| Outline of Final Research Achievements |
In the transectioned zebrafish spinal cord model, upper motor neurons in the brain can survive and regrow their axon after spinal cord injury. The regenerative axons from upper motor neurons in the brain were accompanied with upregulation of IGF-1 expression in their soma. While lower appeared to be neurons were newly synthesized from ependymal cells nearly located near in the central canal of the spinal cord. Sensory neuron in the dorsal root ganglion can survive but not regrow their axons after spinal cord injury.
