Correlation between the relative abundance of different centriolar, centrosomal, and spindle pole proteins at the two poles of the mitotic spindle and the SAI, in metaphase RPE1 cells with different centriole numbers.
Pearson’s correlation coefficient between the relative protein distribution and the SAI.
P value of the correlation. ns = not significant; P ≤ 0.05 = *; P ≤ 0.01 = **; P ≤ 0.001 = ***; P ≤ 0.0001 = ****.
Number of cells.
Slope of the linear regression.
The active form of Aurora-A (anti phospho-threonine 288) was quantified.
