GROOVE 1 (IMAGE) Rice University Caption Rice University research scientist Maryam Elizondo holds a 3D-printed scaffold engraved with grooves for the deposition of live cells for implantation. The scaffold facilitates the growth of new tissues as it degrades. By protecting cells in grooves along the printed lines, Rice researchers designed the scaffold to enable different tissue-type layers within one scaffold.
