Why are pigs chosen for xenotransplantation?

Transgenic pigs are promising donor organisms for xenotransplantation as they share many anatomical and physiological characteristics with humans. In addition, transgenic strategies have been developed to reduce the potential risk of infections by endogenous porcine retroviruses.

Which species is suitable for xenotransplantation?

Xenotransplantation (xenos = from the Greek meaning “foreign”) is one of the possibilities: For these transplantations, tissues or organs from phylogenetically distant species (for example from a pig) are transferred to primates (rhesus monkeys, baboons, later humans).

  • It reduces opportunities on the black market for organ donations.
  • It has the potential to open up new areas of research.
  • How does xenotransplantation work?

    Xenotransplantation is any procedure that involves the transplantation, implantation or infusion into a human recipient of either (a) live cells, tissues, or organs from a nonhuman animal source, or (b) human body fluids, cells, tissues or organs that have had ex vivo contact with live nonhuman animal cells, tissues or organs.
