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

Figure 8 We observed immunohistochemical transforming growth factor-β 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-transforming growth factor-beta (TGF-β) 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 TGF-β indicated by brown.
