    • Methods and compositions are provided for producing at least one donor cell that has a genome identical to that of a host. In the subject methods, an embryo is first produced by combining a nucleus obtained from a cell of said host with a recipient cell, e.g., an enucleated oocyte. The resultant embryo is then matured under conditions sufficient to produce a non-sentient organism that includes the donor cell. Finally, the donor cell is harvested from the non-sentient organism for subsequent use. Also provided are kits for use in practicing the subject invention. The subject methods find use in a variety of different applications, including tissue and organ transplant applications.
    • 提供了用于产生至少一个具有与宿主基因组相同的基因组的供体细胞的方法和组合物。 在本发明方法中,首先通过将从所述宿主的细胞获得的细胞核与受体细胞(例如去核卵母细胞)组合来产生胚胎。 然后在足以产生包括供体细胞的非感兴趣生物体的条件下,使得到的胚胎成熟。 最后,从非有意识的生物体收获供体细胞以供随后使用。 还提供了用于实践本发明的试剂盒。 主题方法可用于各种不同的应用,包括组织和器官移植应用。

    • A method of reconstituting an animal embryo involves transferring a diploid nucleus into an oocyte which is arrested in the metaphase of the second meiotic division. The oocyte is not activated at the time of transfer, so that the donor nucleus is kept exposed to the recipient cytoplasm for a period of time. The diploid nucleus can be donated by a cell in either the G0 or G1 phase of the cell cycle at the time of transfer. Subsequently, the reconstituted embryo is activated. Correct ploidy is maintained during activation, for example, by incubating the reconstituted embryo in the presence of a microtubule inhibitor such as nocodazole. The reconstituted embryo may then give rise to one or more live animal births. The invention is useful in the production of transgenic animals as well as non-transgenics of high genetic merit.
    • 重建动物胚胎的方法涉及将二倍体核转移到在第二次减数分裂期的中期被逮捕的卵母细胞。 卵母细胞在转移时不被激活,使得供者核细胞保持暴露于受体细胞质一段时间。 二倍体核可以在转移时由细胞G0或G1期的细胞捐献。 随后,重建的胚胎被激活。 在活化期间维持正确的倍性,例如通过在微管抑制剂例如诺考达唑的存在下孵育重构的胚胎。 然后,重建的胚胎可能会产生一种或多种活的动物分娩。 本发明可用于生产转基因动物以及具有高遗传优点的非转基因植物。
