The survival of the preimplantation mammalian embryo depends not only on providing the
proper conditions for normal development but also on acquiring the mechanisms by which …

Contents Cryopreservation of in vitro‐derived bovine embryos is a crucial step for the
widespread reproduction and conservation of valuable high‐merit animals. Given the …

Success of in vitro maturation (IVM) and production of bovine embryos as related to aspects
of follicle source and oocyte size were evaluated. First, it was determined that bovine …

The classical concept of sex determination in mammals is that a Y chromosomal gene
controls the development of the indifferent gonad into a testis. Subsequent divergence of …

The objectives were 1) to investigate the effects of oocyte maturation in serum-free and
amino acid-supplemented defined media on oocyte transcript levels, blastocyst cell number …

The metabolism of radiolabelled glucose and glutamine was measured in individual cattle
embryos produced by in vitro maturation and fertilization of oocytes, and culture with bovine …

Bovine oocytes are damaged when chilled to temperatures near 0° C. We have determined
the temperatures at which this injury occurs, as well as its kinetics and the functional …

Cell death occurs during early development in vivo and in vitro, although little is known
about the mechanism of blastomere death and the relation to embryonic loss. Apoptosis …

The process of development depends on a number of signaling systems that regulates the
progressive sequence of developmental events. Infertility and neurodevelopmental …

The effect of conditioned medium (CM) or microvesicles (MVs), secreted by multicellular
spheroids of oviductal cells, and the involvement of some microRNAs (miRNAs) were …
