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.
