The use of transmission electron microscopy and oocyte transfer to evaluate in vitro maturation of equine oocytes in different culture conditions
(Elsevier B.V., 2006-04-01)
The current study evaluates the ability of equine oocytes matured in different conditions to undergo nuclear and cytoplasmic maturation.. After oocyte transfer, embryonic development was diagnosed at 1.5 and 90 days of ...

Combined EGF and Hyaluronic acid supplementation of in vitro maturation medium and its impact on bovine oocyte proteome and competence
(Elsevier Science Inc, 2015-03)
The conditions for in vitro oocyte maturation impact on cytoplasmic and nuclear processes in the oocyte. These events are differentially influenced by the nature of the maturation inducer as well as by the presence of ...
Human sperm chemotaxis: Both the oocyte and its surrounding cumulus cells secrete sperm chemoattractants
(Oxford University Press, 2005-03)
Background: Human sperm chemotaxis to pre-ovulatory follicular fluid is well established in vitro. However, it is not known whether the female's oocyte-cumulus complex secretes sperm chemoattractants subsequent to ovulation ...
Efeito de um meio condicionado por células do Cumulus oophorus de bovinos na maturação e no potencial de desenvolvimento embrionário in vitro de oócitos desnudos
(Universidade Federal de Minas GeraisUFMG, 2017-08-31)
One of the challenges of reproductive biology and medicine is to understand the nature of the molecular and cellular processes that control oocyte developmental competence. This competence, acquired through maturation, a ...
Meiotic arrest of sheep oocytes using roscovitine under different medium compositions
(Elsevier B.V., 2015-05-01)
Attempts to maintain the meiotic arrest under suitable culture conditions have been performed in order to improve the quality of oocytes in vitro matured. So, our study aimed to evaluate the potential of roscovitine, an ...
Zinc supports transcription and improves meiotic competence of growing bovine oocytes
(2020-05-01)
In the last years, many studies focused on the understanding of the possible role of zinc in the control of mammalian oogenesis, mainly on oocyte maturation and fertilization. However, little is known about the role of ...
Conditions affecting protein synthesis in amphibian oocytes
(1976)
The endogenous protein synthesis of Xenopus laevis and Calyptocephalella caudiverbera oocytes was studied by measuring the incorporation into acid-precipitable material of radioactive amino acids placed in the extracellular ...
Combined epidermal growth factor and hyaluronic acid supplementation of in vitro maturation medium and its impact on bovine oocyte proteome and competence
(Elsevier, 2015-03-15)
The conditions for in vitro oocyte maturation impact on cytoplasmic and nuclear processes in the oocyte. These events are differentially influenced by the nature of the maturation inducer and the presence of intact cumulus ...
