Figure 7.
Morphological observation of BMSCs in different groups. Images of the spinal cord in the (A) BMSC-Sna + NRG group, (B) BMSC-NC + NRG group, (C) BMSC + NRG group, (D) BMSC + Sna group, (E) BMSC-NC group and (F) BMSC group under a fluorescent microscope (magnification, ×40). (G) Distribution area of BMCSs. Data are presented as the mean ± standard deviation and P<0.05 was considered statistically significant. *P<0.05 BMSC-Sna + NRG group, vs. all other groups; #P<0.05 BMSC-Sna group, vs. BMSC-NC and BMSC groups. BMSC, bone marrow mesenchymal stem cells; Sna, Snail overexpression plasmid; NRG, neuregulin-1; NC, negative control.
