3D-Printable, Self-Stiffening (4D) and Shape Morphing Hydrogel through Single-Step Orthogonal Crosslinking of Phenolic Biopolymers for Dynamic Tissue Engineering.

Particularly for dynamic, shape-changing, or fibrillar tissues such as muscles and blood vessels, the development of innovative biomaterials is crucial for advancing tissue engineering and regenerative medicine. This study introduces a novel multicomponent hydrogel created from silk fibroin (SF), tyramine-modified hyaluronic acid (HA_Tyr), and tyramine-modified gelatin (G_Tyr). Using an enzymatic orthogonal covalent bonding between phenolic groups, i.

Supercritical CO-Mediated Decellularization of Bovine Spinal Cord Meninges: A Comparative Study for Decellularization Performance.

The extracellular matrix (ECM) of spinal meninge tissue closely resembles the wealthy ECM content of the brain and spinal cord. The ECM is typically acquired through the process of decellularizing tissues. Nevertheless, the decellularization process of the brain and spinal cord is challenging due to their high-fat content, in contrast to the spinal meninges.
