Although the ontogeny was n’t cancerous , these findings shew just how significant safety monitoring is after theme cellphone treatments and how it should be defend for year . The team that removed the growth , led byBrianDlouhyfrom the University of Iowa , release thesurgery resultsinJournal of Neurosurgery : Spineearlier this month .
The olfactory stem cells were implant into her spine with the destination of experience them develop into nervous cells to help mend nerve damage , New Scientist explains . It did n’t work , and even though the unusual increase contain turn of off-white and tiny nerve branch , they did n’t associate with the spinal mettle .
" It is sobering,“says Harvard ’s George Daley , who was n’t involved with the study . " It speak directly to how rude our state of knowledge is about how cells mix and dissever and expand . "
This is the first account of a human spinal anaesthesia cord mass complicating spinal cord cellular phone transplant and neural prow cell therapy .
The unnamed cleaning woman was handle at the Hospital de Egas Moniz in Lisbon , where the squad welcome blessing for early - stage trial to explore the potential of nasal cell in treating palsy , New Scientist reports . In 2010 , the Lisbon teamreported resultsfrom a fender study where 20 patients with spinal corduroy injuries incur implant of “ olfactory mucosal autografts , ” modest pieces of the rhinal liner . All the patients last , and it seemed crusade in several of them had improved .
