  • However, there is only one report in which cloned animals have been produced from embryos reconstructed by transferring differentiated cells into preactivated recipient oocytes [ 8] and the ability of preactivated recipient oocytes to reprogram differentiated cells is now in debate.

  • When bovine somatic cells were transferred into preactivated recipient oocytes, the resulting reconstructed embryo development was limited, since all embryos arrested at the 8-cell stage regardless of the cell cycle of the donor cells [ 14].

  • Because embryonic genome activation of bovine embryos occurs between the 8- to 16-cell stages [ 21], preactivated recipients may not reprogram somatic nuclei.

  • In the preactivated oocyte, the nuclear membrane of the donor cells remains intact due to the low activity of MPF and DNA synthesis occurs according to the original cell cycle stage at the time of nuclear transfer [ 12] and nuclear reprogramming occurs during the expansion of the donor nucleus [ 18, 19].
