On the website of the University of Cambridge appeared evidence of the successful experiment on growing miniature version of the lungs. The development will help in testing new drugs without the involvement of volunteers in the early stages.
In laboratory conditions possible compilation of the most common pathologies. One example is cystic fibrosis, in which to develop lung congestion and mucus to become very viscous. Now there are drugs to treat the disease, but new drugs are developed, and they need to experience.
For these goals to develop "organelles". Groups of cells that meet one of the bodies, simulate the functioning of the liver, lung, brain of the person. In addition, the "mini-organs" help to investigate the disease in the laboratory.
