Dolly ( sheep ) - wikipedia Dolly ( sheep ) Dolly Dolly 's taxidermied remains Other name ( s ) 6LLS ( code name ) Species Domestic sheep, Finn - Dorset Sex Female 5 July 1996 Roslin Institute, Edinburgh, Scotland 14 February 2003 ( aged 6 ) Roslin Institute, Edinburgh, Scotland Resting place National Museum of Scotland ( remains on display ). Nation from United Kingdom ( Great Britain ) Known for First mammal cloned from an adult somatic cell Offspring Six lambs ( Bonnie ; twins Sally and Rosie ; triplets Lucy, Darcy and Cotton ) Named after Dolly Parton Cause of death Lung disease and severe arthritis Dolly ( 5 July 1996 -- 14 February 2003 ) was a female domestic sheep, and the first mammal cloned from an adult somatic cell, using the process of nuclear transfer. Contents 1 Genesis 2 Birth 3 Life 4 Death 5 Legacy 6 References 7 External links Genesis Dolly was cloned by Keith Campbell, Ian Wilmut and colleagues at the Roslin Institute, part of the University of Edinburgh, Scotland, and the biotechnology company PPL Therapeutics, based near Edinburgh. The funding for Dolly 's cloning was provided by PPL Therapeutics and the UK 's Ministry of Agriculture. She was born on 5 July 1996 and died from a progressive lung disease five months before her seventh birthday. She has been called `` the world 's most famous sheep '' by sources including BBC News and Scientific American. The cell used as the donor for the cloning of Dolly was taken from a mammary gland, and the production of a healthy clone therefore proved that a cell taken from a specific part of the body could recreate a whole individual. On Dolly 's name, Wilmut stated `` Dolly is derived from a mammary gland cell and we could n't think of a more impressive pair of glands than Dolly Parton 's ''. Birth Dolly was born on 5 July 1996 and had three mothers ( one provided the egg, another the DNA and a third carried the cloned embryo to term ). She was created using the technique of somatic cell nuclear transfer, where the cell nucleus from an adult cell is transferred into an unfertilized oocyte ( developing egg cell ) that has had its cell nucleus removed. The hybrid cell is then stimulated to divide by an electric shock, and when it develops into a blastocyst it is implanted in a surrogate mother. Dolly was the first clone produced from a cell taken from an adult mammal. The production of Dolly showed that genes in the nucleus of such a mature differentiated somatic cell are still capable of reverting to an embryonic totipotent state, creating a cell that can then go on to develop into any part of an animal. Dolly 's existence was announced to the public on 22 February 1997. It gained much attention in the media. A commercial with Scottish scientists playing with sheep was aired on TV, and a special report in TIME Magazine featured Dolly the sheep. Science featured Dolly as the breakthrough of the year. Even though Dolly was not the first animal cloned, she received media attention because she was the first cloned from an adult cell. Life The cloning process that produced Dolly Dolly lived her entire life at the Roslin Institute in Edinburgh. There she was bred with a Welsh Mountain ram and produced six lambs in total. Her first lamb, named Bonnie, was born in April 1998. The next year Dolly produced twin lambs Sally and Rosie, and she gave birth to triplets Lucy, Darcy and Cotton in the year after that. In late 2001, at the age of four, Dolly developed arthritis and began to walk stiffly. This was treated with anti-inflammatory drugs. Death On 14 February 2003, Dolly was euthanised because she had a progressive lung disease and severe arthritis. A Finn Dorset such as Dolly has a life expectancy of around 11 to 12 years, but Dolly lived 6.5 years. A post-mortem examination showed she had a form of lung cancer called ovine pulmonary adenocarcinoma, also known as Jaagsiekte, which is a fairly common disease of sheep and is caused by the retrovirus JSRV. Roslin scientists stated that they did not think there was a connection with Dolly being a clone, and that other sheep in the same flock had died of the same disease. Such lung diseases are a particular danger for sheep kept indoors, and Dolly had to sleep inside for security reasons. Some in the press speculated that a contributing factor to Dolly 's death was that she could have been born with a genetic age of six years, the same age as the sheep from which she was cloned. One basis for this idea was the finding that Dolly 's telomeres were short, which is typically a result of the aging process. The Roslin Institute stated that intensive health screening did not reveal any abnormalities in Dolly that could have come from advanced aging. In 2016 scientists reported no defects in thirteen cloned sheep, including four from the same cell line as Dolly. The first study to review the long - term health outcomes of cloning, the authors found no evidence of late - onset, non-communicable diseases other than some minor examples of osteoarthritis and concluded `` We could find no evidence, therefore, of a detrimental long - term effect of cloning by SCNT on the health of aged offspring among our cohort. '' Legacy After cloning was successfully demonstrated through the production of Dolly, many other large mammals were cloned, including pigs, deer, horses and bulls. The attempt to clone argali ( mountain sheep ) did not produce viable embryos. The attempt to clone a banteng bull was more successful, as were the attempts to clone mouflon ( a form of wild sheep ), both resulting in viable offspring. The reprogramming process that cells need to go through during cloning is not perfect and embryos produced by nuclear transfer often show abnormal development. Making cloned mammals was highly inefficient -- in 1996 Dolly was the only lamb that survived to adulthood from 277 attempts. By 2014 Chinese scientists were reported to have 70 -- 80 % success rates cloning pigs and in 2016, a Korean company, Sooam Biotech, was producing 500 cloned embryos a day. Wilmut, who led the team that created Dolly, announced in 2007 that the nuclear transfer technique may never be sufficiently efficient for use in humans. Cloning may have uses in preserving endangered species and may become a viable tool for reviving extinct species. In January 2009, scientists from the Centre of Food Technology and Research of Aragon, in northern Spain announced the cloning of the Pyrenean ibex, a form of wild mountain goat, which was officially declared extinct in 2000. Although the newborn ibex died shortly after birth due to physical defects in its lungs, it is the first time an extinct animal has been cloned, and may open doors for saving endangered and newly extinct species by resurrecting them from frozen tissue. In July 2016, four identical clones of Dolly ( Daisy, Debbie, Dianna, and Denise ) were alive and healthy at nine years old. Scientific American concluded in 2016 that the main legacy of Dolly the sheep has not been cloning of animals but in advances into stem cell research. After Dolly, researchers realised that ordinary cells could be reprogrammed to induced pluripotent stem cells which can be grown into any tissue.
