Expression of neural cell adhesion molecule at neuromuscular junction after lumber nerve root injury
Abstract：AIM: To investigate the expression of neural cell adhesion molecule(N-CAM) at the neuromuscular junction after lumber nerve root injury.METHODS: The distribution changes of N-CAM at flatfish muscle neuro-muscular junction of rat in its embryon phase, 14-day after birth, adulthood and 10, 20 and 30 days after its L5 lumber nerve root injury were observed by immunohistochemistry and confocal laser scanning microscopy technologies.RESULTS: N-CAM at muscle canal surface and neuromuscular junction were dyed intensively in strength at the embryon phase in rat, and the strength decreased during its growth and almost disappeared in its adulthood. However,N-CAM's repetition appeared after the innervation loss in muscle.Expression of N-CAM is regulated by the condition of nerve control.
