Abstract:
Isolated porcine hepatocytes, isolated populations of such hepatocytes and methods for using the hepatocytes to treat subjects with disorders characterized by insufficient liver function are described. The porcine hepatocytes can be either hepatocytes isolated from adult, immature, or embryonic swine. The porcine hepatocytes can be modified to be suitable for transplantation into a xenogeneic subject, for example, by altering an antigen (e. g. , an MHC class I antigen) on the cell surface which is capable of stimulating an immune response against the cell in the subject (e. g. , by contact with an anti-MHC class I antibody, or a fragment or derivative thereof). The isolated porcine hepatocytes of the invention can be used to treat disorders characterized by insufficient liver function by administering the hepatocytes to a subject having such a disorder.
