The birth of Dolly challenged the scientific consensus that a nucleus from a terminally differentiated cell could not control the development of offspring. This led to the use of somatic cell nuclear transfer for animal cloning and genetically modified farm animals, facilitating research on gene function and the establishment of animal models for various human conditions and diseases.
For more than a century, the scientific consensus stated that a nucleus from a terminally differentiated cell would not be able to control the development of offspring. This theory was refuted by the birth of Dolly, the first animal generated by nuclear transfer using an adult somatic cell as a nuclear donor. Following this paradigm shift, a wide variety of animals has been cloned using somatic cell nuclear transfer. Coupled with modern genome engineering technology, somatic cell nuclear transfer has become the method of choice for the generation of genetically modified farm animals. This has opened new opportunities to study the function of genes and has led to the establishment of animal models for a variety of human conditions and diseases or to improve the health of livestock animals.
