MSCs and EA treatment promoted axonal regeneration at the site of injury on day 14 after SCI. (A–E) Representative images of NF (white arrows)/GFAP immunostaining in the control (A), NA-EA (B), EA (C), MSCs (D), and MSCs+EA (E) groups. In the panels A–E, the scale=200 μm in the low magnification image; the scale=20 μm in the high magnification image. (F, G) Western blot analysis of NF protein expression in the 5 groups. Data are expressed as means ± standard deviation (n=5). GFAP, glial fibrillary acidic protein; SCI, spinal cord injury; MSC, mesenchymal stem cell; EA, electroacupuncture; NA-EA, nonacupoint EA; NF, neurofilament. Compared with the control group, **p < 0.01; compared with the NA-EA group, ##p < 0.01; compared with the EA group, &&p < 0.01; compared with the MSCs group, $$p < 0.01.
