Miniature Lung Grown by Scientists to Test Cancer Drugs

This tiny lung, no bigger than a sugar cube, was developed by scientists to test medications that could be used in the fight against lung cancer. Researchers from Germany's Fraunhofer Institute took malignant tumour cells derived from a cancer patient and grew them on a scaffold of connective tissue to form the miniature lung. The device is then attached to a bioreactor which circulates nutrients through the systems blood vessels and simulates breathing.
