Scientists manage to ‘resurrect’ organs from dead pigs


Mexico.- Yale University scientists have managed to ‘resurrect’ organs from dead pigs, a finding that could help prolong the health of human organs.

According to the scientists, this new advance was able to restore blood circulation and other cellular functions in the organs of dead pigs.

With this, experts hope that the number of organs available for transplants can be increased.

Just as they hope to give doctors more time to save the lives of their patients, if this new technique is applied to ‘resurrect’ organs in people.



As explained by the scientists of the prestigious university, their research was based on being able to understand what happens in the organs after death.

In answering this, they pointed out that minutes after the heart stops beating in pigs, various biochemicals begin to destroy the cells and organs of the body in the absence of blood flow, oxygen and nutrients.

Given this, the scientists say that this permanent cell failure does not have to happen so fast, which led them to use their technique called OrganEx.

Blood technique used to administer a cell-protecting fluid specially designed for organs and tissues.

With which the scientists restored blood circulation and other cellular functions in pigs an hour after their death.

According to David Andrijevic, a research scientist in neuroscience at Yale School of Medicine and co-senior author of the study, it was possible to ‘resurrect’ organs from dead pigs because “not all cells die.”

“It’s a process where you can intervene, stop and restore some mobile function.”

Said new scientific advance, it is a new technology that consists of a perfusion device similar to heart-lung machines.

With which it is possible to make the heart and lungs work during surgery, in addition to using an experimental fluid that contains compounds that can promote cellular health and suppress inflammation throughout the pig’s body.

So the scientists conducted tests using pigs that had been slaughtered an hour earlier at a local hatchery, then treated with OrganEx an hour after death.

And six hours after receiving the OrganEx treatment, the scientists found that key cellular functions were active in many areas of the pigs’ bodies.

Functions where the heart, liver and kidneys were included, which managed to restore part of their organic function.

Because evidence of electrical activity in the heart was found, which retained the ability to contract.

“We were also able to restore circulation throughout the body, which surprised us.”

Also, the scientists were able to detect involuntary and spontaneous muscle movements in areas such as the head and neck, which were described as evidence of the recovery of some motor functions.

“If we could restore certain cellular functions in the dead brain, an organ known to be more susceptible to ischemia (inadequate blood supply), we hypothesized that something similar could be achieved in other vital transplantable organs as well.”
