Xenotransplantation
Xenotransplantation[edit | edit source]
Introduction[edit | edit source]
Xenotransplantation is a medical procedure involving the transplantation of tissues or whole organs from one species to another. This advanced field of transplantation medicine aims to address the critical shortage of human organs available for transplant.

Definition and Scope[edit | edit source]
Xenotransplantation covers a range of procedures:
- Transplantation of cells, tissues, or organs from a non-human animal species to a human recipient.
- Cross-species transplantation within non-human species.
Historical Overview[edit | edit source]
Xenotransplantation is not a new concept; it has historical roots with experiments dating back to the 17th century. However, significant scientific interest in xenotransplantation as a feasible medical procedure began in the 20th century.
Potential and Challenges[edit | edit source]
The potential of xenotransplantation is immense, especially considering the shortage of human donors. However, it faces several challenges:
- Immunological Rejection: The human immune system may aggressively reject the transplanted organ.
- Risk of Zoonoses: The possibility of transmitting animal diseases to humans.
- Ethical Considerations: Concerns regarding the use of animals for human transplantation.
Recent Advances[edit | edit source]
Recent advances in genetics and immunology, such as the development of genetically modified pigs to reduce organ rejection, have brought renewed interest and hope in xenotransplantation.
Regulatory and Ethical Aspects[edit | edit source]
Xenotransplantation raises significant regulatory and ethical issues. Regulatory bodies across the world are continually updating guidelines to address the safety, ethical, and welfare concerns related to the use of animals in transplantation.
