Every organism exists in relationship to its ancestors, descendants, and cousins, and the path between any two individuals can be traced. The same is true of cells within organisms—each of the trillions of cells in the human body is produced through successive divisions from a fertilized egg, and can all be related to one another through a cellular family tree. In simpler organisms such as the worm C. elegans, this cellular family tree has been fully mapped, but the cellular family tree of a human is many times larger and more complex. /news/2025-07-tool-tumor-cell-history-reveal.html Cell & Microbiology Molecular & Computational biology Fri, 25 Jul 2025 11:10:19 EDT news672660181 In the same vein as weather forecast models that predict developing storms, researchers have now developed a method to predict the cell activity in tissues over time.
