Paternal effect does not affect in vitro embryo morphokinetics but modulates molecular profile
(2022-01-15)
The use of different sires influences in vitro embryo production (IVP) outcome. Paternal effects are observed from the first cleavages until after embryonic genome activation (EGA). Little is known about the mechanisms ...
Producción de embriones in vitro a partir de óvulos y ovarios de papaya (Carica papaya L.)In vitro production of papaya (Carica papaya L.) embryos from ovules and ovaries
(Universidad de Costa Rica, 1998)
Se estudió la posibilidad de obtener plantas a partir del cultivo de óvulos y ovarios provenientes de flores no fecundadas de C. papaya . Para esto se evaluó la influencia del tamaño del ovario y del efecto de diferentes ...
Comparison of embryo yield and pregnancy rate between in vivo and in vitro methods in the same Nelore (Bos indicus) donor cows
(Elsevier B.V., 2009-03-01)
To investigate why the preferred means to produce bovine embryos in Brazil has changed from in vivo to in vitro, we compared these two approaches in the same Nelore cows (n = 30) and assessed total embryo production and ...

In vitro production of bovine embryos using Sigma antioxidant supplement®, α-tocopherol and L-ascorbic acid
(2010)
This study tested the effect of Sigma antioxidant supplement®, α-tocopherol (vitamin E) and L-ascorbic acid (vitamin C) in the culture medium of bovine embryos. In experiment 1, in vitro produced bovine zygotes were cultured ...
The effects of crocetin supplementation on the blastocyst outcome, transcriptomic and metabolic profile of in vitro produced bovine embryos
(2019-01-01)
The earliest stages of embryo development are deeply influenced by reactive oxygen species (ROS), byproducts of the mitochondrial oxygen metabolism that play a key role as messengers in normal cell signal transduction and ...
Influence of bovine serum albumin and fetal bovine serum supplementation during in vitro maturation on lipid and mitochondrial behaviour in oocytes and lipid accumulation in bovine embryos
(2016-01-01)
Proper oocyte maturation is crucial for subsequent embryo development; however, oocyte mitochondrial and lipid-droplet behaviour are still poorly understood. Although excessive lipid accumulation during in vitro production ...
Produção in vitro de embriões bovinos do sexo feminino por sexagem de espermatozóides em gradiente de densidade, modificações na maturação e na fecundação in vitro
(Universidade Estadual Paulista (Unesp), 2012-03-02)
Foram estudadas modificações feitas no tempo de maturação in vitro de oócitos bovinos, incubação dos espermatozóides e separação dos mesmos por gradiente de densidade de PercollTM, bem como a associação dessas técnicas ...
PRODUCTION of RECONSTRUCTED IN VITRO PRODUCED BOVINE EMBRYOS BY INNER CELL MASS and TROPHECTODERM AGGREGATION IN VITRO
