Abstract

Successful axon regeneration depends on the expression of regeneration-associated genes by axotomized neurons. Here, we demonstrate, for the first time to our knowledge, the expression of regeneration-associated genes by axotomized human CNS neurons. In situ hybridization and immunohistochemistry showed a transient induction of GAP-43 and c-jun in Clarke's nucleus neurons caudal to traumatic human spinal cord injury. These results support experimental data that nonregenerating central nervous system neurons can temporarily upregulate regeneration-associated genes, reflecting a transient regenerative capacity that fails over time.
