Using two different lesion models, the spinal root avulsion and the distal nerve axotomy, the present study investigated effects of known neurotrophic factors on motoneuron survival in newborn rats. Results of the present study show that 100% of motoneurons in the lesioned spinal segment die at 1 week following root avulsion, and more than 80% of them die at 2 weeks following distal nerve axotomy. Local application of GDNF can rescue 92% of motoneurons up to 1 week from degeneration due to root avulsion and almost 100% of them up to 2 weeks from degeneration due to distal nerve axotomy. Local application of BDNF fails to prevent any motoneuron death in newborn rats following root avulsion, but it can rescue about 50% of motoneurons up to 2 weeks from degeneration due to distal nerve axotomy. CNTF and IGF-1 fail to prevent any motoneuron death following either distal nerve axotomy or root avulsion. Thus, comparing all the neurotrophic factors tested in this study, GDNF is most effective in preventing death of motoneurons following axonal injury in newborn rats.
