Abstract

Hepatocytes operate in highly structured repeating anatomical units termed liver lobules. Blood flow along the lobule radial axis creates gradients of oxygen, nutrients and hormones, which, together with morphogenetic fields, give rise to a highly variable microenvironment. In line with this spatial variability, key liver functions are expressed non-uniformly across the lobules, a phenomenon termed zonation. Technologies based on single-cell transcriptomics have constructed a global spatial map of hepatocyte gene expression in mice revealing that ~50% of hepatocyte genes are expressed in a zonated manner. This broad spatial heterogeneity suggests that hepatocytes in different lobule zones might have not only different gene expression profiles but also distinct epigenetic features, regenerative capacities, susceptibilities to damage and other functional aspects. Here, we present genomic approaches for studying liver zonation, describe the principles of liver zonation and discuss the intrinsic and extrinsic factors that dictate zonation patterns. We also explore the challenges and solutions for obtaining zonation maps of liver non-parenchymal cells. These approaches facilitate global characterization of liver function with high spatial resolution along physiological and pathological timescales.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Hepatocyte function and metabolism varies along the portocentral axis of the liver lobule, a phenomenon known as zonation.

    “In the mammalian liver, hepatocytes exhibit diverse metabolic and functional profiles based on their location within the liver lobule.”
  • Blood flow from the portal vein to the central vein in each liver lobule creates a gradient of nutrients, oxygen, hormones and morphogens, resulting in a highly variable environmental axis.

    “In each liver lobule, blood flows from the portal vein to the central vein, creating a gradient of nutrients, oxygen, hormones and morphogens that results in a highly variable environmental axis5 (Fig. 1a).”
  • During the first 3 weeks of life, the liver transitions from an immature to a mature state as hepatocytes exit the cell cycle, become polyploid, and organize within a zonated lobular structure.

    “During this period, the liver transitions from an immature to a mature state as hepatocytes exit the cell cycle, become polyploid, and organize within a zonated lobular structure (Jungermann and Kietzmann 1996; Ben-Moshe and Itzkovitz 2019; Donne et al. 2020).”

    From ESRP2–microRNA-122 axis promotes the postnatal onset of liver polyploidization and maturation (2025) · cites this paper as Ben-Moshe and Itzkovitz 2019

  • Hepatocyte function varies depending on position along the porto-central axis, as hepatocytes are exposed to different microenvironments, a phenomenon known as zonation.

    “Hepatocyte function varies depending on the position along this porto-central axis, as they are exposed to different microenvironments, a phenomenon known as zonation7.”
  • Periportal hepatocytes are more involved in gluconeogenesis and beta-oxidation, while pericentral hepatocytes are more involved in glycolysis, lipogenesis, and detoxification.

    “For example, periportal hepatocytes are more involved in gluconeogenesis and beta-oxidation, while pericentral hepatocytes are more involved in glycolysis, lipogenesis, and detoxification7.”

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.
