Implication

Preclinical study reveals zone-specific hepatocyte proliferation during liver maintenance and repair in mice, suggesting distinct cell pools drive organ regeneration.

Key Points

Develop an unbiased genetic tool to continuously record proliferation across entire cell populations and map hepatocyte division patterns during liver maintenance and injury repair.
Constructed ProTracer, a dual-recombinase genetic lineage-recording system engineered to track proliferation continuously across whole cell populations.
Applied the ProTracer system in mouse models to measure spatial hepatocyte division and perform clonal analyses during homeostasis, injury repair, and regrowth.
ProTracer revealed enriched, zone-specific hepatocyte proliferation across distinct regions of the mouse liver during normal homeostasis, repair, and tissue regrowth.
Clonal analysis confirmed that the vast majority of ProTracer-labeled hepatocytes had successfully undergone cell division.
