Abstract

The mammalian liver consists of hexagon-shaped lobules that are radially polarized by blood flow and morphogens. Key liver genes have been shown to be differentially expressed along the lobule axis, a phenomenon termed zonation, but a detailed genome-wide reconstruction of this spatial division of labour has not been achieved. Here we measure the entire transcriptome of thousands of mouse liver cells and infer their lobule coordinates on the basis of a panel of zonated landmark genes, characterized with single-molecule fluorescence in situ hybridization. Using this approach, we obtain the zonation profiles of all liver genes with high spatial resolution. We find that around 50% of liver genes are significantly zonated and uncover abundant non-monotonic profiles that peak at the mid-lobule layers. These include a spatial order of bile acid biosynthesis enzymes that matches their position in the enzymatic cascade. Our approach can facilitate the reconstruction of similar spatial genomic blueprints for other mammalian organs.

  • Hepatocytes are the major parenchymal component of the liver, accounting for approximately 80% of its mass.

    “Hepatocytes, the major parenchymal (epithelial) component of the liver accounting for approximately 80% of its mass”

    From Multimodal decoding of human liver regeneration (2024) · cites this paper as [10]

    The main text (page unavailable) describes liver lobules as composed of layers of hepatocytes, supporting their central role in liver tissue. It does not state that hepatocytes account for approximately 80% of liver mass; a search for “80%” found no such figure. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • These three hepatocyte zones are in agreement with earlier spatial transcriptomics studies.

    “These zones are in agreement with earlier spatial transcriptomics studies6,8.”

    From Single-cell spatial multi-omics and deep learning dissect enhancer-driven gene regulatory networks in liver zonation (2024) · cites this paper as [6]

    The main text and Extended Data Figure 7 report that the paper’s periportal and pericentral expression patterns agree with previous studies. But the paper reconstructs a gradient across nine lobule layers and identifies additional patterns in intermediate layers; it does not establish agreement on three discrete hepatocyte zones. Page numbers are unavailable in our copy. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • These observations are consistent with the classic zonation described in human and mouse liver, supporting the MERFISH measurements.

    “Collectively, these observations are consistent with the classic zonation described in human and mouse liver4,24–26, supporting our MERFISH measurements.”

    From Spatial transcriptomics of healthy and fibrotic human liver at single-cell resolution (2025) · cites this paper as [26]

    The main text describes established liver zonation and reports zonation profiles in mouse liver; it also says those profiles correlated with earlier datasets. This supports the mouse-liver portion of the cited background, but the paper does not establish zonation in human liver. The statement that this supports the citing authors’ MERFISH measurements is their own inference. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • In healthy human liver, hepatocyte zonation reflects a continuous gradient from periportal to pericentral regions rather than distinct zones.

    “While MERFISH allows to us to define these zones, it is also evident through pseudotime analysis, measurement of gene expression across individual lobules, and transcriptional analysis performed across lobules, that zonation reflects a gradient from periportal to pericentral regions rather than distinct zones.”

    From Spatial transcriptomics of healthy and fibrotic human liver at single-cell resolution (2025) · cites this paper as [26]

    The main text reports clear hepatocyte expression gradients and says the findings challenge a binary periportal–pericentral classification. However, it specifies that the zonation profiles studied were from fasted mice, not healthy human liver. The paper therefore supports the gradient interpretation but not the claimed human population. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Wnt target genes and key metabolic enzymes have a zonated expression pattern in pericentral hepatocytes.

    “creating a zonated expression pattern of Wnt target genes and key metabolic enzymes in pericentral hepatocytes (20–22).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
