Single-unit recording of wide dynamic range (WDR) neurons in the dorsal horn of the L4 and L5 spinal cord 8 weeks after transplantation of human bone marrow-derived mesenchymal stem cells (BM-MSCs) and umbilical cord-derived mesenchymal stem cells (UC-MSCs). Evoked potential of the WDR neurons to stimulations received from Aβ neurons (a), Aδ (b), and C fibers (c), post-discharge response (d), and wind up (e) are presented as means ± SEM (n = 6 in each group). ^# p < 0.001, versus SCI group; *p < 0.01, **p < 0.001, versus sham animals; ^$ p < 0.01, versus BM-MSC treated animals.
