BMSC transplantation restored the volume of spared spinal cord and improved the Hind limb motor function of tree shrews after Hemi-sectioned spinal cord injury (hSCI). (A) Control group showed no positive staining. (B) BMSCs with Hoechst blue staining were widely diffused in the injured tissues at 28 days after injury. (C) Structure of the spinal cord in the sham tree shrews. (D) Structure of the spinal cord in the hSCI tree shrews. (E) Comparatively, BMSCs transplantation resulted in a significant increase on the volume of spared spinal cord. The pictures were taken at 1 cm below the lesion. Bar = 100 μm. (F) The bar chart for quantitative analysis of the volume of spared spinal cord among the sham, hSCI, and BMSC groups using Image-Pro plus 6.0 software. *p < 0.05 compared with the control. Data are presented as the mean ± SD (n = 5, one-way ANOVA). (G) Basso, Beattie, and Bresnehan (BBB) scores among the sham, control and BMSC groups at day 1–28 after injury. *p < 0.05 compared with the control. Data are presented as the mean ± SD (n = 10, one-way ANOVA). Arrowheads indicate the BMSC transplantation time. Control is the hSCI control group. BMSC group is hSCI + BMSCs group.
