Abstract

The ability to observe biological processes continuously, instead of at discrete time points, holds great promise for the study of tissue regeneration. Ideally, single cells would be followed continuously within large tissue volumes (such as organs) over long periods of time. Technical limitations, however, preclude such studies. But, recently, there have been improvements in imaging technologies and biologically compatible labelling agents. Together with new insights into the molecular characteristics of stem cells, which are ultimately responsible for the regenerative potential of all tissues, researchers are now much closer to applying single-cell imaging approaches to research into regeneration and its clinical applications.
