Incorporation of TGF-beta 3 within collagen-hyaluronic acid scaffolds improves their chondrogenic potential.

Incorporation of therapeutics in the form of growth factors within biomaterials can enhance their biofunctionality. Two methods of incorporating transforming growth factor-beta 3 within collagen-hyaluronic acid scaffolds are described, markedly improving mesenchymal stem cell-mediated chondrogenic differentiation and matrix production. Such scaffolds offer control over the release of therapeutics, demonstrating their potential for repair of complex chondral defects requiring additional stimuli
