Figure 4.

Snapshots from the time evolution of the MT cytoskeleton configuration under the effect of cortical sliding mechanism with a low dynein density, ${\tilde{\rho }}_{\text{IS}}$ = 60 μm⁻². The cyan cylinder indicates the IS area. Blue and yellow lines are unattached and attached MTs, respectively. The black spheres in the IS are the positions of dyneins attached to MTs. (a and d) ${\overline{d}}_{\text{MIS}}$ = 9 μm. Originally, the attached MTs aim from the MTOC in every direction. (b and e) ${\overline{d}}_{\text{MIS}}$ = 4.5 μm. MTs attached to dynein aim predominantly in one direction. (c and f) ${\overline{d}}_{\text{MIS}}$ = 1.5 μm. Just a few MTs remain under the actions of cortical sliding, and they rarely touch the surface of the cell in the IS. To see this figure in color, go online.
