Lineage Tracing Reveals the Bipotency of SOX9+ Hepatocytes during Liver Regeneration
Open accessAbstract
Elucidation of the role of different cell lineages in the liver could offer avenues to drive liver regeneration. Previous studies showed that SOX9 + hepatocytes can differentiate into ductal cells after liver injuries. It is unclear whether SOX9 + hepatocytes are uni- or bipotent progenitors at a single-cell level during liver injury. Here, we developed a genetic tracing system to delineate the lineage potential of SOX9 + hepatocytes during liver homeostasis and regeneration. Fate-mapping data showed that these SOX9 + hepatocytes respond specifically to different liver injuries, with some contributing to a substantial number of ductal cells. Clonal analysis demonstrated that a single SOX9 + hepatocyte gives rise to both hepatocytes and ductal cells after liver injury. This study provides direct evidence that SOX9 + hepatocytes can serve as bipotent progenitors after liver injury, producing both hepatocytes and ductal cells for liver repair and regeneration.

YAP activation in liver regeneration reprograms a subset of periportal hepatocytes into SOX9+ progenitor-like cells that can give rise to both cholangiocytes and hepatocytes.
“YAP activation in liver regeneration has been shown to reprogram a subset of periportal hepatocytes into SOX9+ progenitor-like cells (PLCs) that can give rise to both cholangiocytes and hepatocytes (51, 52).”
From Senescent hepatic stellate cells promote liver regeneration through IL-6 and ligands of CXCR2 (2022) · cites this paper as [51]
The Results identify SOX9+ cells among periportal hepatocytes, and the Discussion reports that a single SOX9+ hepatocyte can give rise to both biliary epithelial cells (cholangiocytes) and hepatocytes after injury. But the Discussion says whether Hippo-YAP signaling is activated in these cells to regulate their bipotency remains to be investigated; this paper does not establish that YAP activation reprograms them.

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.
