The microtubule cytoskeleton of a stationary neuron. Purified cerebellar granule neurons were labeled with Ven--tubulin and cultured on a Matrigel-coated culture surface. Although stationary neurons had a perinuclear cage of microtubules the cage remains compact and does not change shape. Microtubule dynamics are evident in the growth cone at the end of the extending axon. Images from this sequence were used in Fig. 1c. Total elapsed time was 8 min.
