The development of transgenic technology in the late 1970s and early 1980s transformed the laboratory mouse into a sophisticated "biological tool". Early breakthroughs, such as viral-mediated gene transfer and , allowed for the creation of founder lines that could transmit new traits to offspring. This capability enabled the study of specific gene functions—such as the role of oncogenes in cancer development—directly within a living host rather than in isolated cell cultures. Creating and Procuring Precision Models
Modern researchers primarily obtain these specialized models through two pathways: custom generation or commercial acquisition. Science Milestone: The first transgenic mice buy transgenic mice
The procurement and application of transgenic mice represent a cornerstone of modern biomedical research, bridging the gap between molecular genetics and whole-organism physiology. These animals, defined by the stable integration of foreign DNA into their genome, provide researchers with unparalleled insights into human disease mechanisms and therapeutic efficacy. The Evolution of Genetic Engineering The development of transgenic technology in the late
