Table 1.

A compressed spindle expands asynchronously and reversibly. Expansion and contraction timescale (Δt), extent (Δ) and velocity (v), for spindle length (L; Lo, pre-compression value), spindle width (W), cell length (CL), and cell width (CW). Data was indiscriminately averaged over all experiments. Mean ± standard deviation
