Bovine oocyte vitrification: Effect of ethylene glycol concentrations and meiotic stages
(ELSEVIER SCIENCE BV, 2008)
Success in oocyte cryopreservation is limited and several factors as cryoprotectant type or concentration and stage of oocyte meiotic maturation are involved. The aim of the present study was to evaluate the effect of ...
Vitrification of immature feline oocytes with a commercial kit for bovine embryo vitrification
(2013-04-01)
The aim of this study was to evaluate the suitability of a commercial kit for bovine embryo vitrification for cryopreserving cat oocytes and to evaluate comparatively the effects of its use with slow freezing procedure on ...

(2013-04-01)
The aim of this study was to evaluate the suitability of a commercial kit for bovine embryo vitrification for cryopreserving cat oocytes and to evaluate comparatively the effects of its use with slow freezing procedure on ...
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 ...
Effects of the addition of oocyte meiosis-inhibiting drugs on the expression of maturation-promoting factor components and organization of cytoplasmic organelles
(Inst Animal Reproduction Food Research, 2020-03-01)
The present study evaluated the effects of the blockade of meiosis in bovine oocytes by the cyclin-dependent kinase inhibitors roscovitine (ROS) and butyrolactone-I (BL-I) on nuclear maturation and extracellular signal-regulated ...
Thermoprotective effects of IGF-I on bovine germinal vesicle oocytes
(Wiley-Blackwell, 2012-08-01)
Thermoprotective effects of IGF-I on bovine germinal vesicle oocytes
(Wiley-Blackwell, 2012-08-01)
Factors that interfere with oocyte quality for in vitro production of cattle embryos: Effects of different developmental & reproductive stages
(2016-01-01)
The success of IVP is ultimately dependent on the number and quality of the cumulus-oocyte complexes (COC) harvested during the OPU procedure. Several factors appear to be critical to oocyte quality including follicle size, ...
Interaction of bovine viral diarrhea virus with bovine cumulus–oocyte complex during IVM: Detection in permissive cells
(Elsevier, 2016-11)
Structural changes in the zona pellucida (ZP) of bovine oocytes seem to modulate their interaction with various viral agents, facilitating the viral infection in in vitro production systems. To evaluate the susceptibility ...
