In conclusion, Schwann cells from wallerian degenerating facial nerves of rats might bear with similar biological characteristics and functional phenotype to those from sciatic nerves in vitro, and they might be able to produce soluble NTFs for trophic support on facial motoneuron cultures. The establishment of methods for obtaining high-purity facial motoneuron cultures of rats with partially labeled fluorescence should be of significance in contribution to further investigation on facial motoneuron's response to NTFs and other affecting factors.
