Analysis of Microtubule Organization in a Neuron

Caption

A selected electron tomography slice shows microtubules, with the arrows indicating the direction of migration (top). The researchers used electron tomography to construct a 3-D model (bottom), and found that whereas most microtubules (green) are attached to the centrosome (blue), a small number are unattached. The unattached microtubules are able to undergo motor-driven sliding, which helps neurons migrate in a straight line.
