## Abstract The present study aimed to determine the influence of exogenous epidermal growth factor (EGF) on in vitro preimplantation porcine embryo development and its mRNA expression for EGF receptor (EGFR). Oocytes were aspirated from abattoir ovaries, selected and cultured in defined, proteinβf

Preimplantation development in mammals involves both the development of the embryo and the preparation of the uterus in anticipation of blastocysts implantation. Preparation of the uterus for implantation is primarily under the control of the ovarian sex steroids, estrogen and progesterone. Increasi
## Abstract The optimal oxygen tension for development of preimplantation mouse embryos to the blastocyst stage in vitro was found to be between 2.5% and 5%. Oneβ and twoβcell embryos had a more sharply defined range of oxygen tension capable of supporting development than 8βcell and morula stages.
