Research published this week depict a promising head start to using base cell therapy for multiple sclerosis . In a small Phase I trial , patient who had stem cell directly throw in into their brain appeared to tolerate it well and experienced no serious inauspicious effect . The treatment may have also stop or slow up the progress of their symptoms , the scientist say , but larger studies will be needed to confirm its strength .
Multiple sclerosisis an autoimmune condition because of the unwavering worsening of our aflutter organisation ’s myelin sheath — the protective coating around heart electric cell . People with MS experience various neurological symptoms , including numbness , heftiness weakness , pain , and difficulty walk . There are different forms of MS , classified by the length and procession of their symptom . Most citizenry with MS have symptom that pass off and reoccur at first , for example . But finally , many grow secondary progressive MS , which is when symptom block disappearing and only get worse over meter .
research laboratory and animal studies have suggested that stem prison cell — so - call building blocks that have the ability to become many different types of cell — could accommodate the key to stopping or even turn back the progression of MS . And we ’re now starting to see the first human trial run test out the voltage of prow cubicle therapy .

This new research , publishedMonday in Cell Stem Cell , is a collaboration between scientists from the University of Colorado , the University of Cambridge in the UK , and the University of Milano - Bicocca in Italy . It involve 15 patients from Italy diagnosed with secondary MS . The patients were give neuronal stem cells originally derived from a single bestower ( a fetus that died of abortion ) via an injection directly into the brain . Then they were observe for a year ’s time .
Phase I trials primarily focus on a discourse ’s safety and tolerability . And the therapy did appear to pass this test , with no serious untoward effect or deaths reported during the trial . Other adverse event were mild , short - lasting , and possibly related to the other medications people were taking for their MS . Importantly , patients also experienced no progression of their symptom . And in a subset of patients , the researchers found grounds that a outstanding dose of root word prison cell was tied to a boring reduction in brain bulk , possibly a mansion that the treatment can slenderize MS - related inflammation .
These findings are still very former , and many treatment that seem to form well in Phase I research go on to fail when tested out in more extensive test . But for now , the researcher are cautiously optimistic about the future of stem cell therapy for MS . The squad is already plan to conduct larger study , while other scientists are exercise on theirown run .
“ We recognise that our study has limitations — it was only a small study and there may have been confounding effects from the immunosuppressant drugs , for instance — but the fact that our treatment was safe and that its effects lasted over the 12 calendar month of the trial means that we can proceed to the next stage of clinical trials , ” said study generator and Cambridge researcher Stefano Pluchino in astatementfrom the university .
