Gelatin is the denatured form of collagen. Gelatin possesses several advantages for tissue-engineering application: they attract fibroblasts, are non-immunogenic, easy to manipulate and boost the formation of epithelium. There are three types of gelatin-based scaffolds:
* Gelatin-oxidized dextran matrix
* Gelatin-chitosan-oxidized dextran matrix
* Gelatin-glucan matrix
* Gelatin-hyaluronate matrix
* Gelatin-chitosan hyaluronic acid matrix.
Glucan is a polysaccharide with antibacterial, antiviral and anticoagulant properties. Hyaluronic acid is added to improve the biological and mechanical properties of the matrix.
