Advances and applications of genetically modified pig models in biomedical and agricultural field.

Compared with rodents, pigs are closer to humans in terms of anatomy, metabolism and physiology, so they are ideal animal models of human diseases and xenotransplantation donors. In addition, as one of the most important livestock in China, pigs are closely related to our lives in terms of breeding improvement, disease prevention and animal welfare. In this review, we mainly summarize the research progress and future application of genetically modified pig models in the fields of xenotransplantation, molecular breeding and human disease models.
