Stem cells are a powerful tool to help us understand what happens in MS.
Reprogramming your cells
Imagine being able to take a human skin cell and change it into a nerve cell, or a myelin-making cell, or an immune cell - just by adding a few chemicals.
It sounds like something out of a science fiction novel, but thanks to the work of Nobel Prize winners Sir John Gurdon and Shinya Yamanaka, it’s now a reality.
Researchers can take skin samples from a person and, in the lab, push these adult cells back into being stem cells. These ‘induced’ stem cells have the potential to become any cell in the body. Because of this, they are known as ‘induced pluripotent stem cells’, or iPS cells.
A new tool to study MS
iPS cell technology has opened up a whole new avenue of research, which our scientists at the MS Society Edinburgh Centre for MS Research are taking full advantage of.
Led by Professors Charles ffrench-Constant and Siddharthan Chandran, they’re using iPS cells to grow unlimited numbers of human-derived nerve cells and myelin-making oligodendrocytes in a dish.
Finding new treatments for MS
By using skin samples taken from people with MS, the researchers can grow nerve cells and oligodendrocytes that ’model’ the condition. Add in some immune cells and you have an insightful tool to study human MS in a laboratory dish.
Right now, the team in Edinburgh are using these cells to screen potential drugs and to learn more about what happens in progressive MS.
