Dolly was a domestic sheep who became the first mammal to be cloned from an adult somatic cell via the nuclear transfer method.
Keith Campbell, Ian Wilmut, and colleagues at the Roslin Institute, part of the University of Edinburgh in Scotland, and PPL Therapeutics, a biotechnology business situated near Edinburgh, cloned Dolly. PPL Therapeutics and the Ministry of Agriculture contributed financing for Dolly's cloning. She was born on July 5, 1996, and died on February 14, 2003, five months before her seventh birthday, from a progressive lung condition (the ailment was not thought to be related to her being a clone). BBC News and Scientific American have both referred to her as "the world's most famous sheep."
The cell that was used to clone
Dolly was taken from a mammary gland, and the creation of a healthy
clone established that a cell taken from a specific section of the body
could duplicate an entire person. "Dolly is derived from a mammary gland
cell, and we couldn't think of a more magnificent set of glands than
Dolly Parton's," Wilmut said of Dolly's moniker.
