Growing organs in the lab has become a reality in the past couple of years as scientists have learned more about stem cells and how they mature to become the cells that make up organs and other body parts. Windpipes, for example, have been successfully grown and implanted into human patients, and just last spring, a team of researchers at Massachusetts General Hospital in Boston successfully implanted lab grown kidneys into rats. In this new effort, the researchers have been focusing on growing one of the most complicated organs in the human body—the lungs.
Nichols explained the procedure in simple terms. Lungs from two deceased juveniles were obtained. The first lung was stripped of all of its cells leaving just a scaffolding of elastin and collagen. Healthy cells were then taken from the second lung and applied to the scaffolding.
