Stem Cell Treatments

There is a great deal of scientific and media interest in stem cells as a possible treatment for MS. Some scientific reports do reveal encouraging clinical findings, but a lot of work still needs to be done to prove their effectiveness and safety for people with MS.

MS Australia does not oppose stem cell treatment. Instead we want people to know all the facts, to fully understand the potential risks and side effects, as well as the potential benefits, and to most importantly discuss this with their neurologist to ultimately decide whether they are a suitable candidate for such treatments, the majority of which are still considered experimental. 

What are stem cells?

Stem cells are cells which are able to differentiate into other types of cells and are capable of ‘self-renewal’ or multiplying to produce greater numbers. The aim of some stem cell research is to use or manipulate those stem cells to help regenerate lost tissue.

What is stem-cell treatment?

Stem cell therapy is any treatment that uses or targets stem cells. This is usually to help replace or repair damaged cells or tissues, but can also be used to prevent damage from happening in the first place. Stem cell therapy might either involve transplanting stem cells or giving drugs that target stem cells already in the body.

The majority of stem cell research in MS is still in the relatively early stages and there is not as yet a proven stem cell treatment that has been shown to repair damaged myelin or nerves in MS. Despite this there are clinics within Australia and around the world that offer stem cell treatments for MS and other conditions (for example using stem cells derived from fat tissue retrieved by liposuction). It is important to note that the safety and efficacy of these treatments is currently unknown and unproven. The National Health and Medical Research Council has produced a useful resource for people who might be considering a stem cell treatment outside of an approved clinical trial – you can download the resource here


Autologous haematopoietic stem cell transplant (AHSCT) treatment

The only stem cell-based treatment that is currently in use for MS, and supported by clinical research findings, is an immune-suppressing chemotherapy treatment, called autologous haematopoietic stem cell transplant (AHSCT). This chemotherapy treatment destroys the patients’ immune system and then uses blood and immune stem cells from the bone marrow (haematopoeitic stem cells) to help restore, or reset, the immune system following the chemotherapy. This is an intensive and relatively high risk form of treatment and is generally only considered by Australian hospitals as being suitable for people with aggressive forms of MS who have not responded to other available MS therapies.

Our colleagues at MS Research Australia have provided a comprehensive resource on their website with further details on AHSCT treatment, what research has told us about the safety and efficacy of this treatment for MS and what is happening in Australia with AHSCT.

Mesenchymal stem cells

Mesenchymal stem cell therapy is a different treatment to AHSCT. As explained above, AHSCT is designed to restore the immune system through the re-infusion of the patient’s own blood and immune stem cells following chemotherapy treatment, which completely or substantially depletes the immune system.

Mesenchymal stem cell (MSC) therapy does not involve chemotherapy and uses a different type of stem cell which can be isolated from different tissues, including bone marrow and fat.

In laboratory studies, mesenchymal stem cells have shown the potential to develop into a range of other cell types including muscle, connective tissue and nerve cells; they also secrete growth and other factors that may influence the immune system. The evidence to date from animal studies and very early stage human trials suggests that the therapeutic potential of MSCs may come from the chemicals they secrete that appear to calm the immune system and contribute to an environment that is more supportive for self-repair of the central nervous system.

Some media reports have highlighted research underway regarding clinical trials of an exploratory stem cell trial in Israel involving the use of mesenchymal stem cells.
