摘要： Background Mice with humanized livers are important models to study drug toxicology testing, development of hepatitis virus treatments, and hepatocyte transplantation therapy. However, the huge difference between mouse and human in size and anatomy limited the application of humanized mice in investigating human diseases. Therefore, it is urgent to construct humanized livers in pigs to precisely investigate hepatocyte regeneration and human hepatocyte therapy. CRISPR/Cas9 system and somatic cell cloning technology were used to generate two pig models with FAH deficiency and exhibiting severe immunodeficiency (FAH/RAG1 and FAH/RAG1/IL2RG deficiency). Human primary hepatocytes were then successfully transplanted into the FG pig model and constructed two pigs with human liver. Results The constructed FAH/RAG1/IL2RG triple-knockout pig models were characterized by chronic liver injury and severe immunodeficiency. Importantly, the FG pigs transplanted with primary human hepatocytes produced human albumin in a time dependent manner as early as 1 week after transplantation. Furthermore, the colonization of human hepatocytes was confirmed by immunochemistry staining. Conclusions We successfully generated pig models with severe immunodeficiency that could construct human liver tissues.
