Elastic hydrogel
View Patent ↗The present invention relates to hydrogels and to the use of hydrogels for repair or restoration of tissue. In particular, the hydrogels of the present invention can be used for the repair or restoration of cardiac tissue.
1. A hydrogel comprising an acrylated tropoelastin, wherein at least one amine group of the tropoelastin is attached to an acrylate group.
2. A hydrogel comprising an acrylated tropoelastin formed by the process of treating a tropoelastin with a compound comprising an acrylate group in conditions for attaching the acrylate group of the compound to an amine of the tropoelastin.
3. A hydrogel comprising a cross-linked tropoelastin, the cross-linked tropoelastin comprising:
a plurality of tropoelastin monomers or multimers; and
a linker in the form of a compound having an acrylate group, wherein the acrylate group of the compound is attached to an amine group of the tropoelastin for cross-linking the monomers or multimers.
4. A hydrogel comprising an acrylated tropoelastin, wherein about 30% to about 50% of the lysine residues of the tropoelastin are attached to an acrylate group.
5. A tissue-engineered construct comprising a hydrogel of claim 1 .
6. A tissue-engineered construct comprising a hydrogel of claim 2 .
7. A tissue-engineered construct comprising a hydrogel of claim 3 .
8. A tissue-engineered construct comprising a hydrogel of claim 4 .
9. A device, support or scaffold comprising a hydrogel according to claim 1 .
10. A device, support or scaffold comprising a hydrogel according to claim 2 .
11. A device, support or scaffold comprising a hydrogel according to claim 3 .
12. A device, support or scaffold comprising a hydrogel according to claim 4 .
