Phase-field modeling of border cell cluster migration in Drosophila

Fig 5

Schematic representation of Tangential Interface Migration (TIM) force.

The border cell cluster (BC, green) is surrounded by nurse cells (NC, pink), the regions of contact between the border cell cluster and nurse cells are shown in orange representing the overlap of phases (border cell cluster phase variable and nurse cell phase variables ). The small gray arrows show the gradient of cluster phase and large blue arrows show the tangential vectors corresponding to the vectors orthogonal to the gradient (. Chemoattractant molecules (magenta dots) indicate that the presumed concentration at the front of cluster (posterior side) is more than at the back of the cluster (anterior side), which amplifies the movement of cluster from the anterior to the posterior.
