Effect of platelet rich plasma (PRP) on axonal regeneration at 5 weeks after spinal cord injury (SCI). A–C: Representative photomicrographs of the thoracic transverse sections (T10) showing biotinylated dextran amine-labeled corticospinal tract (CST) fibers visualized by diaminobenzidine (DAB) staining technique (brown spots) in the control (A), rats treated with PRP 1 week after SCI (B) and rats treated with PRP 24 h after SCI (C). Arrows indicate biotinylated dextran amine (BDA) labeled CST fibers (magnification ×400). D: Quantitative data showing the numbers of BDA-labeled axons per section (n = 12/group). Data were shown as mean ± SEM. ***P < 0.001, as compared with control group.
