Abstract 

Epigenetic reprogramming intensely occurs in somatic-cell nuclear transfer (SCNT) embryos, which highlights the importance of proper expressions of reprogramming-related genes in SCNT embryos. We here assessed gene expression profiles (GEPs) difference between bovine blastocyst groups derived by in-vitro fertilization (IVF) or SCNT; in SCNT, cumulus cells and ear skin fibroblasts were used for cSCNT and fSCNT blastocysts, respectively. We obtained GEPs of 15 reprogramming-related genes in single blastocysts using multiplex PCR and found a broad range of variations in their GEPs. Weighted root-mean-square deviation (wRMSD) analysis, which calculates the deviation of SCNT blastocysts' GEPs from IVF blastocysts' mean GEP, found a significant difference between IVF and fSCNT and between cSCNT and fSCNT blastocysts (p < 0.001) but not between IVF and cSCNT. Since the fibroblasts' GEP was more distant from the IVF blastocysts' than the cumulus cells', it might partly explain the less similarity of fSCNT blastocysts' GEPs to the IVF's mean GEP. Our wRMSD method succeeds in expressing in figures how different two comparable embryo groups of different derivations are in GEP, which would be useful to select a better embryo derivation protocol among the candidates prior to field applications.
