Cells may experience physical confinement when migrating
through extracellular matrices. In confinement, processes typically
associated with 2D migration e.g. actin polymerization are inhibited.
Now, a chemotaxis-based microﬂuidic device containing microchannels of varying
cross-sectional areas reveals an alternative mechanism of migration in
confinement: water permeation and active and passive ion transport.
