China became the first country to clone a monkey using non-reproductive cells, reducing the
need to breed lab monkeys and paving the way for more accurate, effective and affordable animal tests for new drugs, scientists said on Thursday .
By December, the Institute of Neuroscience of the Chinese Academy of Sciences had created two clone macaques(猕猴) named”Zhong Zhong” and “Hua Hua” by nuclear transferring of somatic cells(体细胞)-any cell in the organism other than reproductive cells.
Tetra, a monkey born in 1999, is the world's first cloned monkey, but it was done by using a simpler method called embryo splitting(胚胎分割); but it could only generate four cloned offspring at a time and cannot be genetically changed to suit the experimental need.
Cloning a monkey using somatic cells has been a world-class challenge because it is a primate(灵长类) that shares its genetic makeup, and therefore all of its complexity, with humans.
For drug and other lab tests, scientists have to purchase monkeys from all over the world, which is costly and bad for the environment, and produces inaccurate results because each monkey might have different genes.
By cloning monkey using somatic cells, we can massively cultivate large numbers of genetically identical offspring in a short amount of time, and we can even change their genes to suit our needs. This can save time, cut down experiment costs, and produce more accurate results, leading to more effective medicine.
Sun Qiang, director of the non-human primate research facility at the institute, said most of the drug trials are currently done on lab mice. However, drugs that work on mice might not work or even have severe side effects on humans because the two species are so different
“Monkeys and humans are both primates, so they are much closely related and testing on monkeys is supposed to be as effective as testing on humans,”he said. This is especially useful in testing drugs for neural(神经的) diseases such as Parkinson’s disease, metabolic syndrome(代谢综合症) and immune system diseases, and tumors, he added.
“This achievement will help China lead the world research in the international science projects related to neural mapping of primate brains, \Japan, and European countries are also very capable, and they will quickly catch up with China after the monkey cloning technology is made public, \
“This means we have to innovate continuously and work extra hard this year to stay ahead,\said.
