Histopathological changes.

<p>(A) Nissl bodies were stained with toluidine blue (nissl staining). Neurons, GFAP and NF200 in SCI rats was detected by immunohistochemical staining. The second antibody of NF200 is FITC luminescence antibody. Scale bar = 100μm (B) Numbers of nissl bodies was analyzed. (C) Analysis of numbers of neurons. (D) Analysis of the GFAP positive cells. (E) Optical density statistics of NF200. Data are presented as Mean ± SEM, n = 5. *P<0.05, **P < 0.01, ***P < 0.001, #P < 0.05, ##P < 0.01 and ###P < 0.001. (n = 5). *: other groups VS SCI group, #: bFGF-GMSs group VS bFGF group.
