The Chinese Academy of Sciences (CAS) announced that the first body cell-cloned monkey Zhongzhong was born on November 27, 2017, and the second cloned monkey Huahua was born after 10 days. Cell, a top international academic journal, published the research in its cover story.

Since the birth of Dolly, the world's first cloned sheep, scientists from many countries have successfully cloned cows, rats, cats, dogs and other animals. But they have never been able to clone any non-human primate, the species closest to humans.

The DNA of Zhongzhong and Huahua were from the nuclei of a fetal female macaque monkey. Researchers extracted the fetal monkey's somatic cells (non-germinal cell) and planted them into several egg cells with their nuclei removed.

"It shows that China is taking the lead in establishing effective animal models to simulate human diseases," said Sun Qiang, a researcher at the Chinese Academy of Sciences.

Pu Muming, director of the Institute of Neuroscience of CAS, said that the successful cloning of monkeys will shed light on mechanism studies, intervention and treatment of diseases related to the brain, immune system, tumors, and metabolism. "This is a significant breakthrough in the field of life sciences," Pu added.

"Serving human health is the sole purpose of cloning non-human primates," Pu said.

Scientists believe that cloning monkeys will vastly promote studies to discover new treatments for human diseases.

CAS president Bai Chunli said that the achievement is not only significant to fundamental research, but also gives impetus to China to develop a brand new medical R&D chain based on the animal model of non-human primates, and will contribute to finding ways to cope with major challenges in the field of human health.
