First stem cell clinical trial for treating brain’s “communication highway” to begin

Summary:

UCSF researchers are set to begin a Phase I clinical trial in collaboration with StemCells, Inc. to test the safety and preliminary effectiveness of using neural stem cells to treat children with a rare, fatal form of a brain disorder known as Pelizaeus-Merzbacher disease (PMD). Currently, there are no effective treatments for the fatal forms of the disease, which affects males that inherit a single defective gene.

The trial is the first neural stem cell trial in the United States designed to treat a disease resulting from a lack of “myelin,” a substance that insulates nerve cells’ communications fibers. Nerve cells communicate through axons that function much like electrical wires. Myelin is the insulating coat that surrounds the axons to prevent short circuits. Damage to the cells in the brain that make myelin, called “oligodendrocytes,” is the hallmark of multiple sclerosis and is involved in certain forms of cerebral palsy.
