In the central nervous system, the glial scar is the main inhibitor of axon regeneration and functional recovery.

However, the optimal treatment time window and dose of X-irradiation for spinal cord injury is still unknown. Prof. Shiqing Feng and colleagues from Tianjin Medical University have verified that X-irradiation at a dose of 8 Gy can inhibit glial scar formation at the injury site and alleviate the inflammatory reaction; day 7 post injury may be the optimal time window for topical X-irradiation. These findings were published in the Neural Regeneration Research (Vol. 8, No. 17, 2013).
