Spindle Angle Measurements
Abstract
Spindle angles measures derive from the measures of spindle poles positions that were taken from fixed and immunostained adherent cells. To determine spindle angles (α), z-stack images of metaphasic cells immunostained with anti γ-tubulin (spindle poles) and anti β-tubulin antibodies (mitotic spindle) were acquired. A very simple ImageJ software macro was developed to measure the spindle angle using spindle pole coordinates (see Figure 1).
