Portal fibroblasts: Underappreciated mediators of biliary fibrosis†

Open access
Dranoff, Jonathan A., Wells, Rebecca G.·2010·Hepatology

Abstract

UNLABELLED: Portal fibroblasts are an important yet often overlooked nonparenchymal cell population in the liver. They are distinct from hepatic stellate cells, yet like stellate cells differentiate in the setting of chronic injury to fibrogenic myofibroblasts, playing an important role in collagen production in the fibrotic liver. Portal fibroblasts (PFs) are located adjacent to bile duct epithelia and thus play a particularly significant role in biliary fibrosis. New data suggest that they may also have key functions independent of fibrogenesis. This review addresses the definition and characteristics of PFs as well as their signaling pathways, interactions with the biliary epithelium, and contributions to liver pathobiology. CONCLUSION: PFs are an important and multifunctional nonparenchymal cell population in need of further study.

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

  • PFs are a key myofibroblast precursor in cholestatic liver injury, and PF populations expand in murine models of biliary injury, expressing high levels of fibrillar collagen at single-cell resolution.

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.
