Double immunofluorescence staining for BrdU, NeuN and GFAP. The majority of BrdU-incorporated cells expressed NeuN in the ipsilateral SVZ (A-C) and striatum (E-G) at 28 days after stroke while only a few BrdU-positive cells colabeled with GFAP (H-J). Intranasal administration of TGF-β1 increased the number of BrdU and NeuN-immunoreactive cells in the ipsilateral SVZ and striatum (D) at 28 days after stroke. Scale bars = 15 μm in A-C; 10 μm in E-J. Data are mean ± SEM. * P < 0.05 vs. control.
