratory under ischaemic conditions. Reoxygenation generates reactive oxygen species (ROS) in ischaemic tissues, which ...
Influência da temperatura de fecundação In vitro e das células do Cumulus oophorus sobre a taxa de polispermia e desenvolvimento embrionário
(Goiânia, 2010)
O objetivo deste trabalho foi avaliar o efeito da temperatura (37 ou 38,5°C) de fecundação in vitro (FIV) e da retirada das células do cumulus oophorus após a FIV ou após doze horas de cultivo embrionário (CIV), nos índices ...

Expression of growth differentiation factor 9 (GDF-9) during invitro maturation in canine oocytes
(2013)
The aim of this study was to characterize in canine oocytes and cumulus cells the dynamic expression of growth differentiation factor 9 (GDF-9) in relation to meiotic development and cumulus expansion throughout invitro ...
