For the first time, researchers have created lungs in the lab and successfully transplanted them into pigs.

These bioengineered lungs, described online August 1 in Science Translational Medicine, developed healthy blood vessels that allowed pigs to live for several weeks after surgery without medical complications. That’s a significant improvement from previous efforts: Lab-grown lungs implanted in rodents failed within hours, before the lungs could develop the complex blood vessel network necessary for long-term survival.

If the new procedure can be adapted for humans, with bioengineered lungs grown from a patient’s own cells, that could reduce the risk of organ rejection and slash wait times for organ transplants. In the United States, where about 1,500 people currently are on a waiting list for a lung transplant, the average wait is a few months.
