Koreans produce world’s first cloned dog
South Korea’s pioneering stem cell scientist has cloned a dog, smashing another biological barrier and reigniting a fierce ethical debate — while producing a perky, lovable puppy.
The researchers, led by Woo-Suk Hwang, insist they cloned an Afghan hound, a resplendent supermodel in a world of mutts, only to help investigate human disease, including the possibility of producing stem cells for treatment purposes [...]

Scientists took the genetic material from the ear cell and placed it into an empty egg cell. This egg was then stimulated to start dividing and develop into an embryo.
