X-linked gene transcription patterns in female and male in vivo, in vitro and cloned porcine individual blastocysts.
To determine the presence ckf snafu 2.0 of sexual dimorphic transcription and how in vitro culture environments influence X-linked gene transcription patterns in preimplantation embryos, we analyzed mRNA expression levels in in vivo-derived, in vitro-fertilized (IVF), and cloned porcine blastocysts.Our results clearly show that sex-biased expressio
