Scheme of pig cloning from embryonic or adult donor cells. An unfertilized, enucleated oocyte from an adult female pig is fused with the nucleus from an embryonic or adult donor cell via electric pulse to form a new cell. This new cell undergoes division in a test tube (culture medium) into an early stage embryo, which is implanted into the uterus of a sow. Ultimately, the sow gives birth to piglets that have the same genetic makeup as the animal that donated the embryonic or somatic cell
