Histological analysis using H&E staining. (A) Four weeks post-injury, in group A at the affected site of the damaged spinal cord exhibited a clear cavity formation. (B) In group B, astrocytes congregated at the edge of the affected site and formed scars at the junction of complete spinal cord and damaged spinal cord. The tissue cavity was smaller than that in group A but larger than that in group C. (C) In group C, astrocytes underwent a reactive hypertrophy, and congregated and formed scars at the edge of the affected site, resulting in the cavity disappearing. Arrows show Syringomyelia and scar healing. Scale bar, 100 μm.
