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 brain or spinal cord injury. So ...

Spinal cord injuries don't heal like cuts or broken bones. Why? Part of the reason is the formation of scar tissue that acts as both a chemical and physical barrier to nerve regeneration.
