Kazuya Suzuki, Takeshi Itabashi, Shin’ichi Ishiwata “Mechanical properties of spindle poles are symmetrically balanced”

【Significance】
The symmetry in mechanical properties is dynamically balanced in a pair of spindle poles.

Although spindle pole structure has been suggested to determine the mechanical properties of the overall spindle structure, quantitative analysis for the pole mechanics has not been performed. Here, we demonstrate that the mechanical properties including shape, stiffness and microtubule density of pairs of pole regions are symmetrically balanced in single spindles. We found that, when the one pole region was widened with two microneedles, the other pole region was spontaneously widened to form a barrel-like shape. These results suggest that the spindle symmetry in mechanical properties is dynamically maintained.
