Decellularized Extracellular Matrix Composite Hydrogel Bioinks for the Development of 3D Bioprinted Head and Neck In Vitro Tumor Models

To overcome the limitation characteristic of pure ECM hydrogels, researchers presented a composite material containing alginate, a seaweed-derived polysaccharide, and gelatin, denatured collagen, as rheological modifiers which imparted mechanical integrity to the biologically active decellularized ECM
