This study investigates the mechanical oscillations that occur during 2D collective cell migration. It focuses on the propagation of waves, monolayer free expansion, standing waves, and swirling motion of a confluent monolayer. It also examines the viscoelasticity that can lead to oscillatory instabilities, known as elastic turbulence. The Weissenberg number is used to measure the strength of the elasticity. This research provides insight into the dynamics of collective cell migration, which is important for understanding tissue formation and morphogenesis.
