cover: To grow new tissues or organs such as human eardrums, bioengineers can create a polymer scaffold resembling the body’s own extracellular tissue matrix. This example shows collagen-producing fibroblast cells that latched onto a mesh of ultrafine, 830-nm-wide polymer fibers (yellow); fluorescence microscopy reveals the cells’ nuclei (blue) and protein filaments (red). To read about progress toward creating an artificial eardrum, turn to page 14. (Microscopy image courtesy of Jürgen Groll, University of Würzburg; anatomy sketch courtesy of FCIT.)
