Methods for producing transgenic animals
First Claim
1. A method for producing a transgenic animal comprising the steps of:
- transferring transgenic embryos, which were produced by transferring exogenous DNA from spermatozoa, to oocytes by intracytoplasmic sperm injection and cultured to an embryonic stage, to the oviducts of surrogate females; and
producing a transgenic animal by parturition.

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.

65. A method for producing a transgenic primate comprising the steps of:
-
transferring said transgenic embryos which were produced by dissociating blastomeres from an embryo, removing the nuclei from the blastomeres, injecting the blastomere nuclei into enucleated oocytes by intracytoplasmic nuclear injection, and activating and culturing oocytes to an embryonic stage, to the oviducts of surrogate females; and
producing a transgenic primate by parturition. - View Dependent Claims (66, 67, 68, 69)
