摘要: Background/Aims: Liver is a vital organ and retains its regeneration capability throughout adulthood, which requires contributions from different cell populations, including liver precursors intrahepatic stem cells. To overcome the mortality of hepatic progenitors (iHPs) in vitro, we aim to establish reversibly immortalized progenitor cells mouse embryonic liver. Methods Results: Using retroviral system stably express SV40 T antigen flanked with Cre/LoxP sites, repertoire iHP clones varied differentiation potential. The maintain long-term proliferative activity levels markers (Pou5f1/Oct4 Dlk) hepatocyte (AFP, Alb ApoB). Five representative hepatic/pancreatic transcription factors HNF3α/Foxa1, HNF3β/Foxa2, HNF4α/MODY1. Dexamethasone shown promote expression AFP TAT, along ICG-uptake glycogen storage functions clones. Cre-mediated removal reverses When are subcutaneously implanted athymic nude mice, no tumor formation observed for up 8 weeks. Conclusions: We demonstrate that established stable, reversible, non-tumorigenic progenitor-like cells, should be valuable studying organogenesis, metabolic regulations, lineage-specific differentiation.
