Last Updated: 2024/11/10, Famous Chinese biologist Yang Xiangzhong has worked with scientific research departments in Taiwan to produce the world's first cloned pig with human factor 9 and porcine lactoferrin, the University of Connecticut announced. The results of this study are expected to be used in the treatment of hemophilia. According to Yang Xiangzhong, a professor at the University of Connecticut, the study was conducted under extreme secrecy by a research team he chaired in cooperation with Taiwan's Institute of Animal Science and Technology. The first cloned pig was held at the Institute of Animal Science in Taiwan on February 15 this year.

Famous Chinese biologist Yang Xiangzhong has worked with scientific research departments in Taiwan to produce the world's first cloned pig with human factor 9 and porcine lactoferrin, the University of Connecticut announced. The results of this study are expected to be used in the treatment of hemophilia. According to Yang Xiangzhong, a professor at the University of Connecticut, the study was conducted under extreme secrecy by a research team he chaired in cooperation with Taiwan's Institute of Animal Science and Technology. The first cloned pig was born at the Institute of Animal Science in Taiwan on February 15 this year, followed by the second and third cloned pigs, which are currently in good health.

The somatic cells of the cloned pigs came from the ears of a double-genetically transferred sow, Xinhua reported. The milk of this sow can produce ninth clotting factor and porcine lactoferrin. The cause of human hemophilia is the lack of factor 9. The milk from cloned pigs is expected to be used in the treatment of hemophilia after biotechnology treatment. On the other hand, porcine lactoferrin has the function of inhibiting bacteria and enhancing immunity, can resist inflammation and help growth, and help to prevent porcine dysentery, thus improving the breeding rate of pigs. Yang Xiangzhong explained that whether the cloned offspring of this dual-gene transfer pig will produce these two proteins in its milk like donor sows remains to be further studied and observed. Yang Xiangzhong said that his cloning team spent nearly three years on cloning transgenic pigs, and finally developed an efficient cloning method.
