Expression of synaptophysin, TNF-α and NGF in dorsal root ganglion cell culture subjected to electrical stimulation a Representative of immunohistochemical staining of synaptophysin, TNF-α and NGF over the dorsal root ganglion cell culture subjected to different frequencies of electrical stimulations. b Representative of western blot analysis of synaptophysin, TNF-α and NGF over the dorsal root ganglion cell culture subjected to different frequency electrical stimulations. c Quantitative analysis of the western blot of synaptophysin, TNF-α and NGF in the dorsal root ganglion cell culture subjected to different frequencies of electrical stimulation. Sham: dorsal root ganglion cell culture without electrical stimulation; LF: low-frequency electrical stimulation; HF: high-frequency electrical stimulation; *p < 0.01 indicated a significant difference compared to the sham group; #p < 0.05 indicated a significant difference compared to HF; bar length = 100 μm; n = 3
