    • A method is described for the production of an animal (offspring) by the process of nuclear transfer. The animal may be produced using donor genetic material in cells taken directly from any stage of an animal, such as an embryo, foetus or adult or from cell cultures established from material from any stage of an animal, such as embryonic, foetal or adult material. The process may be used to introduce genetic modifications into the resultant offspring by genetic manipulation and selection of the cells to act as nuclear donors prior to embryo reconstruction.The present invention provides a method of reconstituting an animal embryo, the process comprising transferring a nucleus into a first oocyte followed by removing and transferring the nucleus from the oocyte to a further oocyte or to an enucleated fertilized zygote.
    • 描述了通过核转移过程生产动物(后代)的方法。 可以使用来自动物(例如胚胎,胎儿或成年人)的任何阶段的细胞中的供体遗传物质产生动物,或者可以从动物任何阶段的材料建立的细胞培养物,例如胚胎,胎儿或成人材料 。 该过程可以用于通过遗传操作和细胞的选择将遗传修饰引入所产生的后代中,以在胚胎重建之前充当核供体。 本发明提供了一种重建动物胚胎的方法,该方法包括将细胞核转移到第一卵母细胞中,然后将细胞核从卵母细胞去除并转移到另外的卵母细胞或去核受精受精受精卵。
