TranscriptomicsPlacental gene expression in pregnancies established after the transfer of day 7 blastocysts derived from in vitro (IVP), somatic cell nuclear transfer (SCNT) and in vivo (AI) embryos
Aberrant placental gene expression associated with culture condition and/or deficiencies in transcriptome reprogramming are hypothesized to be the major cause of SCNT and IVP inefficiencies. Therefore, the main objective of this study was to invesitgate the dysregulated genes, molecular pathways and...

TranscriptomicsBovine Embryonic Developmental Competence Is Predicted By Expression Levels Of Genes Related To Oxidative Stress Response
The aberrant gene expression of early bovine embryos are a major cause for developemtal arrest. Therefore our aim was to detect transcriptomic fingerprints which correlate with the subsequent developmental competence of a two cell stage embryo. 2-cell stage embryos were bisected; one blastomere was ...

TranscriptomicsGene expression analysis of bovine day 16 embryos obtained from SCNT and IVP pregnancies
In vitro production systems, as well as cloning technology, may lead to persistent aberrations of gene expression patterns during embryonic and fetal development. In order to get a global overview of gene expression alteration induced by in vitro environment and somatic cell nuclear transfer, we per...
