Beijing( CNN) With his black, brown and white-hot wool, Longlong looks like most beagles. But the puppy has been sick with a blood-clotting disease since delivery — exactly what scientists in China had wanted.
The pup was cloned from Apple, a different puppy whose genome was edited to develop the disease atherosclerosis.
With that genetic message now coded in, the disease — a leading cause of strokeand heart sickness — was extended along to Longlong, who scientists will use to study the condition and its possible antidotes.
Longlong’s creator, Beijing-based biotech company Sinogene, said Longlong is the world’s first puppy cloned from a gene-edited donor. With Longlong’s birth, the scientists claimed that China had parallelled South Korea as a leader in canine cloning engineering.
South Korean scientists cloned the first pup, an Afghan hound reputation Snuppy, in 2005.
