An Introduction to Cell Motility and Migration

2023
Cell motility and migration play important roles in both normal biology and in disease. On one hand, migration allows cells to generate complex tissues and organs during development, but on the other hand, the same mechanisms are used by tumor cells to move and spread in a process known as cancer metastasis. One of the primary cellular machineries that make cell movement possible is an intracellular network of myosin and actin molecules, together known as “actomyosin”, which creates a...

Recently available video recording and spatiotemporal mapping (STmap) techniques make it possible to visualize and quantify both propagating and mixing patterns of intestinal motility. The goal of this protocol is to explain the generation and analysis of STmaps using the GastroIntestinal Motility Monitoring (GIMM) system.

Gene Evolution - Fast or Slow?

The genomes of eukaryotes are punctuated by long stretches of sequence which do not code for proteins or RNAs. Although some of these regions do contain crucial regulatory sequences, the vast majority of this DNA serves no known function. Typically, these regions of the genome are the ones in which the fastest change, in evolutionary terms, is observed, because there is typically little to no selection pressure acting on these regions to preserve their sequences. In contrast, regions which code...
FAQs
Several levels of motor control can contribute: sensory input may provide weaker movement-relevant signals, central motor circuits may generate commands less often, neuromodulatory signals may alter behavioral state, or motor neurons may drive muscles with reduced frequency or force. Considering these stages prevents investigators from treating movement speed as a purely muscular outcome and frames it as a nervous-system measure.
Neuromodulatory signals help regulate behavioral state, so their effects can change how frequently and strongly locomotor commands are produced. A reduced movement rate may therefore reflect altered neural state rather than a single failure in the muscles. This distinction makes slow motility useful for examining how state-dependent neural regulation influences locomotion in model organisms.
Tracking the rate of movement provides a behavioral output that can be related to the timing and force of muscle contractions. When that output changes, researchers can examine it alongside neural activity or motor-circuit function to ask whether coordination has been altered. The measure therefore connects observable locomotion with underlying circuit and motor-neuron activity.
Researchers can record an organism’s movement rate, compare it across experimental conditions, and interpret the difference in relation to neural regulation of locomotion. Conditions may involve drugs, injury, aging, or neurological disease. The resulting behavioral comparison offers a practical readout for changes in motor-circuit function without reducing interpretation to muscle performance alone.
It can help identify locomotor changes associated with drugs, injury, aging, and neurological disease. Because the readout reflects the combined influence of sensory input, central motor circuits, neuromodulation, and motor-neuron activity, a change in movement rate can serve as an entry point for investigating which aspects of neural control may have been affected.
Model organisms provide a practical setting in which locomotor behavior can be measured while researchers study the circuits and cells that control it. Slow motility links a visible behavioral outcome to neural activity and motor coordination, allowing experiments to examine how locomotor circuits and cellular mechanisms contribute to behavioral state.
