Epithelial sheet


This project focuses on understanding and explaining how cells in a 1D sheet interact with neighbouring cells and how they grow, divide and migrate.

Zebrafish primordium formation


The zebrafish posterior lateral line primordium formation is often used as a model for collective cell migration and cell polarity.
A cohesive cluster of over 100 cells, which originates posterior to the ear, migrates along the embryonic trunk. The cluster polarizes along a gradient of SDF-1 which is expressed in a narrow line along the horizontal myoseptum. During migration cells in the trailing two thirds of the primordium organize into two or three garlic bulb-shaped rosettes. At regular intervals a cluster of 20-30 cells gets deposited from the migrating cluster.
