Ductular reactions in human liver: Diversity at the interface

Abstract

Interest in hepatic ductular reactions (DRs) has risen in recent years because of a greater appreciation of their potential roles in regeneration, fibrogenesis, and carcinogenesis. However, confusion exists because there is significant, but often unappreciated diversity at the tissue, cellular, and subcellular levels in DRs of different diseases and stages of disease. DRs are encountered in virtually all liver disorders in which there is organ-wide liver damage and cell loss, but are also present in focal lesions such as focal nodular hyperplasia and adenoma. Moreover, diverse DR phenotypes can be present within any single disease entity, and are shaped by the etiology and evolution of the disease. Although much remains to be clarified, recent studies suggest that the diversity of appearances of the DRs are likely to reflect the differing signals at the anatomic, cellular, and molecular levels driving the proliferative response. These appear to determine the relative proportions of transit-amplifying cells, the degree of hepatocytic or cholangiocytic differentiation, and their relationships with stromal, vascular, and inflammatory components. The molecular signaling pathways governing these regenerative fate decisions closely replicate those found in human and other vertebrate embryos and more generally in stem cell niches throughout the body. Like the latter, complex interactions with matrix as well as mesenchymal and inflammatory cells, vessels, and innervation are likely to be of fundamental importance. Embracing systems/tissue biological approaches to exploring DRs, in addition to more traditional cellular and molecular biological techniques, will further enhance our understanding and, thereby, we believe potentiate new therapeutic possibilities.

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.
