Time-lapse microscopy

Definition

Time-lapse microscopy is a technique that captures a sequence of images over a period of time, allowing researchers to observe dynamic processes in living cells or organisms. This method provides insights into cellular behavior, development, and interactions by visualizing changes that occur over time, which is essential for understanding cell lineage and fate mapping during developmental biology.
