Unexpected Cell Repairs the Injured Spinal Cord, Karolinska Institute Study

Karolinska Institutet has revealed how scar tissue is formed after damage to the central nervous system. For more than a century, scientists thought that glial cells were responsible for scar formation; now, however, a paper published in Science shows that spinal cord scar tissue largely derives from a completely unexpected type of cell called a pericyte, opening new opportunities for the treatment of damaged nerve tissue.
