By Jon Schiller, ISRAEL21c While modern medicine has made leaps and bounds in the field of tissue and organ reconstruction over the years, it is still limited by one major drawback: Human beings don’t have spare parts. If a car-accident survivor needs a reconstructed jaw, for instance, surgeons must build it from a piece of the patient’s fibula bone and the surrounding soft tissue and blood vessels, in a procedure known as autografting. Autografting takes a heavy toll on the body and can often lead to medical complications. Prof. Shulamit Levenberg’s bioengineering team at the Technion-Israel Institute of Technology has introduced a better way.
