Repair effect of nerve fiber and axonal regeneration of SCI model rats 28 days after treatments: (A) Nissl staining of longitudinal slide position around damage site after treatments (×200), (B) immunofluorescence staining of neuron (×400), (C) immunofluorescence staining of neurofilament 200 (NF-200) in longitudinal slide position around the damage site (×200; dashed lines indicate the injured border), and (D) immunofluorescence staining of BDA protein after different treatments (×200; white arrows indicate the neonatal axon).
Abbreviations: SCI, spinal cord injury; BDA, biotinylated dextran amine; FGF2, fibroblast growth factor-2; dscECM, decellular spinal cord extracellular matrix; HP, heparin-poloxamer.
