Three-dimensional (3D) bioprinting provides a unique platform to reconstruct biomimetic liver tissues through spatially orchestrated cellular and extracellular matrix integration. Here, we developed 3D bioprinted hepatorganoids derived from human induced hepatocytes (hiHeps), which faithfully recapitulate the native lobular zonation crucial for spatially segregated metabolic functions in vivo. 3D bioprinted hiHeps hepatorganoids (3DP-HHO) exhibited markedly enhanced metabolic performance, including improved glucose and lipid regulation and elevated albumin synthesis, highlighting their potential as advanced liver models. The hepatorganoids demonstrated robust regenerative potential, which reversed chronic liver fibrosis (CLF) by resolving pathological collagen deposition, rescued acute liver failure (ALF) through rapid functional compensation, and accelerated liver regeneration in partial hepatectomy models by stimulating endogenous hepatocyte proliferation. Preclinical validation of post-hepatectomy liver failure (PHLF) model revealed that the implantation of 3DP-HHO significantly improved survival outcomes and promoted liver regeneration, compared to controls. In the future, by integrating patient-specific cells with regulable 3D microenvironments, our platform will achieve superior functional integration and regenerative efficacy over conventional approaches. This work establishes a paradigm for bioengineered liver grafts that actively drive tissue repair and regeneration. As a scalable and physiologically relevant approach, these bioprinted hepatic units pioneer a transformative strategy in regenerative hepatology, addressing critical challenges in treating liver failure and post-resection recovery while illuminating microenvironmental factors essential for organ-level regeneration.
