Boxplot representing concentrations of analyzed factors in plasma (pg/mL) measured on days zero, three, five, and seven after intrathecal administration of bone marrow-derived lineage-negative cells (n = 18). Significance of the changes between analyzed timepoints was assessed using Wilcoxon signed-rank test. Whiskers range from 10th to 90th percentile. Horizontal line inside the box indicates the median. Level of significance-** p < 0.01. CRP: C-reactive protein; BDNF: brain-derived neurotrophic factor; NGF: nerve growth factor beta; NT-3: neurotrophin-3.
