摘要: A nuclear transfer embryo is formed by destabilizing microtubules of an oocyte, whereby essentially all endogenous chromatin collects at a second polar body during meiosis of an oocyte. The oocyte is fused with the nucleus of a donor somatic cell of the same species of said oocyte prior to cessation of extrusion of the second polar body from the oocyte, thereby forming the nuclear transfer embryo. In one embodiment, the nuclear transfer embryo is employed to impregnate an animal, such as a mammal. In another embodiment, the donor nucleus is transgenic.

摘要: The invention pertains to the discovery that the presence of oocyte spindle associated factors in an enucleated oocyte improves oocyte quality and subsequently nuclear transfer. In particular, it was discovered that maintaining oocyte spindle factors in the oocyte after enucleation improves oocyte quality for use in nuclear transfer methodology.

摘要: The present invention pertains to methods for cloning animals. In particular, the invention includes methods of cloning an animal by combining a genome from an activated donor cell with an activated enucleated oocyte to thereby obtain a nuclear transfer embryo, and impregnating an animal with the nuclear transfer embryo in conditions suitable for gestation of a cloned animal. The invention further relates to methods of chemically enucleating an oocyte having a meiotic spindle apparatus by exposing the oocyte with a compound that destabilizes the meiotic spindle apparatus.
