Nevertheless, nearly all SCNT embryos IL2RG neglect to develop to term due to undefined reprogramming defects. Here we identify histone H3 lysine 9 trimethylation (H3K9me3) of donor cell genome as a major epigenetic barrier for efficient reprogramming by SCNT. Comparative transcriptome analysis recognized reprogramming resistant regions (RRRs) that are expressed normally at 2-cell mouse embryos generated by IVF but not SCNT. RRRs are enriched for H3K9me3 in donor somatic cells, and its removal by ectopic expression of the H3K9me3 demethylase Urocanic acid Kdm4d not only reactivates the majority of RRRs, but also greatly improves SCNT efficiency. Furthermore, use of donor somatic nuclei depleted of H3K9 methyltransferases markedly enhances SCNT efficiency. Our study thus identifies H3K9me3 as a critical epigenetic barrier in SCNT-mediated reprogramming and provides a promising approach for improving mammalian cloning efficiency. disease modeling and cell/tissue-replacement therapies. Despite its huge potential, several technical limitations have prevented the practical use of SCNT. One such limitation is the extremely low efficiency in generating cloned Urocanic acid animals. For example, approximately half of mouse SCNT embryos display developmental arrest prior to implantation, and only 1C2% of embryos transferred to surrogate mothers can develop to term (Ogura et al., 2013). With the exception of bovine species, which have relatively higher rates of reproductive cloning efficiency (5 to 20%), the overall reproductive cloning efficiency in all other species is relatively low Urocanic acid (1 to 5%) (Rodriguez-Osorio et al., 2012). Similarly, the success rate for human ntESC establishment is also low owing to poor preimplantation development (10 to 25% to the blastocyst stage; Tachibana et al., 2013; Yamada et al., 2014). Given that developmental defects of SCNT embryos first appear at the time of zygotic genome activation (ZGA), which occurs.
