The expression of p-Elk1-IR cells in spinal cord dorsal horn of rats in the control group and at 6, 25 and 49 h after subcutaneous injection of CFA into the plantar hind paw region. A-D. Immunohistochemical analysis shows p-Elk1-IR cells in the L4-6 ipsilateral spinal cord dorsal horn of control rats (A), model rats at 6 h (B), 25 h (C) and 49 h (D). E. Quantification of p-Elk1-IR cells in L4-6 ipsilateral spinal cord dorsal horn, respectively. Results are mean ± SEM; n = 6. *P < 0.05, **P < 0.01 versus control group at the corresponding time point. The scale bar is 100 μm.
