Scientists in Germany have developed a miniature lung which could be used to test new lung cancer treatments in the future.
The 3D model lung is based on human lung cancer cells. A machine helps it to ‘breathe’ and pumps a fluid nutrient through its blood vessels. Factors including the speed and depth of the model lung’s breathing can also be tailored using the machine.
The researchers believe that their artificial lung could provide an accurate way of testing how new cancer treatments affect the body. They also hope that it could be used to learn more about how cancer in one organ spreads to other areas.
