Fig. 4. Histogram representing the optical density of GFAP in DRG, spinal cord from sham (n = 4), PDRN-treated SNL mice (n = 6), and vehicle-treated SNL mice (n = 4). The expression of GFAP in the PDRN-treated group (DRG, 64.19 ± 46.21 optical density; spinal cord, 47.35 ± 22.12 optical density) was significantly decreased compared to the vehicle treated group (DRG, 169.13 ± 71.01 optical density; spinal cord, 118.01 ± 50.82 optical density).
GFAP = glial fibrillary acidic protein, DRG = dorsal root ganglia, PDRN = polydeoxyribonucleotide, SNL = spinal nerve ligation.
