Three-Dimensional Photopatterning of Hydrogels Containing Living Cells

The development of a photopatterning technique that allows localized photoencapsulation of live mammalian cells to control the tissue architecture and the combination of microfabrication approaches with photopolymerizable biomaterials will have implications in tissue engineering, elucidating fundamental structure–function relationships of tissues, and formation of immobilized cell arrays for biotechnological applications.
