Mammalian preimplantation embryonic development is a complex, conserved, and well-
orchestrated process involving dynamic molecular and structural changes. Understanding …

Several growth factors have been identified as local regulators of follicle development and
ovulation. Fibroblast growth factor (FGF) family members are potent mitogens and are …

In vitro embryo production systems are limited by their inability to consistently produce
embryos with the competency to develop to the blastocyst stage, survive cryopreservation …

There is species divergence in control of DNA methylation during preimplantation
development. The exact pattern of methylation in the bovine embryo has not been …

Successful embryonic development is dependent on factors secreted by the reproductive
tract. Dickkopf-1 (DKK1), an antagonist of the wingless-related mouse mammary tumor virus …

Background In broilers, high ambient temperature can result in reduced feed consumption,
digestive inefficiency, impaired metabolism, and even death. The broiler sector of the US …

Background The first distinct differentiation event in mammals occurs at the blastocyst stage
when totipotent blastomeres differentiate into either pluripotent inner cell mass (ICM) or …

Knowledge of the molecules used by the maternal reproductive tract to regulate
development of the preimplantation embryo is largely incomplete. The goal of the present …

Objectives were to evaluate the role of canonical WNT signaling in development of the
preimplantation embryo. Signaling was activated with 2-Amino-4-(3, 4-(methylenedioxy) …

The goal was to understand the role of heat shock at the zygote stage in causing infertility.
Culture at 40° C reduced the percentage of inseminated oocytes that became a morula or …
