Research in pigs shakes up what we know about dying- By Katie Hunt (CNN) / Aug 3, 2022
(CNN) Researchers at Yale University say they have been able to restore blood circulation and other cellular functions in pigs a full hour after the animals’ deaths, suggesting that cells don’t die as quickly as scientists had assumed.
With more research, the cutting-edge technique could someday potentially help preserve human organs for longer, allowing more people to receive transplants.
The researchers used a system they developed called OrganEx which enables oxygen to be recirculated throughout a dead pig’s body, preserving cells and some organs after a cardiac arrest.
“These cells are functioning hours after they should not be,” said Dr. Nenad Sestan, the Harvey and Kate Cushing Professor of Neuroscience and professor of comparative medicine, genetics and psychiatry at Yale, who led the study.
