The hepatic extracellular matrix: I. Components and distribution in normal liver

Martinez-Hernandez, Antonio, Amenta, Peter S.·1993·Virchows Archiv A Pathological Anatomy and Histopathology

Abstract

The unique nature of the hepatic extracellular matrix (ECM) is predicated by the special configuration of the space of Disse. Whereas other epithelial organs have two basement membranes (BM) and a substantial ECM interposed between endothelial and epithelial cells, the liver lobule has no BM and only an attenuated ECM, consisting mostly of fibronectin, some collagen type I, and minor quantities of types III, IV, V, and VI. This configuration, together with the abundant fenestrations and gaps of the sinusoidal endothelial cells, seems ideally suited to facilitate the rapid bidirectional exchange of macromolecules normally taking place between plasma and hepatocytes. During organogenesis, the liver anlage is vascularized by continuous capillaries with BM, but by day 13.5 of development (in the rat) the vessels in the immediate proximity of hepatocytes become fenestrated, lacking specialized junctions and BM, suggesting that the hepatocytes produce signals capable of modulating the endothelial phenotype. In regeneration, hepatocyte proliferation precedes vascular proliferation resulting in the formation of hepatocyte clusters that, temporarily, lack sinusoids. Eventually, vascular proliferation follows and the normal hepatocyte-vascular relationships are restored. During this period laminin synthesis by Ito cells is prominent. As soon as hepatocytes become stable, secretion of the sinusoid phenotype-maintaining factors resumes and laminin synthesis and secretion terminates. The…

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • Collagen type I is present all over the liver lobule, basement membrane formation is only observed in portal and central spaces, and collagen type IV can also be found in the space of Disse.

    “Collagen type I is present all over the liver lobule, while the formation of a basement membrane (BM) is only observed in the portal and central spaces. However, collagen type IV, a typical BM element, can also be found in the space of Disse (Martinez-Hernandez and Amenta, 1993[26]).”
  • In vivo, the distribution of ECM components varies between different parts of the liver acinus.

    “In vivo, the distribution of ECM components varies between the different parts of the liver acinus, the smallest organizational unit of the liver (Godoy et al., 2013[15]; Martinez-Hernandez and Amenta, 1993[26]).”
  • Culturing hepatocytes on either collagen type I or Matrigel alone does not sufficiently reflect the ECM composition of the liver.

    “Culturing hepatocytes on either collagen type I or Matrigel alone, does not sufficiently reflect the ECM composition of the liver (Benton et al., 2014[4]; Hughes et al., 2010[19]; Martinez-Hernandez and Amenta, 1993[26]).”

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.
