Abstract

The mammalian liver is composed of repeating hexagonal units termed lobules. Spatially resolved single-cell transcriptomics revealed that about half of hepatocyte genes are differentially expressed across the lobule, yet technical limitations impeded reconstructing similar global spatial maps of other hepatocyte features. Here, we show how zonated surface markers can be used to sort hepatocytes from defined lobule zones with high spatial resolution. We apply transcriptomics, miRNA array measurements and mass spectrometry proteomics to reconstruct spatial atlases of multiple zonated features. We demonstrate that protein zonation largely overlaps with mRNA zonation, with the periportal HNF4α as an exception. We identify zonation of miRNAs such as miR-122, and inverse zonation of miRNAs and their hepatocyte target genes, highlighting potential regulation of protein levels through zonated mRNA degradation. Among the targets we find the pericentral Wnt receptors Fzd7 and Fzd8 and the periportal Wnt inhibitors Tcf7l1 and Ctnnbip1. Our approach facilitates reconstructing spatial atlases of multiple cellular features in the liver and other structured tissues.

  • Blood flow from the periportal to the perivenous zones along the lobular axis creates spatial gradients of oxygen, metabolites, and nutrients, which benefit hepatocytes and other cells.

    “Blood flow from the periportal to the perivenous zones along the lobular axis creates spatial gradients of oxygen, metabolites, and nutrients, which benefit hepatocytes and other cells (Tsukada et al., 2013;Ben-Moshe and Itzkovitz, 2019).”

    From Fast formation and maturation enhancement of human liver organoids using a liver-organoid-on-a-chip (2024) · cites this paper as Ben-Moshe and Itzkovitz, 2019

    The Introduction (page not specified) says blood flows from portal nodes toward central veins, generating gradients of oxygen and nutrients, and links the graded environment to hepatocyte zonation. It names hormones rather than metabolites as a blood-flow-generated gradient, and does not say these gradients benefit other cell types. (LLM, conf=0.86)

  • The liver is a spatially and functionally heterogeneous organ that contains branches of the hepatic portal vein, hepatic artery, and biliary tree across its lobules.

    “The liver is a spatially and functionally heterogeneous organ that contains branches of the hepatic portal vein, hepatic artery, and biliary tree across its lobules (Ben-Moshe et al., 2019;Inverso et al., 2021).”

    From Fast formation and maturation enhancement of human liver organoids using a liver-organoid-on-a-chip (2024) · cites this paper as Ben-Moshe et al., 2019

    The Introduction (page unavailable) describes lobules and spatial heterogeneity in hepatocyte gene expression, while the Discussion describes functional differences between zones. The paper mentions blood flowing from portal nodes but does not describe branches of the hepatic portal vein, hepatic artery, and biliary tree across lobules. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Tcf7l1 and Tbx3 expression is zonated in the adult mouse liver.

    “while it has been previously reported that Tcf7l1 and Tbx3 expression is zonated in the adult mouse liver43,53”

    From Single-cell spatial multi-omics and deep learning dissect enhancer-driven gene regulatory networks in liver zonation (2024) · cites this paper as [43]

    The Results section (“Regulation of Wnt signaling components by miRNA”) reports that Tcf7l1 is periportally zonated in hepatocytes, supporting that part of the claim. Our copy does not report zonated Tbx3 expression; a search for “Tbx3” found no passage addressing it. No page number was available in the indexed copy. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Expression of perivenous markers was significantly elevated close to the outlet where oxygenation is lower.

    “In contrast, expression of perivenous markers was significantly elevated close to the outlet where oxygenation is lower.”

    From 3D microperfusion of mesoscale human microphysiological liver models improves functionality and recapitulates hepatic zonation (2023) · cites this paper as [33]

    The Results section ('Spatial sorting enables isolating bulk hepatocyte populations') identifies CD73 as a pericentral marker, and 'Zonation patterns of the hepatocyte proteome' reports significant protein zonation, including pericentrally enriched pathways. The Introduction describes blood flowing from portal nodes toward draining central veins and generating an oxygen gradient, but our copy does not explicitly establish that oxygenation is lower near the outlet or report a significance test for the perivenous markers as a group. Page numbers were not available in our copy. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • Close to the inlet, where oxygen concentrations are highest, increased levels of the periportal marker proteins ARG1, BAAT, PYGL, FBP1 and ASL were observed.

    “Close to the inlet, where oxygen concentrations are highest, we observed increased levels of the periportal marker proteins ARG1, BAAT, PYGL, FBP1 and ASL ( Fig. 6 a).”

    From 3D microperfusion of mesoscale human microphysiological liver models improves functionality and recapitulates hepatic zonation (2023) · cites this paper as [33]

    The Results section on hepatocyte proteome zonation reports periportally enriched proteins and pathways, supporting the general periportal-marker context. Our copy does not identify ARG1, BAAT, PYGL, FBP1 and ASL as a set of periportal protein markers; the citing authors’ observation of increased levels near the inlet is their own finding, not one established by this source. (LLM, conf=0.78)

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.
