Research Abstract |
Firstly, it was indicated that CMRL-1066 medium, generally using for macaque monkey embryos, were available as the culture medium of monkey-rabbit interspecies somatic cell nuclear transfer embryos. In addition, by nuclear transfer using cynomolgus monkey somatic cells arrested at metaphase of cell cycle by nocodazole, the metaphase stage was maintained in transferred rabbit oocyte. It was clarified that activation by a combination of ionomycin and cycloheximide was suitable for nuclear transfer using the somatic cells at metaphase. Development to 8-cell stage of the interspecies nuclear transfer embryos was improved by using MG132. In the animals that collection of many oocytes are difficult, these results showed that the interspecies nuclear transfer was available for examination of the basic techniques.
