Live-cell dynamics

Definition

Live-cell dynamics refers to the study of biological processes in living cells over time, capturing the movements and interactions of cellular components. This concept is crucial for understanding cellular behavior, as it enables researchers to visualize events such as cell migration, division, and intracellular transport in real-time. Advanced microscopy techniques allow scientists to monitor these processes without significantly disturbing the living cells.
