Brief description Multiple sclerosis is a disease of the central nervous system in which myelin (an insulative coating around the axons of neurons) and oligodendrocytes (the cells that produce myelin) are attacked and damaged by an unknown process. This damage is referred to as demyelination and results in a blocking or weakening of nerve signal conduction. Some of the symptoms of multiple sclerosis are weakness, tingling or numbness of limbs, and double vision or visual loss. One strategy to repair the demyelination is to transplant cells into the damaged brain that can replace the damaged oligodendrocytes and remyelinate. Studies have shown that oligodendrocyte progenitor cells and neural stem cells transplanted into the brain can mature into oligodendrocytes and myelinate axons. However these cells are very difficult to obtain, the best source is foetal terminations but the use of such tissue raises ethical and practical problems. Recently cells found in adult bone marrow, called marrow stromal cells, have been shown to differentiate into neural cells when transplanted into the brain. This raises the possibility that sufferers of multiple sclerosis may be able to have marrow stromal cells taken from their bone marrow and then transplanted into their brains to replace their damaged oligodendrocytes. Our study will investigate the differentiation of marrow stromal cells into oligodendrocytes and determine if marrow stromal cells transplanted into demyelinated mouse brain can replace damaged oligodendrocytes and remyelinate areas of damage.
