Mechanism of spinal cord injury regeneration and the effect of human neural stem cells-secretome treatment in rat model

Figure 9 We observed immunohistochemical vascular endothelial growth factor average value of 10 field of views, every field of view have 625 µ² with 400 × magnification. A: Treatment group; B: Control group; C: Normal group. Microglia are small round cells, solid nuclei and give a positive reaction with anti-vascular endothelial growth factor (VEGF) indicated by brown color. While macrophage cells are large, vesicular nucleus, and sometimes elongated resembling fibroblasts (macrophages like fibroblast) and give a positive reaction with anti-VEGF indicated by brown.
