Already home to the world’s first cloned dog using somatic cell-transfer technique, China is now the world’s first country to clone a dog using gene editing. Sinogene, a Beijing-based biotech company, announced the achievemen­t on July 5, Science and Technology reported. China is the second country to master somatic cell-cloning technology, after South Korea. Dog cloning has always been regarded by scientists as the most difficult, compared with more easily cloned sheep, mice, cows and pigs. Poor oocyte quality and the asynchrono­us reproducti­on cycle of the surrogate mother and the cloned embryo limit the applicatio­n of the technology.
