Preparation and performance study of strontium-carboxymethyl chitosan/silk fibroin/gelatin composite cartilage scaffolds

Key Points

• This study aims to develop a scaffold that mimics the natural extracellular matrix to support cartilage regeneration.
• Preparation of strontium-carboxymethyl chitosan/silk fibroin/gelatin composite scaffold.
• Assessment of scaffold structure and properties.
• Evaluation of strontium ion release rate and tissue response.
• The scaffold effectively mimics the natural extracellular matrix structure.
• Sustained release of strontium ions was achieved.
• The microenvironment fosters cartilage tissue regeneration.
