ABSTRACT
The developmental history of a cell fundamentally defines its identity and function. Recent advances in cell lineage tracing now enable high-resolution reconstruction of cellular ancestries in vivo, illuminating how lineage dictates fate in health and disease. This Review highlights recently developed tools, ranging from refined recombinase systems to advanced synthetic and natural barcoding approaches, that facilitate the investigation of pathological lineage programs in cancer, cardiovascular disease and aging. Moving forward, integrating permanent lineage records with single-cell multi-omics promises to provide a unified framework to decode how a cell's past shapes its present state and future potential, heralding a new era for precision medicine.
