Survival of motoneurons in the spinal cord ventral horn (VH) at the 7th week after contusive SCI. A: Neutral Red staining shows VH neurons (arrows) from a CsA treated group in a section 8 mm rostral to the epicenter. B~E: Representative pictures show VH neurons (oval-shaped dotted line) at 3 mm rostral to the injury epicenter in the vehicle (B), CsA (C), GFP-OPC transplantation with vehicle (D) or with CsA (E) groups. F: Comparison of VH neurons among different groups at various distances from the injury epicenter (0) as well as at 1, 2, 3, 4 mm rostral (+) and caudal (-) to it. Data are given as means ± SD, n = 6, ** p < 0.01 (ANOVA). Scale bar in A: 20 μm, in B and C: 200 μm.
