Collective responses of animals are generally controlled by complex biological mechanisms and in Caenorhabditis eleganscollective dynamics are purely controlled by physical parameters such as oxygen penetration and bacterial diffusion.
Genetic, biochemistry and modeling approaches reveal elements of a Turing-type reaction-diffusion system to control pattern formation in differentiating cyanobacterial filaments.
A mathematical modelling approach to understanding zebrafish stripe pattern formation exemplifies a biological rule-set sufficient to generate wild-type and a diverse range of mutant patterns.
Mechanical interactions between bacterial species with different motility characteristics play an important role in spatial-temporal dynamics of multi-species bacterial colonies and can lead to formation of complex patterns.
SHH signaling acts through FOXF1/2 transcription factors and antagonizes BMP signaling to specify oral fate and pattern the oral-aboral axis of the mandibular arch to ensure proper formation of jaws.
The changes in shape of iridophores that underlie adult colour pattern formation in zebrafish depend on the levels of Tight Junction Protein 1a in these cells.
Theoretical analysis and in vitro reconstitution of a biological reaction-diffusion system identify key functional motifs as well as underlying principles and enable rebuilding pattern formation in a modular fashion.
Propagation, speed and shapes of genetic waves of expression during development can be modeled by a simple interplay between two transcriptional modules (dynamic/static), which explains robustness and precision of patterning.
Transient cell-cell contact of eukaryotic cells, called contact following locomotion, causes cell density segregation, and its high-density region traveled as a band within the disordered background.
