Cloning research. Researcher using a needle and syringe to extract oocyte cells from a sheep ovary. Domestic sheep (Ovis aries) oocytes are used in cloning a rare type of wild sheep called a mouflon (Ovis orientalis musimon), which lives on the islands of Sardinia and Corsica. During cloning, nuclear material is removed from the sheep oocytes and is replaced with that from mouflon body (somatic) cells. The resulting cloned oocyte is cultured to the embryo stage and implanted into a foster sheep for pregnancy. The first cloned mouflon was born by this method in October 2000 at the University of Teramo in Italy. Cloning could aid mouflon conservation.
