Sejttörzsszámok, also known as cell lineage numbers or cell tracking numbers, are unique identifiers assigned to individual cells within a population undergoing study. These numbers are crucial for tracking the progeny of a specific cell over time. In biological research, particularly in developmental biology, stem cell research, and cancer biology, understanding how cells divide and differentiate is paramount. Sejttörzsszámok allow researchers to follow the complete history of a single cell and all its descendants, creating a detailed map of cell fate.

The assignment of these numbers can be achieved through various methods. One common approach involves a system of sequential numbering where each new daughter cell receives a unique identifier derived from its parent cell. For instance, if a parent cell is assigned number 1, its two daughter cells might be designated 1.1 and 1.2, and their offspring further subdivided (e.g., 1.1.1, 1.1.2). More advanced techniques utilize fluorescent proteins or genetic barcodes that are faithfully inherited through cell division, allowing for automated tracking and analysis of large cell populations.

The utility of sejttörzsszámok extends to determining cell division rates, identifying specific cell types based on their lineage, and understanding the dynamics of tissue formation and regeneration. By meticulously recording the lineage of each cell, researchers can reconstruct complex developmental processes and identify critical decision points in a cell's life. This granular level of detail is invaluable for uncovering the fundamental principles of cell biology and for developing targeted therapeutic strategies for diseases involving abnormal cell behavior.
