<p>In a new study published today in <em>Cell</em>, researchers from Prof. Ido Amit's lab at the Weizmann Institute of Science have managed for the first time to develop a method for tracking and measuring changes over time on in single cells inside the body. The method, called Zman-seq (from the Hebrew word <em>zman</em>, for “time”), consists of labeling cells with different time stamps and tracking them in healthy or pathological tissue. Using this cellular time machine, researchers can get to know the cells’ history and how long each cell had stayed in the tissue, ultimately achieving an understanding of the molecular and cellular temporal changes that had taken place within that tissue.</p>
