Project description:Pre-implantation embryos derived by in vitro fertilization differ in their developmental potential from embryos obtained in vivo. In order to characterize changes in gene expression profiles caused by in vitro culture environment, we employed microarray constructed from bovine embryo-specific cDNAs (BlueChip v., Université Laval, Québec) to compare in vitro cultured and in vivo derived bovine embryos at 4-cell and 8-cell stage.
Project description:Affymetrix Human GeneChips are used to profile gene expression of bovine tissues and embryos to identify uniquely expressed genes in bovine in-vitro fertilized embryos by comparing with seven bovine adult tissues through gene clustering
