The loss or failure of human tissue and organs is one of the most frequent and costly problems in health care. Treatments most often focus on surgical reconstruction and transplantation, or replacing damaged tissue or a diseased organ with a healthy specimen from another body. In this video segment focusing on science/STEM learning, your students will learn how tissue engineering combines the principles of engineering and life sciences to developing biological substitutes that are designed to restore, maintain or improve tissue and organ function.
With the help of PBS’s “Design Squad,” students will hear about the work of Howard Pryor, a tissue engineer and doctor at Massachusetts General Hospital. Dr. Pryor demonstrates a device he is working on to replace diseased livers. He explains the challenges of artificially engineering a human organ, including getting blood to flow through a device for processing just as it would through a liver. He also details the design process. WATCH: http://to.pbs.org/1zFIoHO
