Live-cell imaging is a technique that allows scientists to observe living cells in real-time. By using specialized microscopes and fluorescent dyes, researchers can visualize cellular processes, such as movement, division, and interactions, without harming the cells. This method provides valuable insights into how cells function in their natural environment. This imaging technique is crucial for various fields, including cell biology, neuroscience, and cancer research. It helps scientists understand disease mechanisms, track the effects of drugs, and study cellular responses to different stimuli. Overall, live-cell imaging enhances our knowledge of biological processes at the cellular level.
