The effects of nicotine on nuclear maturation and meiotic spindle dynamics of bovine oocytes and subsequent embryonic development were investigated. Maturation rates (85%-94%) derived from nicotine treatments at 0.01 to 1.0 mM were similar to the con

Integrins facilitate attachment of cells to the extra-cellular matrix, often binding the arginine-glycine-aspartic acid tri-peptide motif, thus facilitating cell migration, mediating cell-cell adhesion, linking the extracellular matrix (ECM) with cyt

The onset of ribosomal RNA (rRNA) synthesis occurs during the second half of the third cell cycle, that is, at the four-cell stage, in porcine embryos developed in vivo. In the present study the onset of rRNA synthesis was investigated in porcine emb

The effects of cumulus cell removal and centrifugation of maturing bovine oocytes on nuclear maturation and subsequent embryo development after parthenogenetic activation and nuclear transfer were examined. Removal of cumulus cells at 4, 8, and 15 hr

We recently reported the birth of a tammar wallaby produced by intrauterine AI [Paris DBBP et al., Australian Mammal Society Conference, July 2002]. The use of AI has great potential for the conservation of rare and endangered marsupials, but a non-s

Mature porcine oocytes are arrested at metaphase II of meiosis. At fertilization, like all mammalian oocytes they exhibit a low frequency Ca(2+) oscillation lasting several hours. This oscillation is thought to be the signal that triggers resumption

Demecolcine-assisted/induced enucleation has been used in nuclear transfer cloning procedures for many species, yet its mechanism of action remains unclear. Primarily because oocytoplasm protrusion induced by demecolcine is inhibited by the presence

The purpose of these experiments was to determine the effect of electroporation of IP3 into the cytosol of murine secondary oocytes and evaluate any alterations in [Ca2+]i resulting from Ca2+ release from intracellular stores. In addition, we evaluat

These studies were conducted to identify the point during the 4-cell stage at which the porcine embryo begins to control development. Reproductive tracts of gilts were flushed 48 h after the onset of estrus to obtain 1- and 2-cell embryos. To determi
