The Rural Development Administration has succeeded in producing four piglets by injecting the semen from a cloned pig into a normal female pig.

The success has increased the possibility of producing pigs that are more suitable for xenotransplantation, or transplants between animals and humans.

The piglets are partially deprived of the Gal gene that is thought to be responsible for the rejections that result during interspecies transplants.

Piglets completely free of the gene will be born if one of the four piglets is able to reproduce with the semen-donor pig.

Organs from the piglets with no Gal genes are expected to be able to be transplanted into humans without immune rejection.
