Dolly (sheep)
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 Ministry of Agriculture. She was born on 5 July 1996 and died from a progressive lung disease five months before her seventh birthday (the disease was not considered related to her being a clone). She has been called "the world's most famous sheep" by sources including BBC News and "Scientific American".
Snuppy
After Dolly the sheep was cloned in 1996, scientists had managed to clone numerous other animals, including cats, cows, gaur, horses, mice, mules, pigs, rabbits and rats but had been unable to successfully clone a dog due to the problematic task of maturing a canine ovum in an artificial environment. After several failed attempts by other scientists, Woo Suk Hwang, a lead researcher at Seoul National University, was able to successfully create a clone using tissue from the ear of a 3-year-old Afghan hound. 123 surrogate mothers were used to carry the embryos, of which 1,095 were implanted, the procedure resulted in only three pregnancies; one resulted in a miscarriage, the other pup was born successfully but died of pneumonia three weeks after birth, the successful clone was carried by a Labrador Retriever. From the original 1,095 embryos to the final two puppies, this placed the success rate of the project at less than two tenths of a percent. Snuppy was named as a portmanteau of the initials of the Seoul National University (SNU) and the word "puppy".
