Scientists from Yale University in the USA were able to partially restore the viability of the organs of a pig an hour after the animal died.. According to the BBC, this is a breakthrough that could further increase the number of organs available to people for transplants and give doctors more time to save lives..

The scientists' study is also changing the idea of \u200b\u200bwhat happens between life and death.. Experts say the discovery is 'really outstanding' and 'incredibly important'.

When the heart stops beating, the body lacks the oxygen and other nutrients it needs to survive.. Organs grow in size, blood vessels collapse, and cells begin to die..

It was thought that this cell death happened once and for all, but now scientists have managed to repair some of the damage in the organs of animals that were dead within an hour..

“We can restore some cell function in many vital organs that should have been dead.. These cells function a few hours after they shouldn't,” said Prof. Nenad Sestan..

In 2019, scientists managed to do something similar, but with the brain of a pig. Now a technology called OrganEx has been adapted to work with the whole body..

Researchers use synthetic blood to carry oxygen throughout the body. Such blood does not clot, so it can move through the collapsing blood vessels of the pig.. In addition, scientists introduced a cocktail of 13 compounds to interrupt chemical processes that end in cell death, as well as a device to pump blood throughout the body to mimic a beating heart..

The experiments, the results of which were published in the journal Nature, involved 100 pigs.. Conducting such experiments was approved on the basis of ethical considerations..

Researchers put animals into deep sleep and stopped their hearts. After they were in this state for more than an hour, they were connected to the OrganEx system and given a restorative cocktail for six hours.. At the same time, throughout the experiment, the animals continued to be given anesthesia..

Six hours later, scientists dissected the pigs and found that organs such as the heart, liver and kidneys partially recovered and were able to regain some functionality..

The electrical activity in the heart was restored, the heart muscle could contract, but the organs did not function at the same level as in life.

Previously, scientists from the Weizmann Institute in Israel were the first in the world to create " At the same time, the researchers did not need sperm, eggs and the fertilization process..
