(E) The relative spindle angle between the polarity axis perpendicular to the apical phalloidin-stained F-actin surface and the MS was determined in metaphase Caco-2 cysts cells transfected with control, ALIX and/or γ-tubulin siRNA (29, 29, 18 and 32 metaphase cells, respectively, were analyzed from three separate experiments). Compared to control cells, depletion of either ALIX or both ALIX and γ-tubulin, induced a significantly increased randomization of the relative spindle angles (**p<0.01 and ***p<0.001, ANOVA). Caco-2 cells depleted of ALIX+γ-tubulin showed a greater variation in the spindle angles compared to depletion of ALIX or γ-tubulin (*p<0.05, ANOVA). ALIX-depleted cells showed greater spindle angle-variation than γ-tubulin-depleted cells (*p<0.05, ANOVA)
