Financial aspects of organ procurement from deceased donors in the USA-Relevance to xenotransplantation.

abstract：BACKGROUND:Manipulating the pig genome to increase compatibility with human biology may facilitate the clinical application of xenotransplantation. Genetic modifications to pig cells have been made by sequential recombination in fetal fibroblasts and liver-derived cells followed by cross-breeding or somatic cell nuclea...
