Stem cells hold promise for MS

There is exciting and innovative research and progress occurring related to the potential of many types of stem cells for slowing MS disease activity and for repairing damage to the nervous system. In light of the urgent need for more effective treatments for MS, particularly for those with more progressive forms of the disease, we believe that the potential of all types of cell therapies must be explored.

Stem cell therapy is any treatment that uses or targets stem cells, which are the types of cells that differntiate into many different specialized cells in our bodies. Stem cells are found in both embryos and adults.

Many types of stem cells are being explored for their potential benefits for treating multiple sclerosis. Only when the results of these and subsequent clinical trials are available will it be possible to determine what the optimal cells, delivery methods, safety and actual effectiveness of these current experimental therapies might be for people with MS.

Although cell based therapy has generated a great deal of interest and holds promise, the field is in its infancy and much more research is needed before cell based therapies become a MS treatment option. 

Different Types of Stem Cells

  • HSCs (haematopoietic stem cells) – adult stem cells that are found in bone marrow and blood. HSCs are capable of producing all of the cells that make up the blood and the immune system.
  • MSCs (mesenchymal stem cells) – adult stem cells found in several places in the body, including the bone marrow, skin and fat tissue. They produce cells which help other stem cells function properly.
  • NSCs (neural stem cells) – specialized stem cells responsible for repairing nerve-insulating myelin in the brain. These can be derived from other types of stem cells such as mesenchymal cells.
  • hESCs (human embryonic stem cells) – stem cells derived from donated embryos. They can naturally produce every type of cell in the body. One concern about their potential therapeutic use is that they have been found to cause tumors.
  • iPSCs (induced pluripotent stem cells) are engineered from adult cells to produce many types of cells. One concern about their potential therapeutic use is that they have been found to cause tumors.

Bone Marrow Stem Cell Transplant – HSCT

HSCT (Hematopoietic Stem Cell Transplantation) attempts to “reboot” the immune system, which is responsible for damaging the brain and spinal cord in MS.
