The cells were cultured, and only their nuclei were removed. They were then injected into the unfertilized eggs of the Landrace breed, and the eggs were stimulated electrically for embryogenesis. The piglet weighed 1.2 kilograms at birth and its delivery was normal. Thirty-six embryos were implanted in the surrogate mother pigs, but only one was born. The piglet had black hair like that of the Meichan breed.
Genetic analysis confirms that it is a somatic-cell clone.
