Keith Campbell (biologist)

From Wikipedia, the free encyclopedia

Biologist Professor Keith H. S. Campbell (born 1954) is an English biologist best known for being credited with the main role in the team that in 1996 first cloned a mammal, a Finn Dorset lamb named Dolly, from fully differentiated adult mammary cells. The work was published in February 1997.

Campbell grew up in Birmingham in England. He obtained his bachelor's degree in microbiology from the University of London and his doctoral degree from the University of Sussex(Bighton, UK).

Campbell's interest in cloning mammals was inspired by work done by Karl Illmensee and John Gurdon.

Working at the Roslin Institute since 1991, Campbell became involved with the cloning efforts lead by Ian Wilmut. In July 1995 Keith Campell, Bill Ritchie and Jim Mcwhir succeeded in producing a pair of lambs, Megan and Morag from embryonic cells, which had differentiated in culture. Then, in 1996, a team led by Ian Wilmut with Keith Campbell as the main (66% of the credit) contributor utilised the same technique and shocked the world by successfully cloning a sheep from adult mammary cells. Dolly, a Finn Dorset sheep, named after the singer Dolly Parton, was born in 1996 and lived to be 6 years old (dying from a viral infection and not old age, as has been suggested). Campbell has been attributed a key role because he had the crucial idea of co-ordinating the stages of the "cell cycle" of the donor somatic cells and the recipient eggs and using diploid quiscent or 'G0' arrested somatic cells as nuclear donors.

In 1998 Ritchie and Campbell in collaboration with PPL (Pharmaceutical Proteins Limited) created another sheep named 'Polly' . She was made from genetically altered skin cells containing a human gene.

In 2000, after joining PPL Ltd, Campbell and his PPL team (based in North America)were successful in producing the world's first piglets by somatic cell nuclear transfer (SCNT), the so called cloning technique. Furthermore, the PPL team based in Roslin, Scotland used the technique to produce the first gene targeted domestic animals as well as a range of animals producing human therapeutic proteins in their milk.

Campbell is currently (2006) Professor of Animal Development, School of Biosciences at the University of Nottingham where he contues to study embryo growth and differentiation. He supports the use of SCNT for the production of personalised stem cell therapies and for the study of human diseases and the use of cybrid embryo production to overcome the lack of human eggs available for research. Although stem cells can be isolated from embryonic, foetal and adult deriverd material and more recently by overexpression of certain genes for the production of so called induced pluripotent cells (iPS), he feels that at the present time all potential forms of stem cells should be used for research and developent of cell therapies.
