The present disclosure relates generally to the fields of tissue engineering and regenerative medicine. More particularly, the present disclosure generally relates to systems, methods, compositions and kits to rapidly fabricate functionalized three-dimensional tissues from multiple stacks of cell sheets using enzyme-digestible hydrogel substrates as supports for the cell sheets. Methods to generate the multi-layered cell constructs comprise contacting a cell-sheet on one digestable substrate with another cell-sheet on a different digestible substrate, enzymatically digesting with a first enzyme to remove the first substrate and subsequently adding repeating the steps to add another cell-sheet on same digestable substrate to form a multi-layered cell construct as disclosed herein. Additional aspects relate to using the multi-layered cell constructs for therapeutic use, research and in screening assays. |
