Scientist Profile: |
In July
1997, building upon their success of the creation of Dolly, the first animal cloned from adult cells, Ian Wilmut and Keith Campbell
created Polly, a Poll Dorset lamb cloned from
skin cells grown in a lab and genetically altered to
contain a human gene. Polly's birth signified the
first step in the application of cloning technology to
the production of a useful product. Most scientists
believe that most beneficial application of cloning will
come from the exact reproduction of animals genetically
altered to produce human proteins or organs more easily accepted
in transplants. Wilmut and Campbell's creation of Polly
surprised the scientific community by how fast cloning
technology was progressing. The cloning of genetically
altered farm animals was not expected for another five
years.
