Abstract: Methods and compositions are described that provide scaffolds for the support of cells. The scaffolds of the present invention have structural uniformity and desirable mechanical properties that make them suitable for a variety of uses, including uses for in vitro tissue regeneration or in vivo tissue or organ replacement. A method is described for controlling three-dimensional structure of the hydrogel/cell constructs under tissue culture environment.
