Fig. 4. MDCK cells within a confluent monolayer migrate in a spatially heterogeneous manner (A, B).

Fig. 4

The average area of contiguous regions of the fastest velocity vectors defines ξh, the area of dynamic heterogeneities (B, white regions). As cell density rises, ξh grows from an area of about 10 cell bodies to 30 cell bodies (C, inset: ξh in μm2). The average migration speed of cells within the entire field of view, ν, decreases with increasing cell density (D). (Scale bar, 100μm.). Reprinted with permission from 17
