These tiny interwoven fibers make up the 3-D fabric "scaffold" into which a strong, pliable hydrogel is integrated and infiltrated with stem cells, forming a framework for growing cartilage. The resulting composite material is tough, flexible and formable and has excellent frictional properties.
It mimics both the strength and suppleness of native cartilage.Image credit: Frank Moutos, Orthopaedic Research Laboratories, Duke University, and Farshid Guilak, Professor of Orthopaedic Surgery and Mechanical Engineering and Materials Science, Duke University
