3D bioprinting lobule-like hepatorganoids with induced vascularization for orthotopic implantation.

ABSTRACT: Orthotopic implantation in vivo is the ultimate target of tissue-engineering organoids research, aiming to achieve sustaining survival after implantation. However, the limited representation of a complex microenvironment in implanted accepter hampers a comprehensive understanding of long-term maintenance of tissue-engineering organoids, especially in liver. In this research, we developed a 3D bioprinting method using gelatin methacryloyl (GelMA) hydrogel to fabricate lobule-like hepatorganoids, which faithfully mimic the structure of hepatic lobules with lower level of hypoxia (lobule vs 60°, 90°, control; 0.4880 vs 1.009, 0.6778, 0.8704; p < 0.01), high secretion of albumin (lobule vs 60°, 90°, control; 13.47 vs 12.39, 12.65, 10.08 mg/L; p < 0.01) and urea (lobule vs 60°, 90°, cont
