BBB locomotor rating scale. After the SCI, the BBB score in each injured group dropped significantly, and then a slow recovery was observed until W12. From W10, the BBB score in the SVF group became higher than in the NaCl groups. Significant difference in the BBB scores is indicated by a * (NaCl group vs. SHAM group), + (SVF group vs. SHAM group) and δ (SVF group vs. NaCl group). (1 symbol, p < 0.05, 2 symbols, p < 0.01 and 3 symbols, p < 0.001)
