We have developed a video-rate tracking microscope system that can record and quantify C. elegans behavior at high resolution and high speeds. We have also developed computational methods to reduce the dimensionality of the worm images to a fundamental set of measurements that completely describe the shape of the worm.

To study Myxococcus xanthus swarm behavior, we have designed a time-lapse microcinematography protocol that can be modified for different assays. It employs standard growth conditions adapted for microscopy, and yields reproducible results by the use of inexpensive, reusable silicone gaskets. We have used this method to quantify multicellular chemotaxis.

Described here is a novel automated experimental system that offers an alternative to the three-chamber test and also solves several caveats. This system supplies multiple behavioral parameters that enable rigorous analysis of small rodent behavioral dynamics during the social preference and social novelty preference tests.
FAQs
Useful measurements include cell migration, division, shape changes, and cell-cell contacts. Examining these features together shows whether cells act independently or display coordinated behavior. Tracking changes over time also helps connect visible cellular actions with signals in the surrounding tissue, providing a basis for interpreting how local events contribute to larger patterns of tissue organization.
The approach compares the behavior of individual cells with the behavior of the group. Researchers can follow separate migration patterns, divisions, and shape changes while also examining whether cells maintain contacts or move in a coordinated manner. This distinction helps clarify how collective movement emerges from cellular activities rather than treating the entire group as a single undifferentiated unit.
Cell-cell contacts provide information about how neighboring cells influence organization and movement, while signals from surrounding tissue help explain why behavior changes over time. Considering both factors connects measurable events, such as altered shape or migration, with their biological context. This is important for identifying mechanisms that link local interactions to tissue-level dynamics.
A typical workflow combines time-lapse microscopy with image analysis. Researchers first record cellular behavior across successive time points, then use the resulting images to follow individual cells and quantify migration, division, shape changes, and contacts. The measurements can then be related to surrounding tissue signals or compared across experimental conditions to evaluate changes in multicellular behavior.
Researchers can use the method when they need to determine how cellular behavior differs between experimental conditions. Comparing migration, division, shape, or cell-cell contacts may reveal changes in coordination and organization that are not apparent from a single observation. Such comparisons support studies of tissue dynamics and help clarify which conditions are associated with particular multicellular responses.
Following cellular behavior over time helps researchers relate coordinated activity to tissue formation and repair, while also identifying behavior associated with disease-related changes. The resulting observations can clarify mechanisms of tissue dynamics and improve models of how tissues change. In biology, this provides a way to connect cellular-scale measurements with broader developmental, restorative, or pathological processes.
