Sir Ian Wilmut, cloning pioneer, dies at 79. He created Dolly the Sheep in 1996, sparking global discussion on cloning ethics. His work at the Roslin Institute for animal biosciences was critical to research on regenerative medicine, gene editing, and cloning of animals, humans, and extinct species. He was knighted in 2008 and retired in 2012. His legacy continues to fuel advances in the field of regenerative medicine.
Ian Wilmut, the cloning pioneer whose work was critical to the creation of Dolly the Sheep in 1996, has died, the University of Edinburgh in Scotland said on September 11. He was 79.
Wilmut set off a global discussion about the ethics of cloning when he announced that his team at the university's Roslin Institute for animal biosciences had cloned a lamb using the nucleus of a cell from an adult sheep.
Initially referred to as “6LL3” in the academic paper describing the work, the lamb was later named Dolly, after the singer Dolly Parton.
The lamb's cloning was the first time scientists were able to coax a mature adult cell into behaving like a cell from a newly fertilized embryo in order to create a genetically identical animal.
While Dolly's creation was heralded as a revolution by some scientists, it unnerved many, with critics calling such experiments unethical.
The year after Dolly's creation, US President Bill Clinton imposed a ban on the use of federal funds for human cloning but stopped short of banning all cloning research.
Dolly's creation prompted other scientists to clone animals including dogs, cats, horses and bulls. Dolly also spurred questions about the potential cloning of humans and extinct species.
