cell lineage tracing

Cell lineage tracing is a technique used to track the origin and development of individual cells over time. By marking specific cells with unique identifiers, scientists can observe how these cells divide, differentiate, and contribute to various tissues as an organism grows or repairs itself. This method helps researchers understand the complex pathways of cell development, revealing how different cell types arise from common ancestors and how tissues are formed and maintained. It’s an essential tool in developmental biology, regenerative medicine, and cancer research, providing insights into normal growth and disease processes.
