• Researchers Develop 3D Printed Lab-Grown Ear Cartilage March 2
Additional Context
Researchers from ETH Zurich, the Friedrich Miescher Institute in Basel, and the Cantonal Hospital of Lucerne have successfully produced elastic ear cartilage in laboratory conditions using human cartilage cells. The engineered tissue demonstrated mechanical properties similar to natural cartilage and retained its shape and elasticity after six weeks when tested in animal models. The research builds on decades of work attempting to create replacement ears for patients who have lost them due to accidents or congenital conditions.
The development addresses a significant medical need, as microtia affects approximately four in every 10,000 children, causing congenital malformations of the outer ear. Current treatment involves reconstructing ears using the patient’s rib cartilage, a painful pro
