Stem cell research tudies have shown that there may be a chance of using this therapy to help MS sufferers.
Multiple sclerosis is, at present, an incurable degenerative neurological disease. It's autoimmune - where the body attacks itself - and results in destruction of myelin (the lining surrounding the nerves) within the central nervous system (the brain and the spinal cord).
It's one of those conditions I'm always hoping I won't see signs of in a patient.
Some MS patients will be lucky and the disease may not progress quickly but if the process of inflammation and scarring is not controlled then eventually the condition can cause permanent neurodegeneration.
In these trials, scientists destroyed the faulty immune system using chemotherapy. The stem cells originate from a patient's own blood and are used to help rebuild the immune system. These cells are at such an early stage that they've not developed the flaws that trigger MS.
The issue that the BBC highlights is that, '...the procedure involves no new drugs [therefore] there is little profit incentive for drug companies to get involved. So these advances to date have been achieved this without industry backing.
In addition, Dr Emma Gray, head of clinical trials at UK's MS Society, points out that: "Trials have found that while HSCT may be able to stabilise or improve disability in some people with MS it may not be effective for all types of the condition."
Dr Gray said people should be aware it was an "aggressive treatment that comes with significant risks", but called for more research into HSCT so there could be greater understanding of its safety and long term effectiveness. Because it may have a life-changing impact.
