According to research published in the journal Nature, scientists were able to restore circulation to pigs' organs an hour after the animals died, by pumping a synthetic blood substitute through the blood vessels.
Yale researchers developed a device, titled 'OrganEx', that delivers a substance containing compounds that maintain organ function. The development builds on a 2019 breakthrough that saw a team restore a pig's brain functions four hours after death.
Animal testing is cruel, unethical, and dangerous to humans. The National Institute of Health has admitted that 95% of animal tests - which cost US taxpayers more than $15B per year - fail to translate to humans. This money would be better spent on new methods, including the use of microchips that construct postage stamp-size organs from human cells.
This revolutionary treatment is a major breakthrough that could one day save the lives of people who would currently be considered dead. Although there's a long way to go before human application, the practical use of this system could eventually keep organs healthy for longer and provide those in need with transplants.
