Effect of hUCBSC-MO on electromyographic activity after SCI. Intraperitoneal injection of MO (150 mg/kg) was started a 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 recruitment index ± SEM, (n = 5–7) and analyzed by two-way ANOVA followed by post-hoc Bonferroni’s multiple comparison test. ***p < .001 shows significant difference between SCI versus intact. ##p < .01 and ###p < .001 versus spinal cord injury. Note. hUCBSCs = human umbilical cord blood stem cells; MO = Melissa officinalis; SCI = spinal cord injury; SEM = standard error of the mean; ANOVA = analysis of variance.
