This study shows that the stiffness of primordial germ cells is required for their arrest and extravasation in avian embryos, with actin polymerization regulating this stiffness.

The paper shows that the embryonic brain and scalp tissues mechanically interact, with the scalp recoiling to confine and fold the brain during development.

The paper identifies a preplate neuron stream that physically drives neocortical ventral expansion and somatotopic map formation through mechanical forces.
