Transplantation of platelet-derived growth factor (PDGF)-AA-overexpressing oligodendrocyte progenitor cells (OPCs) improves locomotor recovery after spinal cord injury (SCI). (A) Rats that received PDGF-AA-overexpressing OPC transplantation showed greater improvement in locomotor Basso, Bresnahan and Beattie (BBB) score at 3 weeks as compared to controls (n = 15). (B) The PDGF-AA-overexpressing OPC transplantation group had fewer footfall errors in the grid-walk analysis than control animals 6 weeks post-transplantation. Data represent mean ± SD (n = 15). *P < 0.05, **P < 0.01.
