Researchers have successfully transplanted bioengineered lungs into pigs, they report in Science Translational Medicine. After 2 weeks, every pig that received the transplant grew blood vessels and tissue needed for blood circulation in their transplanted lungs, according to The Scientist. Although the lungs showed signs of development, they were unable to develop enough to fully provide the pigs with oxygen independently. Despite the setback, researchers believe bioengineered lung transplants will be possible for humans within 10 years.
