High-resolution measurements of the coherent flows from collectives of eukaryotic and prokaryotic cells

Caption

a,b, Representative velocity and vorticity fields observed in monolayers of eukaryotic MDCK cells (a) and prokaryotic WT P. aeruginosa cells (b). The colour map shows the local vorticity and the zero-vorticity contours are marked with black lines. The vorticity is normalized by its maximum value. The insets show a subset of cells within a single field of view, which have been overlaid with green arrows showing the local velocity. Here we have quantified movement using single-cell tracking (PIV), but we have also verified our results using PTV.
