Near completion of January, newborn monkeys Zhong Zhong and Hua Hua made their launching as the very first primate clones used a strategy called somatic cell nuclear transfer– the very same procedure which developed Dolly the sheep more than 20 years earlier.
The similar long-tailed macaques were born in November and December at the Chinese Academy of Sciences’ Institute of Neuroscience inShanghai Scientist Qiang Sun, director of the Nonhuman Primate Research Facility, states “there was much failure before we found a way to successfully clone a monkey” by eliminating the nucleus from an egg cell and changing it with that of donor cells from an aborted fetus.
The births of Zhong Zhong and Hua Hua have actually commonly been considered as a big clinical improvement, opening the possibility for experiments on great deals of genetically similar monkeys. They ‘d supply more precise models for research study surrounding human diseases.
Sun states “This will generate real models not just for genetically based brain diseases, but also cancer, immune, or metabolic disorders and allow us to test the efficacy of the drugs for these conditions before clinical use.”
Understandably, this has actually raised ethical issues, especially about human cloning. What isn’t really discussed as much are the animals who suffered throughout the procedure of producing Zhong Zhong and Hua Hua– and just how much the child monkeys will suffer themselves.
