Microtubules associated with nuclear pore complexes and coated pits in the CNS.
Using a new albumin prefixation technique, microtubules have been observed in close association with the nuclear pores of neurons and glia. Thus, microtubules may be involved in such phenomena as anchoring, migration or rotation of the nucleus or in chemical messenger transport between nucleus and cytoplasm. Microtubules are also seen running close to the coated pits of dendrites. The implications are discussed.
