Clonal tracing of Sox9+ liver progenitors in mouse oval cell injury
Branden D. Tarlow, Milton J. Finegold, Markus Grompe – 22 February 2014 – Proliferating ducts, termed “oval cells,” have long been thought to be bipotential, that is, produce both biliary ducts and hepatocytes during chronic liver injury. The precursor to oval cells is considered to be a facultative liver stem cell (LSC). Recent lineage tracing experiments indicated that the LSC is SRY‐related HMG box transcription factor 9 postive (Sox9+) and can replace the bulk of hepatocyte mass in several settings.
