A cloned rhesus monkey has survived for more than two years and has led to “valuable insights” into the scientific process, according to experts.<\/p>\n

Scientists in China used a modified version of the same technique that was used to create Dolly the sheep, the world’s first cloned mammal.<\/p>\n

Out of the 113 cloned embryos, 11 were implanted into surrogate monkeys, but only one survived. It has been named ReTro.<\/p>\n

The team said that although the success rate of producing viable and healthy clones is low – less than 1% in this case – it pushes forward the understanding of primate cloning.<\/p>\n

The world’s first cloned monkeys – a pair of identical long-tailed macaques – were created six years ago by the same researchers, led by Qiang Sun and Zhen Liu of the Chinese Academy of Sciences in Shanghai.<\/p>\n

At that time, the researchers wanted to create populations of genetically uniform monkeys that could be customised for research into human diseases.<\/p>\n

It also raised major ethical questions by bringing the world closer to human cloning.<\/p>\n

But experts now say these fears “were entirely unfounded” and the efficiency of the cloning process still remains low.<\/p>\n

Writing in the journal Nature Communications, the authors said: “These discoveries provide valuable insights into the reprogramming mechanism of monkey SCNT [single-cell nuclear transfer] and introduce a promising strategy for primate cloning.”<\/p>\n

Also commenting on the findings, Dr Lluis Montoliu, a researcher at the National Centre for Biotechnology in Spain, who was not involved in the study, said: “Both the cloning of macaques and rhesus monkeys demonstrate two things.<\/p>\n

“First, it is possible to clone primates.<\/p>\n

“And second, no less important, it is extremely difficult to succeed with these experiments, with such low efficiencies, once again ruling out human cloning.”<\/p>\n

Dolly made history nearly three decades ago after being cloned at Edinburgh’s Roslin Institute.<\/p>\n

It was the first time scientists had managed to clone a mammal from an adult cell, taken from the udder of a Finn Dorset sheep.<\/p>\n

Since then many other mammals have been cloned using the same SCNT technique, which involves transferring cell nucleus DNA to a donated egg cell that is then prompted to develop into an embryo.<\/p>\n

They include sheep, cattle, pigs, dogs, cats, mice and rats and long-tailed monkeys.<\/p>\n<\/p><\/div>\n
