    Department of Basic Animal and Veterinary Sciences, Royal Veterinary and Agricultural University, Frederiksberg C, Denmark
    Mol Reprod Dev 74:1428-35. 2007
    ..However, localization of these two proteins to the nucleolar compartments was negatively affected by the alpha-amanitin treatment. Consequently, functional nucleoli were not established...
  2. doi request reprint Nuclear and nucleolar reprogramming during the first cell cycle in bovine nuclear transfer embryos
    Olga Østrup
    Constantin the Philosopher University, Nitra, Slovak Republic
    Cloning Stem Cells 11:367-75. 2009
    ..At 1-3 hpa, chromatin gradually decondensed toward the nucleus periphery and nuclear envelope reformed. From 4 hpa, the somatic cell nucleus gained a PN-like appearance and displayed NPBs suggesting ooplasmic control of development...

    Olga Østrup
    Institute for Basic Medical Sciences, Faculty of Medicine, University of Oslo and Norwegian Center for Stem Cell Research, Oslo, Norway
    PLoS ONE 8:e61547. 2013
    ..Moreover, comparison with mouse and human embryos showed striking overlap in functional annotation of transcripts during the EGA, suggesting conserved basic mechanisms regulating establishment of totipotency in mammalian development...

    IBHV, University of Copenhagen, Frederiksberg C, Denmark
    Mol Reprod Dev 76:132-41. 2009
    ..NT-MEF embryos displayed normal targeting but delayed activation of nucleolar proteins. Contrary, in NT-HM1 embryos, both of these processes were delayed...
