Spinal cord regeneration might actually be helped by glial scar tissue

Few neuroscientists question the idea that scar tissue formed by glial cells after brain or spinal cord injury impedes regrowth of damaged nerve cells. But now, working in mouse models, a team of scientists has found that glial scar tissue formed after spinal cord damage may actually favor nerve cell regeneration. This study may ultimately guide development of new approaches to repair catastrophic spinal cord injury.
