Currently in the US, there are close to 115,000 patients in need of a lifesaving organ transplant.
Using gene editing technology, it's now possible to exquisitely create a human-transplantable organ that can be safely grown in pigs.
The second, and specific to the organs from the pig, is a virus called the porcine endogenous retrovirus (PERV), which is benign to the pig but can be transmitted into humans.
Imagine a world where patients who suffer from liver failure can be saved with a new liver without having to wait for a donation or another human to die.
