Partial Resurrection: Pigs' Organs Revived After Death
Written on
Chapter 1: Introduction to Organ Revival
Research into organ revival has advanced significantly, leading to exciting possibilities in transplantation. While scientists are not claiming to achieve immortality, their innovative methods may enhance the supply of natural organs available for transplant.
Scientists at Yale University, led by Dr. Nenad Sestan, have focused on reviving the brains of deceased mammals, particularly pigs. They have successfully restored neuronal metabolism within hours post-mortem using a blood substitute.
Section 1.1: The Breakthrough Experiment
On August 3, the team published their findings in Nature, detailing a novel system called OrganEx. This apparatus connects to the circulatory system of a pig that has been dead for an hour, circulating a fluid designed to maintain tissue vitality and metabolic balance. This system could provide organs with a remarkably extended preservation period.
Subsection 1.1.1: Historical Context
The scientific community first learned of Dr. Sestan's research on April 17, 2019, when he revealed results from the BrainEx device, which revived brain tissue from pigs four hours after their death.
Section 1.2: Comparing Techniques
In this recent study, the researchers utilized an enhanced version of their previous device and compared it with the traditional ECMO (Extra Corporeal Membrane Oxygenation) system. ECMO temporarily replaces heart and lung functions but carries risks that can lead to further complications and hasten death.
Chapter 2: Results and Implications
The results from the Yale experiment suggest that the OrganEx system outperforms ECMO. Organs supported by OrganEx demonstrated better tissue integrity and fewer signs of internal bleeding and swelling. Moreover, the oxygenated blood substitute spurred cellular repair processes, hinting at a form of immortality for internal organs.
This video discusses the partial revival of pig organs and the implications of such research on organ transplantation.
Furthermore, the authors emphasize that while further investigation is essential to assess the machine's full potential, the goal is not to bring the deceased back to life but to improve the availability of natural organs for transplantation, which relies on deceased donors.
This video highlights the stunning new research where scientists revived pig organs after death, raising ethical questions about the definition of death.
The researchers clarify that their work is not intended to provoke accusations of attempting to resurrect life functions post-mortem. In their initial study, precautions were taken to prevent the reactivation of consciousness in the pigs by adding substances to inhibit neuronal activity. Nonetheless, this research has sparked discussions about the boundaries of death and whether we need to rethink its definition.
Despite three years passing since the initial findings, there has been little public discourse regarding similar experiments.
