The time courses of neurological function assessment. A Illustrating the inclined plane test for determining limb motor function on days 0, 3, 14 and 28 after acute ICH induction. B Statistical analysis by day 0, p > 0.5. C Statistical analysis by day 3, *versus other groups with different symbols (†, ‡), p < 0.0001. D Statistical analysis by day 14, *versus other groups with different symbols (†, ‡, §), p < 0.0001. E Statistical analysis by day 28, *versus other groups with different symbols (†, ‡, §), p < 0.0001. F Illustrating the corner test for determining limb motor function on days 0, 3, 14 and 28 after ICH procedure. G Statistical analysis by day 0, p > 0.5. H Statistical analysis by day 3, *versus other groups with different symbols (†, ‡), p < 0.0001. I Statistical analysis by day 14, *versus other groups with different symbols (†, ‡, §), p < 0.0001. J Statistical analysis by day 28, *versus other groups with different symbols (†, ‡, §), p < 0.0001. All statistical analyses were performed by one-way ANOVA, followed by Bonferroni multiple comparison post hoc test (n = 10 for each group). Symbols [(*, †, ‡, §) indicate significance (at 0.05 level). IA = intra-carotid arterial administration; IV intravenous (i.e., tail vein) administration; SC = sham control; ICH = intracranial hemorrhage; Ir-MNa-hUC-MSC = Ironic Magnetic Nanoparticles/human umbilical cord-derived mesenchymal stem cells
