Retrograde Labeling of Different Distribution Features of DRG P2X2 and P2X3 Receptors in a Neuropathic Pain Rat Model

Figure 1

Timeline diagram of the experiment. Twelve rats were randomized into two groups and received CCI or sham surgery procedures on day 0. The pain behavioral tests were performed from day 3 to day 15. FG retrograde trace labeling was performed at day 15. Three days later, the DRG was carefully harvested for further experiments.
