Objective To understand the latest development in lineage tracing techniques and their applications in the study of liver regeneration mechanisms. Method A review of domestic and international literature on the application of lineage tracing techniques in liver regeneration was conducted. Results A variety of more reliable and advanced lineage tracing techniques had been developed, such as single-cell RNA sequencing, DNA barcode technology, etc., providing powerful tools for a deeper understanding of the mechanisms of liver regeneration. The marked progress had been made in identifying the origins of liver regeneration cells, identifying liver regeneration areas, and studying the mechanisms of liver regeneration after injury. The lineage tracing techniques help to understand the position and function of different types of liver cells within the liver structure, revealing the regenerative potential and contribution of different subpopulations of liver cells. Moreover, these techniques had supported the phenomenon of transdifferentiation between the hepatocytes and the bile duct cells under chronic liver injury conditions, aiding in understanding the specific roles of key signaling pathways in liver regeneration, such as Wnt/β-catenin, Hippo/YAP, and Notch signaling pathways.Conclusions Although lineage tracing techniques have made marked progress in liver regeneration research, liver regeneration is a complex and important physiological process, and the technique still has limitations, such as challenges in marker specificity, longer research cycles and higher costs, potential limitations in translating from animal models to human clinical applications, inability to solve all questions about liver regeneration mechanisms, and ethical and legal issues. Therefore, more in-depth and comprehensive research is still needed to reveal more details of liver regeneration mechanism.
