Hydrogels based on chitosan in tissue regeneration: How do they work? A mini review

The repair of tissue defects after injury is of significant clinical and research importance. A variety of chitosan‐based hydrogels have been investigated and applied to address this problem. By using different synthetic methods, the hydrogels exhibit distinct physical properties, including porosity, adhesion, and stiffness. These properties are considered important factors affecting cell proliferation and tissue regeneration. Meanwhile, drug...
