Enucleated

Five enucleated fragments were cut from the egg immediately after they were released and kept for an hour in the sterilized water;

For the nuclear transfer of somatic cells in farm animals, donor cells are fused with enucleated oocytes by eletric stimulation.

When nuclei of medaka adult somatic cells were used as donors for transfer into enucleated recipient eggs, successful development of transplant embryos was markedly reduced (unpublished data); however, fertile, diploid NTs had been produced in previous studies in which embryonic cell nuclei were transferred into enucleated eggs.
