The first author Liu Zhen, a postdoctoral fellow, spent three years practicing and optimizing the SCNT procedure. He tested various methods to quickly and precisely remove the nuclear materials from the egg cell and promote the fusion of the nucleus-donor cell and enucleated egg.

"The SCNT procedure is rather delicate, so the faster you do it, the less damage to the egg you have, and Dr. Liu has a green thumb for doing this," said Sun.

This success means China will pioneer in disease and brain science research by taking cloned macaques as animal models, said Muming Poo, a co-author on the study who directs the Institute of Neuroscience of CAS Center for Excellence in Brain Science and Intelligence Technology.

"This is a key development in studying primate biology and making models of non-human primates," said Bai Chunli, president of the CAS.

The models designed for brain diseases will shed light on their study, intervention and even treatments.
