objective: nuclear transfer-embryonic stem cells (nt-escs) are genetically identical to the donor’s cells; provide a renewable source of tissue for replacement, and therefore, decrease the risk of immune rejection. trichostatin a (tsa) as a histone deacetylase inhibitor (hdaci) plays an important role in the reorganization of the genome and epigenetic changes. in this study, we examined whether...
Nuclear transfer to eggs or oocytes provides a potential route for cell-replacement therapies because oocytes directly reprogram transplanted mammalian somatic-cell nuclei such that they have an embryo-like pattern of gene expression. This includes a large increase in the mRNA level of the stem-cell marker gene oct4. We have developed a novel procedure to identify new proteins that greatly incr...
To investigate the embryonic genome organization upon fertilization and somatic cell nuclear transfer (SCNT), we tracked HP1β and CENP, two well-characterized protein markers of pericentric and centromeric compartments respectively, in four types of embryos produced by rabbit in vivo fertilization, rabbit parthenogenesis, rabbit-to-rabbit, and bovine-to-rabbit SCNT. In the interphase nuclei of ...
Cell differentiation is remarkably stable but can be reversed by somatic cell nuclear transfer, cell fusion, and iPS. Nuclear transfer to amphibian oocytes provides a special opportunity to test transcriptional reprogramming without cell division. We show here that, after nuclear transfer to amphibian oocytes, mitotic chromatin is reprogrammed up to 100 times faster than interphase nuclei. We f...
