Scientists grow neurons using nanostructures
EVANSTON, Ill. --- Scientists at Northwestern University have designed synthetic molecules that promote neuron growth, a promising development that could lead to the reversal of paralysis due to spinal cord injury.
"We have created new materials that because of their chemical structure interact with cells of the central nervous system in ways that may help prevent the formation of the scar that is often linked to paralysis after spinal cord injury," said Samuel I. Stupp, Board of Trustees Professor of Materials Science and Engineering, Chemistry and Medicine.

A liquid that forms a gel-like mass of nanofibres on contact with water could provide the most promising vehicle yet for the regeneration of damaged spinal cords.
Many groups working in regenerative medicine are trying to develop artificial scaffolds that store or attract cells and then control their growth and final identity.
