[Cloned goats produced from the somatic cells of an adult transgenic goat].

This study was carried out to examine the effect of different donor cell type and micro-manipulation on the development of reconstituted embryos. Cultured mural cumulus cells or fibroblast cells from an adult transgenic goat expressing human erythropoietin(rhEPO) were used as the donor cells in nuclear transfer experiments. The reconstituted eggs were generated by transferring fibroblast cells or cumulus cells into the perivitelline space of enucleated M II oocytes and then followed by electrofusion and activation.
