Effect of intraspinal injection of human adipose-derived stem cells (hADSCs) and low-level laser therapy (laser) alone and combination therapy on mechanical allodynia (a), cold allodynia (b), mechanical hyperalgesia (c), heat hyperalgesia (d) and (e) motor function recovery after spinal cord injury (SCI). Data are expressed as mean ± SEM (n = 8 in each group). *p < 0.05, **p < 0.01, ***p < 0.001 versus SCI groups. ^#p < 0.05, ^##p < 0.01, ^###p < 0.001 versus control group. ^$p < 0.05, vs laser group
