    • The present invention concerns the use of chromosomal replacement techniques in the context of producing cloned and transgenic animals, in order to correct chromosome abnormalities or alter autosomal genotypes, and provide for novel breeding pairs by replacing the sex chromosome in animals to be cloned. Replacement of a sex chromosome, or an X or Y chromosome, will result in animals that are autosomally isogenic and sexually non-isogenic (AISN), with ''autosomally isogenic'' meaning that the paired sets of autosomes (non-sex chromosomes) in each animal are isogenic or identical. Also included in the invention are animals that are both ''autosomally'' and ''allelically'' isogenic whereby each particular pair of chromosomes is internally isogenic or identical within a single animal as well as between animals. Such animals are particularly useful in generating a line of cloned mammals using sexual reproduction, without having to undergo nuclear transfer in order to propagate cloned animals.
    • 本发明涉及在产生克隆和转基因动物的情况下使用染色体替代技术,以校正染色体异常或改变常染色体基因型,并通过替代待克隆的动物中的性染色体来提供新的育种配对。 替代性染色体或X或Y染色体将导致常染色体同源和性非同基因(AISN)动物,其中“常染色体同基因”意味着成对的常染色体组(非性染色体) 在每只动物中是同基因的或相同的。 本发明还包括“常染色体”和“等位基因”同源的动物,其中每对特定的染色体在单个动物内以及动物之间在内部是同基因的或相同的。 这种动物在利用有性生殖产生一系列克隆哺乳动物时特别有用,而不必为了繁殖克隆动物而进行核转移。

    • Animal cells which are totipotent for nuclear transfer (TNT cells) can be isolated from the embryonic disc of the blastodermic vesicle of an ungulate, or the equivalent tissue of an embryo at an equivalent stage in non-ungulate species. TNT cells can be cultured in vitro, which allows cloning as desired and genetic manipulation, for example to introduce a transgene. Their nuclei can be transferred to suitable recipient cells and embryos reconstituted. In this way, animals of high genetic merit may be cloned and transgenic animals may be generated by mass transformation techniques across a broader range of species than is accessible with embryonic stem cell technology and without reliance on pronuclear microinjection.
    • 可用于核转移(TNT细胞)的全能动物细胞可以从有蹄类动物的胚胎性小泡的胚胎盘或非同型物种等效阶段的胚胎的等效组织中分离出来。 可以在体外培养TNT细胞,其允许根据需要进行克隆和遗传操作,例如引入转基因。 它们的核可以转移到合适的受体细胞中并重建胚胎。 以这种方式,可以克隆高遗传优点的动物,并且可以通过跨越更广范围物种的大规模转化技术产生转基因动物,而不是通过胚胎干细胞技术可获得的,而不依赖于原核显微注射。
