Summary:
Damaged nerve cells in a finger will regrow, but those in the spinal cord do not. Why the difference? Scientists at the Max Planck Institute for Neurobiology working with an international team of researchers can now explain two important details. Nerve cells in the spinal cord still have the ability to grow even many weeks after an injury. However, the regeneration is prevented by scar tissue created after the injury occurs. Now that they have this knowledge, scientists can search for ways to reduce the scar tissue and activate the relevant growth mechanisms. ( Current Biology, June 2009)
