Abstract: The present invention is directed to various methodologies to make NT a practical procedure for animals, specifically, primates including human and non-human primates. Furthermore, the methods and molecular components provided by the present invention provide a practical means for producing embryos with desired characteristics. In a specific embodiment, the methodology of the present invention comprises introducing nuclei having desired characteristics along with one or more molecular components into an enucleated egg, thus creating a nuclear transfer construct, culturing the egg to produce a viable embryo, transferring the embryo to the oviducts of a female, and producing a cloned animal.

Abstract: The present invention relates to methods for producing transgenic animals. Specifically, the methods of the present invention include production of a transgenic animal by transgenic intracytoplasmic sperm injection, retroviral gene transfer, intracytoplasmic nuclear injection, and pronuclear injection. In addition, the present invention also relates to methods for using transgenic animals as models for human disease and diagnosis. In particular, these transgenic animals may be used as models for embryo and fetal development, as models to assess the safety and efficacy of drug therapy and gene therapy, and as models for disease diagnosis. The methods of the present invention are also directed to methods of using transgenic embryonic cells to treat human diseases.

Abstract: The present invention relates to the clonal propagation of primate offspring by embryo splitting. Here, genetically identical nonhuman embryos may be produced as twin and larger sets by separation and reaggregation of blastomeres of cleavage-stage embryos. Furthermore, the present invention also relates to methods for producing embryonic stem cells and transgenic embryonic stem cells isolated from dissociated blastomeres.
