Reproductive cloning also could be used to repopulate endangered animals or animals that are difficult to breed.In 2024the first clone of an endangered wild animal was borna wild ox called a gaur.The young gaur died from an infection about 48 hours after its birth.In 2024scientists in Italy reported the successful cloning of a healthy baby mouflonan endangered wild sheep.The cloned mouflon is living at a wildlife center in Sardinia.Other endangered species that are potential candidates for cloning include the African bongo antelopethe Sumatran tigerand the giant panda.Cloning extinct animals presents a much greater challenge to scientists because the egg and the surrogate needed to create the cloned embryo would be of a species different from the clone.

Therapeutic cloning technology may some day be used in humans to produce whole organs from single cells or to produce healthy cells that can replace damaged cells in degenerative diseases such as Alzheimer's or Parkinson's.Much work still needs to be done before therapeutic cloning can become a realistic option for the treatment of disorders.
