Neuroscientists have long believed that scar tissue formed by glial cells — the cells that surround neurons in the central nervous system — impedes damaged nerve cells from regrowing after a spinal cord injury. However UCLA scientists have now found that the glial scar tissue might actually favor nerve cell regeneration. The research, published in Nature, could ultimately lead to new approaches to repair catastrophic spinal cord injury.
