Implication

Narrative review demonstrates how three-dimensional architecture governs metabolic zonation in the liver, highlighting pathways for bioengineered tissue rescue.

Key Points

To review multi-scale three-dimensional structural organization of the liver, examining how spatial architecture and biochemical gradients dictate hepatocyte specialization, disease patterns, and regenerative capacity.
Surveyed structural frameworks describing liver architecture, including classical lobules, portal lobules, metabolic acini, and modular polyhedral human tissue reconstructions.
Evaluated multi-scale imaging and analytical modalities including vascular corrosion casting, micro-CT, light-sheet microscopy, single-cell transcriptomics, and spatial transcriptomics.
Approximately 50% of the hepatocyte transcriptome exhibits spatial zonation along the portal-to-central lobular axis, coordinated by a Wnt signaling gradient from central vein endothelium.
Zonal specialization directly determines pathological susceptibility, leading to zone-specific patterns of drug toxicity, steatosis, and hepatic fibrosis.
Liver regeneration recapitulates developmental programs, providing structural and molecular blueprints for synthetic biology and bioengineered tissue replacement.
