Animation of Stem Cell Scarring and Spinal Cord Injury (VIDEO)
Caption
The animation shows a simplified view of lesion development after spinal cord injuries in mice, with and without the resident neural stem cell injury response. The neural stem cells (green) respond to injury by producing progeny that migrate to the lesion site where they contribute to the forming glial scar. Without the neural stem cell response, the injury gradually expands and more nerve fibers are cut off, suggesting that the neural stem cell-derived scar tissue prevents the lesion from expanding. The findings are published in Science, November 1, 2013 by Professor Jonas Frisén and colleagues at Karolinska Institutet in Sweden.
