Nuclear transfer (NT) is an inefficient but invaluable tool. This study examines abnormalities associated with NT porcine embryos at days 10, 12, and 14. Methods: 4 experimental groups were examined: non-pregnant, in vivo ...

Reproductive technologies such as in vitro fertilization, intracytoplasmic sperm injection, parthenogenetic activation, and somatic cell nuclear transfer are powerful procedures in the production of animals for agriculture, ...

It was the objective of these experiments to more fully characterize the biochemical and developmental responses of in vitro-produced preimplantation stage porcine embryos to elevated temperatures. In vitro fertilized (IVF) ...

Identification of transcripts present at key development stages in preimplantation embryos is critical for a better understanding of early embryogenesis. To that end, we characterized the relative abundance of multiple ...

In most mammals, female reproductive tracts undergo extensive tissue remodeling throughout the estrous cycle and during pregnancy that arise in response to an array of endocrine, paracrine, and autocrine signals. These ...
