Cellular proliferation in injured mouse spinal cords following BMMSC-IGF transplantation. Spinal cord segments from a uninjured mouse and SCI mice treated with b saline, c BMMSCs and d, e BMMSC-IGF1, observed by confocal microscopy, 2 days following spinal cord injury and cell transplantation, immunostained for Ki-67. Scale bars = 200 μm (ad); scale bar = 50 μm (e). Central canal (highlighted/insert, ad). f Quantitative percentage of Ki-67+ in the spinal cord 5 days post-injury. Values represent mean ± SEM. *P < 0.05; **P < 0.01; ***P < 0.001
