問題詳情

   Tiny tubes emerge from a small transparent block, pumping imperceptible amounts offluid and air to and fro. It looks like a Fox’s Glacier Mint has been plugged into a life supportmachine, but this humble chunk of see-through silicone is a model organ that couldrevolutionize the pharmaceutical industry, reducing the need for animal testing and speedingup the development of new drugs.   Meet the Lung-on-a-chip, a __26__ of the biological processes inside the human lung,developed by the Wyss Institute for Biologically Inspired Engineering at HarvardUniversity – and now crowned Design of the Year by London’s Design Museum.   __27__ living human cells, the “organs-on-chips” mimic the tissue structures and  mechanical motions of human organs, promising to __28__ drug discovery, decreasedevelopment costs and potentially __29__ a future of personalized medicine.   “This is the epitome of design innovation,” says Paola Antonelli, design curator at NewYork’s Museum of Modern Art. “Removing some of the pitfalls of human and animal testingmeans, theoretically, that drug trials could be conducted faster and their viable results __30__more quickly.”   “The organs-on-chips allow us to see biological mechanisms and behaviors that no oneknew existed before,” says Don Ingber, founding director of the Wyss Institute. “We nowhave a window on the molecular-scale activities going on in human organs, including thingsthat happen in human cells that don’t occur in animals. Most drug companies get completelydifferent results in dogs, cats, mice and humans, but now they will be able to test the specificeffects of drugs with greater accuracy and speed.”
