Yield stress gel helps build complex biological constructs

A team of engineers from Penn State University (PA, USA) has developed a novel method employing ‘yield stress’ gel for producing complex 3D structures with a goal to develop tissues for bone and cartilage replacement. Previously it has been difficult to bioprint structures with the thin bioprinting films available, so the team hopes this novel approach will help to provide a fully-three dimensional shape to biological constructs. “The reason why this is important is that the current cell aggregate bioprinting techniques can’t make complicated configurations and is mostly in 2D and 3D thin films or simple configurations. If we want…
