Effect of hUCBSC-MO treatment on sensory function after SCI. Intraperitoneal injection of MO (150 mg/kg) was started 1 day after injury and continued once a day for 14 days after injury. Intraspinal grafting of hUCBSCs was started 24 hr after injury. Data are represented as mean of latency time ± SEM, (n = 5–7) and analyzed by two-way ANOVA followed by post hoc Bonferroni’s multiple comparison test. ***p < .001 significant difference between SCI versus intact. ΩΩ, and ΩΩΩ show significant difference between SCI-MO and SCI. ΦΦ, and ΦΦΦ show significant difference between SCI-hUCBSC and SCI. #, ##, and ### show significant difference between SCI-MO-hUCBSC and SCI (p < .05, p < .01, and p < .001, respectively). Note. hUCBSCs = human umbilical cord blood stem cells; MO = Melissa officinalis; ANOVA = analysis of variance; SCI = spinal cord injury.
