Tissue Engineering: Bio‐Origami Hydrogel Scaffolds Composed of Photocrosslinked PEG Bilayers (Adv. Healthcare Mater. 8/2013)

A new biofabrication approach to synthesize cell-laden hydrogels in anatomically relevant three dimensional geometries is described by D. H. Gracias and co-workers on page 1142. The inside cover shows the highly parallel and spontaneous self-assembly of photopatterned two dimensional cell-laden hydrogels into simultaneously curved and patterned microstructures.
