LLLT increases neuronal survival. (A–C) Representative double-immunostaining images of neurons and astrocytes at 3, 7, and 14 dpi. The epicentre of the section is outlined in accordance with GFAP expression. Right images in each panel are enlarged images of the boxed area rostral to the epicentre. (D) Quantitative analysis of neurons in regions 500 μm rostral (R1) and 500 μm caudal (C1) to the epicentre. Neuronal cell number was averaged and presented as cell number per mm2 cord section. NeuN, neuronal nuclei. GFAP, glial fibrillary acidic protein. In the left part of panel A, B, and C, bar = 500 μm. In the enlarged images, bar = 200 μm. (R1 or C1: 5 measurements per section and 2 sections per rat with 3 rats per group; *P < 0.05; **p < 0.01, compared with control).
