Differential transcriptome dynamics during the onset of conceptus elongation and between female and male porcine embryos

this study was designed to analyze global gene expression in porcine embryos during the preimplantation period (Day 8, 10, and 12 of pregnancy) with the aims of (i) characterizing the dynamics of gene expression profiles and the involved functions and thereby (ii) identifying the chromosome X inactivation profile between female and male Overall design: Female and male embryos were isolated from three stages (Day 8, 10, and 12) (each group n=5), respectively, and then subjected to RNA-sequencing (RNA-Seq).
