Ex vivo factor VIII-modified proliferating human hepatocytes therapy for haemophilia A.

ABSTRACT: Ex vivo gene manipulation in human hepatocytes is a promising therapeutic strategy in the treatment of inherited liver diseases. However, a major limitation is the lack of a highly efficient and safe genetic manipulation system for transplantable primary human hepatocytes (PHHs). Here, we reported that proliferating human hepatocytes (ProliHHs) cultured in vitro showed high susceptibility to lentivirus-mediated genetic modification and maintained cellular phenotypes after lentiviral infection. Human factor VIII expression was introduced through F8-Lentivirus-mediated transduction of ProliHHs followed by xenotransplantation into immunocompromised haemophilia A mice. We demonstrated that these F8-modified ProliHHs could effectively repopulate the mouse liver, resulting in therapeutic benefit
