3D-printed lungs made with living cells could help to improve lung disease prevention and treatment—and potentially one day offer a lab-grown option for use in organ transplants. University of Saskatchewan scientists developed a 3D lung tissue model to provide a better environment for studying medicines and diseases like tuberculosis, COVID-19, asthma, COPD and pulmonary fibrosis. Currently, researchers typically use 2D and animal models to study lung diseases like tuberculosis, but these are
