Mean BBB score for hind limb motor recovery. All the transplanted groups showed improved BBB scores, except the SCI group, as shown in (A, B). Within-group comparisons before and after transplantation showed significant functional recovery after transplantation (p<0.05) (C). A comparison among the groups showed that 5, 10, and >10×10⁵ cell groups demonstrated significant improvements in motor function (p<0.05) compared with the SCI group. While all the transplanted groups showed functional recovery, only the 2 and 5×10⁵ cell groups showed significant differences (D). BBB, Basso, Beattie, Bresnahan scale; SCI, spinal cord injury; OEC, olfactory ensheathing cell.
