Zonated mechanosensing by PIEZO1 controls liver regeneration
Abstract
The liver exhibits a marked regenerative capacity organized through distinct zones, yet how tissue mechanics coordinate zonated proliferation remains elusive. We reveal that mechanical cues critically contribute to mouse liver regeneration in a highly region-specific manner through sensing by a subpopulation of mid-lobular hepatocytes, which are characterized by dipeptidyl peptidase-4 (DPP4) expression and represent the key proliferative pool of hepatocytes. PIEZO1 is a primary mechanosensor enriched in zone 2 DPP4 + hepatocytes that integrates biomechanical cues to drive liver regrowth by insulin-like growth factor binding protein 2 (IGFBP2). Genetic disruption of PIEZO1 restrains hepatocyte proliferation and compromises liver regeneration, whereas zonated PIEZO1 gain of function enhances proliferation and accelerates recovery. These findings reveal that DPP4 + mechanosensitive hepatocytes orchestrate liver regrowth through PIEZO1-mediated mechanosensing, establishing a link between tissue mechanics and liver regeneration.

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.
