This study analysed the role of VEGFR-2 in liver fibrosis and its regeneration process. Materials and Methods: We administered 50 mg/kg to 300 mg/kg thioacetamide (TAA) to 9-week-old male mice intraperitoneally for 17 weeks. We measured the levels of VEGFR-2 protein and identified the location of cells that specifically express VEGFR-2. Results: VEGFR-2 is rarely expressed in normal hepatocytes. However, high VEGFR-2 expression in liver sinusoidal endothelial cells was noted in the TAA group. Conversely, the group that experienced regeneration from liver fibrosis showed significantly higher VEGFR-2 expression in the nucleus of hepatocytes compared to the other groups. Conclusion: VEGFR-2 plays a pivotal role in the nucleus of hepatocytes during liver regeneration and VEGFR-2 may be closely related to cell division. Therefore, VEGFR-2 may be a new therapeutic target for liver regeneration.
