The Morphofunctional Effect of the Transplantation of Bone Marrow Stromal Cells and Predegenerated Peripheral Nerve in Chronic Paraplegic Rat Model via Spinal Cord Transection

Figure 4

Photomicrography of the expression of Neuritin in spinal cord. (a) Control group. (b) Fibrin glue group (FG). (c) PPN group, rostral zone of the SC. (d) PPN + BMSCs group, rostral zone of the SC. (e) PPN group, caudal zone of the SC. (f) PPN + BMSCs group, caudal zone of the SC. A greater quantity of Neuritin positive fibers can be observed in panels (c) to (f) (white arrows, Alexa 488, green color), compared to panels (a) and (b). We can also observe that growth cones (red arrows) were only presented in the treated groups (panels (c) and (d)). All the tissue was contrasted with propidium iodide (nuclei red color). Calibration bar 20 μm.
