Abstract:
On the basis of an outline on Governor Vessel acupoints electroacupuncture ,endogenous neurotrophic factor expres?sion,grafted adult stem cell-derived neurons integrating to spinal host neuron circuit for repairing spinal cord injury ,it is summa?rized that mechanism of a combination of Governor Vessel acupoints electroacupuncture and grafted adult stem cells improving the tis?sue microenvironment of spinal cord injury to reestablish neuron conduction pathway. Governor Vessel acupoints electroacupuncture stimulate meningeal branch of spinal nerve in rat spinal cord transected or demyelinated. The stimulation message is input into spinal cord through afferent nerve,which activates spinal cord cells synthesizing and secreting neurotrophin-3(NT-3). The NT-3 can pro?mote the survival,differentiation and migration of exogenous neural stem cells(NSC)and bone marrow mesenchymal stem cells (MSC)expressing tyrosine kinase receptor C(TrkC)at the injury/graft site or demyelination/graft site in the spinal cord transected or demyelinated. The combined therapeutic strategy may replace and protect host neurons injured ,perfect tissue microenvironment in?jured,promote nerve fiber regenerating,and improve motor evoked potential of cerebral cortex and motor function of paralysis limbs.
