The fluorescent signal of FG and immunohistochemical signals of NeuN and FG in ischemic brain.

<p>A: Photographs showed that FG was injected into the ipsilateral SN (a, b and c) and its signals were observed in the pyramidal shaped neurons in the ipsilateral frontal and parietal cortex (f) and striatum (g) at 7 days after injection. Photographs c, f and g were magnifications of the square in photos b and e. Arrowhead in photograph b indicated where the needle was inserted toward the SN. B: Histochemical photographs displayed NeuN⁺ and FG⁺ single-labeling cells in the striatum (left) and cortex (right) of ischemic rat brain at 13 weeks after MCAO. C: Quantification showed that exercise post-stroke increased the number of NeuN⁺ and FG⁺ cells in ischemic rat brain. Data are shown as mean ± S.E.M. MCAO group (n = 8); MCAO+Ex group (n = 6). *<i>P</i><0.05 <i>vs</i> MCAO group. Scale bars are 1 mm in b and e; 100 µm in c, f and g; and 30 µm in B.
