Abstract

The creation of transgenic animals has application in the following areas of pharmaceutical and biomedical research: the production of biopharmaceuticals for human use; the production of organs for xenotransplantation; and the generation of animal models for human genetic diseases. Nuclear transfer technology offers a more precise and efficient way of performing genetic modification and creating transgenic animals than the more traditional method of pronuclear microinjection. This paper will review nuclear transfer as ameans of producing transgenic animals; introduce advantages nuclear transfer technology offers in the field of animal transgenesis; and highlight some of the animal welfare issues and ethical concerns raised by the generation and use of transgenic animals in the aforementioned fields of study. Finally, the influence of objectifying language and terminology used to describe transgenic animals will be considered, and the impact of phrases such as “living bioreactor” and “spare part supplier” examined.
