Live cell imaging is a research technique that allows scientists to observe and track the behavior of living cells in real time. This technique usually involves the use of fluorescent dyes or proteins that can be used to label specific cellular structures or processes, allowing researchers to visualize and study various cellular events such as cell division, migration, communication, and response to stimuli. Live cell imaging is valuable for studying dynamic processes within cells and for monitoring the effects of drugs or genetic modifications on cell behavior. This technique is commonly used in cell biology, developmental biology, neuroscience, and drug discovery research.
