Therapy of traumatic injuries of the spinal cord by magnetic nanoparticles: experimental aspects of promising technology

Abstract

In this analytical review an attempt to sum up the available data in magnetite nanoparticle-marked stem cells utilization is made. Now this question remains on the experimental study level. Available data is diversified and needs an integral look to be taken. It is found that magnetite nanoparticles are non-toxic for the cells and do not interrupt physiological metabolic pathways. They can also be captured by cell using different transporters. Cells containing the magnetite nanoparticles can migrate along the magnetic flux lines. Animals with traumatic spinal cord lesions that got the nanoparticles-containing cell therapy showed the neurological status improvement. There is very little data in usage of this method in clinical practice; the solution of this problem requires more clinical trials.
