Table 2. Comparison of cell motility and cell pattern.

| Speed (µm/h) | 623±36 | 511±29 | 105±7 | 35±1.8 | 21±2.4 | 63±15.4 | 46±2.9 | 32±1.4 |
| Diff. coeff. (µm2/min) | 116±1.5 | 158±1.7 | 134±0.7 | 1.7±0.01 | 1.6±0.01 | 0.6±0.01 | 1.29±0.01 | 3.6±0.01 |

Cell motility data were calculated from tracked trajectories of cell populations in 3 typical densities for each cell type. Note the increase in persistence length for clustered cells in all cell types.
