At the beginning of the 1990s, co-culture of cattle and sheep embryos was the most favoured
method to support embryo development, but the use of this system has hampered progress …

The oviduct is a dynamic organ which facilitates gamete function, fertilization and embryo
development. Secretions of the oviduct, recovered by tissue culture or cannulation …

Low doses of progestogens in regimens for synchronization of estrus result in persistent
follicles (PF) and reduced conception rates in cattle. The effects of PF on recovery of …

The sensitive technique of mRNA phenotyping with the reverse transcription‐polymerase
chain reaction was employed to determine the patterns of gene expression for several …

The techniques of in vitro maturation (IVM) and in vitro fertilization (IVF) of bovine oocytes,
with development of the resulting embryos to advanced preimplantation stages in vitro, have …

The finding that zygotes (one-cell embryos) from several livestock species can be routinely
cultured in relatively simple media to the blastocyst stage questions the nature of the …

BACKGROUND The majority of research aimed at improving embryo development in vitro
has focused on manipulation of the chemical environment, examining details such as …

A 120-kDa oviduct-specific glycoprotein is synthesized and secreted into the oviductal
lumen during estrogen dominance in the human. The objective of this investigation was to …

A co-culture system using a suspension of detached bovine oviducal epithelial cells (BOEC)
has been developed as an effective culture method for supporting the development of …

Published reports indicate that in several mammalian species the oviduct synthesizes and
secretes specific glycoproteins which are components of the luminal fluids at the time of …
