Abstract

Transdifferentiation is a complete and stable change in cell identity that serves as an alternative to stem-cell-mediated organ regeneration. In adult mammals, findings of transdifferentiation have been limited to the replenishment of cells lost from preexisting structures, in the presence of a fully developed scaffold and niche 1. Here we show that transdifferentiation of hepatocytes in the mouse liver can build a structure that failed to form in development-the biliary system in a mouse model that mimics the hepatic phenotype of human Alagille syndrome (ALGS)2. In these mice, hepatocytes convert into mature cholangiocytes and form bile ducts that are effective in draining bile and persist after the cholestatic liver injury is reversed, consistent with transdifferentiation. These findings redefine hepatocyte plasticity, which appeared to be limited to metaplasia, that is, incomplete and transient biliary differentiation as an adaptation to cell injury, based on previous studies in mice with a fully developed biliary system 3-6. In contrast to bile duct development 7-9, we show that de novo bile duct formation by hepatocyte transdifferentiation is independent of NOTCH signalling. We identify TGFβ signalling as the driver of this compensatory mechanism and show that it is active in some patients with ALGS. Furthermore, we show that TGFβ signalling can be targeted to enhance the formation of the biliary system from hepatocytes, and that the transdifferentiation-inducing signals and remodelling capacity of the bile-duct-deficient liver can be harnessed with transplanted hepatocytes. Our results define the regenerative potential of mammalian transdifferentiation and reveal opportunities for the treatment of ALGS and other cholestatic liver diseases.

  • Lineage-tracing studies in animal models have confirmed that hepatocytes contribute to bile duct remodeling following cholangiocyte injury.

    “Lineage-tracing studies in animal models have confirmed that hepatocytes contribute to bile duct remodeling following cholangiocyte injury10,43–48”

    From HBO1 functions as an epigenetic barrier to hepatocyte plasticity and reprogramming during liver injury (2025) · cites this paper as [43]

    The Abstract (page unavailable) reports hepatocyte fate tracing in mice: after DDC-induced cholestatic liver injury, hepatocytes gave rise to cells in reactive ductules. It also reports that hepatocytes formed functional peripheral bile ducts in mice lacking those ducts. These findings support a hepatocyte contribution to biliary repair, but the paper does not establish that the reported remodeling followed cholangiocyte injury specifically. (LLM, conf=0.83)

  • Reprogramming of differentiated cells into progenitor-like cells is an important injury-repair paradigm independent of adult stem cells in various epithelial tissues in mammals.

    “The reprogramming of differentiated cells into progenitor-like cells has recently been discovered as an important injury-repair paradigm independent of adult stem cells in a variety of epithelial tissues in mammals, 1 such as the lung, 2 intestine, 3 pancreas, 4 and liver.5,6”

    From Kupffer-cell-derived IL-6 is repurposed for hepatocyte dedifferentiation via activating progenitor genes from injury-specific enhancers (2023) · cites this paper as [6]

    The Abstract (page not provided) describes transdifferentiation as an alternative to stem-cell-mediated regeneration and reports hepatocytes forming mature cholangiocytes during liver injury. It also describes similar cell plasticity in other mammalian epithelia. It does not establish the claimed transition into progenitor-like cells; its demonstrated endpoint is another differentiated cell type. (LLM, conf=0.83)

  • Hepatocytes display remarkable plasticity and under some conditions can transdifferentiate into BECs.

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.
