What is Live-Cell Imaging?

Besides the structural organization of cells or organs, dynamic processes are a major contributor to a functioning biological entity. Naturally, these processes can be best observed in living cells with non-invasive techniques like optical methods, collectively called “live-cell imaging” methods. Live-cell imaging covers all techniques where live cells are observed with microscopes – from the observation of embryogenesis with stereo microscopes, via cell growth studies with compound microscopes, until studies of physiological states of cells or cellular transport using fluorescent dyes or proteins. Although being highly demanding for both, experimenter and equipment (e.g. imaging systems, climate control), live-cell imaging techniques deliver results that are indispensable for present-day research.
