Figure 5. NF200 (A), GAP-43 (B), and GFAP (C) positive cells (brown) were observed in spinal cord tissues of spinal cord injury (SCI) rats by immunohistochemistry at 3 days, 1, 2, 4, and 8 weeks post-injection (×500, bar=100 μm). Data are reported as means±SD. *P<0.05 vs SCI group; &P<0.05 vs control exosomes; #P<0.05 vs miR NC; ˆP<0.05 vs miRNA-29b exosomes (ANOVA).
