Before revision:  Results: After exhibiting such a positional switch in C. elegans, we mapped the microtubule ends at the cortex and observed a correlation between the proximity of the centrosomes and the density of microtubule contacts.
After revision:  Results: After exhibiting such a positional switch in C. elegans, which we ascribed to microtubule dynamics at the cortex and observed a correlation between the proximity of the centrosomes and the density of microtubule contacts.
