The successful replication of the intricate architecture of human tissues remains a major challenge in the biomedical area. Three-dimensional (3D) bioprinting has emerged as a promising approach for the biofabrication of living tissue analogues, taking advantage of the use of adequate bioinks and printing methodologies. Here, a hydrogel bioink based on gelatin (Gel) and nanofibrillated cellulose (NFC), cross-linked with genipin, was developed for the 3D extrusion-based bioprinting of hepatocarcinoma cells (HepG2). This formulation combines the biological characteristics of Gel with the exceptional mechanical and rheological attributes of NFC. Gel/NFC ink formulations with different Gel/NFC mass compositions, viz., 90:10, 80:20, 70:30,…
