Hepatocyte-derived extracellular vesicles regulate liver regeneration through a negative feedback mechanism.

ABSTRACT: While significant progress has been made in understanding various aspects of liver regeneration, the molecular mechanisms responsible for the initiation and termination of cell proliferation in the liver following massive tissue loss or injury of liver remain unknown. As it was previously shown, the loss of liver mass affects putative hepatocyte-specific mitogenic inhibitors in the blood. Although the presence of these putative inhibitors regulating precise liver regeneration has been described in numerous publications, they have never been identified. Extracellular vesicles (EVs) are nano-sized, membrane-limited structures secreted by cells into the extracellular space. Their proposed role is stable intercellular carriers of proteins and RNAs, predominantly micro-RNA, from secreted to rec
