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
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:Mouse oocytes and embryos from the germinal vesicle (GV) stage to the blastocyst stage were collected and treated with acidic Tyrode’s solution to remove the zona pellucida. We used 42.5 oocytes or embryos per sample at each developmental stage and identified the proteome during mouse pre-implantation development by label-free quantification.
