  • Gellan gum spongy-like hydrogel, its preparation and biomedical applications thereof
    Patent number: 9579417
    Abstract: The present application discloses cell-adhesive gellan gum spongy-like hydrogels that are able to entrap/encapsulate adherent cells, which spread within the material, maintaining their phenotype and remaining viable and proliferative. The methodology used to obtain these materials involves hydrogel preparation, freezing, freeze-drying and re-hydration with a saline solution with cells and with/without bioactive molecules. No pre and/or post functionalization of the spongy-like hydrogels with cell adhesive features, as used for other hydrogels, is used. The cell adhesive character of these materials, not observed in hydrogels, is in part explained by their physical properties, between sponges and hydrogels, dissimilar from the precursor hydrogels. The physical properties that are mainly different are the morphology, microstructure, water content, and mechanical performance.
