Xenotransplantation-reflections on the bioethics.

Area of Science:

• Transplantation Medicine
• Bioethics
• Medical Technology

Background:

• China faces a critical shortage of human organs for transplantation, with only 23.90% of patients receiving transplants in 2019.
• This scarcity significantly restricts the application of organ transplantation technology in China.
• There is a growing societal and medical imperative to address the demand-supply gap in organ transplantation.

Purpose of the Study:

• To explore xenotransplantation as a viable solution for the human organ shortage.
• To examine the scientific and ethical challenges associated with animal-to-human organ transplantation.
• To inform China's approach to xenotransplantation clinical trials.

Main Methods:

• Review of international efforts in xenotransplantation research.
• Analysis of scientific and ethical considerations in using animal organs for human recipients.
• Examination of recent clinical trials in xenotransplantation.

Main Results:

• The first clinical trial of a transgenic pig heart transplant into a human recipient occurred in January 2021.
• This trial has generated significant interest and enthusiasm in the field of xenotransplantation.
• Xenotransplantation research continues to address scientific and ethical hurdles.

Conclusions:

• Xenotransplantation presents a potential avenue to alleviate the global organ donor deficit.
• The trend highlights the urgent need to address organ scarcity and high transplantation costs worldwide.
• China must proactively navigate the scientific, public health, and ethical dimensions of xenotransplantation clinical trials.
