New paper published on internal dynamics of bacterial aggregates

Finally, our work on how cells move within bacterial colonies forming due to type IV pili is published in Scientific Reports. Identical cells of a colony are more motile at the surface of the colony than in the bulk. With the help of theoretical modelling, we find that this behavior emerges due to a gradient in the pili dynamics and the resulting forces. We also discover that the gradient of cell motility and forces correlate with a gene expression gradient, pointing towards early differentiation.
