The effect of G-MDSCs depletion on the gene expression profile of hepatocytes at different times following 70% hepatectomy


ABSTRACT: Liver regeneration following resection is a complex process relying on coordinated pathways and cell types in the remnant organ. Myeloid-Derived Suppressor Cells (MDSCs) have a role in liver regeneration-related angiogenesis but their influence on hepatocyte proliferation and immune modulation during liver regeneration is unclear. We examined the transcriptional response of regenerating liver hepatocytes after major resection in mice with CD11b+Ly6G+ MDSCs (G-MDSCs) depletion using RNA sequencing. Global gene expression profiling of regenerating hepatocytes upon G-MDSC depletion revealed disrupted transcriptional progression from day one to day two after major liver resection. Key genes and pathways related to hepatocyte proliferation and immune response were differentially expressed upon MDSC depletion. This study provides evidence that MDSCs contribute to early liver regeneration by promoting hepatocyte proliferation and modulating the intra-liver immune response. These findings illuminate the multifaceted role of MDSCs in liver regeneration.
