An intervention may be on the horizon to treat those suffering from diseases such as Huntington’s, Parkinson’s and multiple sclerosis. According to researchers, neural stem cells (NSCs) have been “successfully” removed from the brains of rats using magnetic nanoparticles that, through a particular process, attach to NSCs. Once bonded to the nanoparticles and attracted to each other via a magnetic field, the NSCs are removed from the brain with a syringe, avoiding injury to the subject. Post op results showed no adverse effects on either the NSCs or the rats. Such harmless extraction is revolutionary but some researchers advise closer inspection for several reasons: the procedure has yet to be tested on humans, who carry fewer and less active NSCs; conceivable cultivation concerns; and confirmation is required that what was successfully extracted was the right stuff.
