Figure 1. — Changes in VEGF-A expression in the rat medullary dorsal horn after inferior alveolar nerve injury produced by a malpositioned dental implant. (a) Inferior alveolar nerve injury increased the number of VEGF-A immunoreactive cells in the ipsilateral medullary dorsal horn compared with the sham group. Scale bar, 100 μm. (b and c) Western blot analysis showing significantly increased VEGF-A expression on POD 1, 3, and 5 after inferior alveolar nerve injury compared with the sham group. GAPDH was used as a loading control. There were eight animals in each group. *P < .05, sham vs. nerve injury group. VEGF-A: vascular endothelial growth factor-A; GAPDH: glyceraldehyde 3-phosphate dehydrogenase; POD: postoperative day.
