Figure 3. Newborn neurons formed projections to the substantia nigra in ischemic rat brain.

A–D: Confocal microphotographs showed GFP⁺-NeuN⁺-FG⁺ triple-labeling cells (triple arrowheads) in the ipsilateral striatum (A and B) and parietal cortex (C and D) at 13 weeks after MCAO. NeuN⁺ single-labeling cells, GFP⁺-NeuN⁺ and NeuN⁺-FG⁺ double-labeling cells were indicated by single arrowhead, double arrows and double arrowheads, respectively. Scale bars are 20 µm.
