Modified gellan gum hydrogels for tissue engineering applications

Gellan gum is an anionic linear polysaccharide well known for its use as a multi-functional gelling, stabilising and suspending agent in a variety of foods and personal care products. In this Highlight, we explore the recently established directions for gellan gum hydrogels as materials for applications in tissue engineering. We highlight that modified gellan gum will be well suited for this purpose, providing that a number of remaining challenges are addressed.
