The use of Stem Cells (SC) in brain injuries is due to the lack of effectiveness of the existing methods of therapy of such patients. The perineural method of SC implantation, in comparison with intravenous or endolumbar methods, opened the possibility of natural SC migration along cranial nerves (olfactory and trigeminal nerves) into the cranial c...
