Abstract
Disclosed herein are biodegradable hydrogel scaffolds for use in tissue engineering. The hydrogel scaffolds are composed of synthetic terpolymers complexed with polyvinyl alcohol (PVA), which facilitate cell-sheet and tissue growth. In the presence of a monosaccharide, the PVA-hydrogel is dissolved and cell-sheets are released for harvesting. Further disclosed herein are methods for producing PVA hydrogels which support tissue growth. Tissue engineering applications and methods are also disclosed.
