Figure 3.
Predicted half-width (A), (C) and half-length (B), (D) of the spindle for hinge (A), (B) and clamp (C), (D) connections at the centrosome as functions of the force per bundle. (E) Predicted aspect ratios (l/S) for the spindles with the clamped connection at the centrosome as functions of the force per bundle. Circles represent the computed values, curves—quadratic (linear for (E)) polynomial approximations. Distances are shown in units of 10 µm, forces—in units of 10 pN. It is not clear if negative (pulling) forces at the chrMT bundle tips are biologically realistic, but mathematically they lead to realistic shapes for the clamped connection.
