Fig. 6. Re-establishment of spindle bipolarity relative to changes in half-spindle length in cut cells. (A) Polarization microscope images illustrating length change measurements (n=8) of the new (d₁) and original (d₂) half-spindles with respect to the furrow position (line). Time is given in minutes. (B) Bar chart showing that during furrow ingression, the length of the new half-spindle (d₁) has more than doubled, from 5.48±1.75 to 12.45±1.76 µm, whereas that of the original half-spindle remains relatively unchanged (d₂). Scale bars: 10 µm.
