Expression of α Tubulin Gene in Motoneurons of Spinal Cord During Nerve Regeneration

We have previously reported that the injury of sciatic nerve causes not only the change of axonal ultrastructures, but also the increase of β tubulin gene expression in the neural soma. And the microtubule, as a carrier of transported materials, of axonal architecture plays an important role. It has also been found that the content and transported velocity of tubulin in the regeneration nerve increase significantly owing to the requirements of axonal reconstruction. As the NOR-Ag staining technique is specific
