Scientists Claim to Bring Dead Human Eye Cells Back to Life

irreversible cessation of circulatory, respiratory and brain activity is what death is defined as.

The first line of the new study says that they woke up light-sensitive cells from human organ donors five hours after death.

The researchers from Switzerland and the US published their findings in the journal Nature yesterday.

Moran Eye Center's Fatima Abbas said that they were able to wake up the cells in the human macula, which is the part of the retina responsible for our central vision.

In a first round of experiments, the researchers were able to revive photoreceptors, but they were not able to communicate with other cells in the retina.

The team created a method to keep the cells oxygenated for longer periods of time, because they found a lack of oxygen to be the main problem. After at least one of the other qualifications for death already happened, they extended the period of time for the retina and neuron cells.

The team is pretty confident that they will be able to reverse some types of blindness.

Frans Vinberg, co-author of the study, said that the scientific community can now study human vision in ways that are not possible with laboratory animals.

The press release suggests that extending the shelf life of donor organs and giving retinas their ability to sense light back is aival.

The irreversible cessation of circulatory, respiratory or brain activity is what the team defines as death.

When it comes to organ donation or even when death is declared, it could be considered reversing death if some of the functions of the photoreceptors are returned.

That may not fall within the scope of the study.

There is more on immortality, and it is very dangerous.
