A major breakthrough in the US research team, successfully recovering dead pig brain cells

Experts pointed out on the 17th that scientists succeeded in restoring the function of pig brain cells after the death of pigs. It is expected to help patients suffering from heart disease and stroke in the future and solve the mystery of brain trauma.

Agence France-Presse reported that experiments published in the journal Nature found that pig brains can restore blood flow and cellular function even after a few hours of death.

In the brains of humans and large mammals, cells that are critical to neurological function begin to degrade as blood supply decreases, and this process has long been considered impossible to change.

The National Institutes of Health (NIH) Human Brain Research Initiative team used 32 pig brains to implement this federally sponsored research project. Each pig was slaughtered for food and discarded. After 4 hours of no blood or glucose flow, it was used for experiments.

Next, the team injected the blood-like fluid into the organ through the development of an extracorporeal pulsatile-perfusion system, allowing the pig brain to become a hydrate for 6 hours.

The results of the experiment were shocking, and the brains that were infused with artificial blood restored basic cellular functions. In addition to their vascular structure recovery, the team also observed a brief resuscitation of some activities including neuronal synapses and immune responses.

Nenad Sestan, a researcher at Yale University, said: “We are surprised that the structure of the brain (the brain) is so well maintained. We have also observed a decrease in cell death, which is very exciting and hopeful. Sethden further said: “The main finding of the study is that the cell death process in the brain is longer than we thought.”

The research team also emphasized that they did not find “higher-order functional operations,” such as the presence of radio signals associated with awareness in the brain of recovery. The results of the study show that scientists may not correctly assess the patient’s ability to self-repair after the brain is determined to die.

However, this research has also led to experts asking for deeper philosophical and ethical issues.

Nita Farahany, a professor of law and philosophy at Duke University, points out that the study “shakes long-standing assumptions about what makes animals or humans alive.”

Dominic Wilkinson, a professor of medical ethics at the University of Oxford, said: “Research reminds us that “death” is not an event, it is more like a necessary process.”
