Chemically induced revitalization of damaged hepatocytes for regenerative liver repair.

ABSTRACT: In prolonged liver injury, hepatocytes undergo partial identity loss with decreased regenerative capacity, resulting in liver failure. Here, we identified a five compound (5C) combination that could restore hepatocyte identity and reverse the damage-associated phenotype (e.g., dysfunction, senescence, epithelial to mesenchymal transition, growth arrest, and pro-inflammatory gene expression) in damaged hepatocytes (dHeps) from CCl4-induced mice with chronic liver injury, resembling a direct chemical reprogramming approach. Systemic administration of 5C in mice with chronic liver injury promoted hepatocyte regeneration, improved liver function, and ameliorated liver fibrosis. The hepatocyte-associated transcriptional networks were reestablished with chemical treatment as revealed by motif an
