Zhong Zhong and Hua Hua (female crab-eating macaques, 2017) – first successful cloning of primates using somatic cell nuclear transfer, the same method as Dolly, with the birth of two live female clones. Conducted in China in 2017. [65] [66] [67] [68]
The employment of adult somatic cells in lieu of embryonic stem cells for cloning emerged from the foundational work of John Gurdon, who cloned African clawed frogs in 1958 with this approach. The successful cloning of Dolly led to widespread advancements within stem cell research, including the discovery of induced pluripotent stem cells. [4]
[110] [111] The best current cloning techniques have an average success rate of 9.4 percent [112] (and as high as 25 percent [37]) when working with familiar species such as mice, [note 1] while cloning wild animals is usually less than 1 percent successful.
Cloning animals requires procedures that can cause pain and distress, and there can be high failure and mortality rates.” Being able to produce genetically identical monkeys could be useful ...
Commercial animal cloning is the cloning of animals for commercial purposes, including animal husbandry, medical research, competition camels and horses, pet cloning, and restoring populations of endangered and extinct animals. [1] The practice was first demonstrated in 1996 with Dolly the sheep.
The world’s first cloned black-footed ferret has given birth in a historic first for conservationists. Antonia the ferret successfully delivered two healthy kits after mating with Urchin, a ...
This technique is currently the basis for cloning animals (such as the famous Dolly the sheep), [30] and has been proposed as a possible way to clone humans. Using SCNT in reproductive cloning has proven difficult with limited success. High fetal and neonatal death make the process very inefficient.
Zhong Zhong (Chinese: 中中; pinyin: Zhōng Zhōng, born 27 November 2017) and Hua Hua (Chinese: 华华; pinyin: Huá Huá, born 5 December 2017) are a pair of identical crab-eating macaques (also referred to as cynomolgus monkeys) that were created through somatic cell nuclear transfer (SCNT), the same cloning technique that produced Dolly the sheep in 1996.
