Human liver progenitor-like cells-derived extracellular vesicles promote liver regeneration during acute liver failure.

ABSTRACT: Hepatocyte-derived liver progenitor-like cells (HepLPCs) exhibit a remarkable capacity to support liver function by detoxifying ammonia, promoting native liver regeneration, and suppressing inflammation, which leads to improvements in the recovery and survival of animals with acute liver failure (ALF). However, the mechanism through which HepLPCs promote liver regeneration is unclear. Here, we isolated HepLPC-derived extracellular vesicles (HepLPC-EVs) from conditioned media and performed microRNA sequencing analysis. Our results showed HepLPC-EVs promoted liver regeneration in mice with carbon tetrachloride or acetaminophen induced ALF. Cell cycle progression and proliferation of primary human hepatocytes were promoted after coculture with HepLPC-EVs. Exosomal miRNA sequencing confirmed t
