In this week’s Medical Discovery News with UTMB’s David Niesel and Norbert Herzog: Imagine that a patient needs an organ, like an airway to the lungs called a trachea. A scientist harvests some of the patient’s cells and attaches them to a scaffold the proper shape and size for the tube. The cells and scaffolds are placed into a tissue reactor and — ta da! — in a week or two there is an organ ready for the surgeon to transplant into the patient. While it sounds like a chapter from “Brave New World,” this science fiction scenario is a growing reality.
