Faithful expression of imprinted genes in donor cells of SCNT cloned pigs

FEBS Lett. 2015 Jul 22;589(16):2066-72. doi: 10.1016/j.febslet.2015.06.016. Epub 2015 Jun 25.

Abstract

To understand if the genomic imprinting status of the donor cells is altered during the process of SCNT (somatic cell nuclear transfer), cloned pigs were produced by SCNT using PEF (porcine embryonic fibroblast) and P-PEF (parthenogenetic-PEF) cells as donors. Then, the gene expression and methylation patterns of H19, IGF2, NNAT and MEST were compared between PEF vs. C-PEF (cloned-PEF), P-PEF vs. CP-PEF (cloned-P-PEF), respectively. Taken together, the results revealed that there was no significant difference in the expression of imprinted genes and conserved genomic imprints between the donor and cloned cells.

Keywords: Cloned pig; Imprinted gene; Parthenogenetic; Porcine embryonic fibroblast; Somatic-cell nuclear transfer.
