Visible light-mediated cross-linking of injectable gellan gum hydrogels embedding human chondrocytes

This is the authors' abstract. We don't add key points for this paper.

Gellan gum, a polysaccharide with structural similarities to glycosaminoglycans, is gaining attention in cartilage tissue engineering. It can be chemically modified with methacrylic moieties to produce a photo-crosslinkable formulation, called methacrylated gellan gum (GGMA), envisaging the injection and the in situ cross-linking through light on the cartilage surface.
