Immunohistochemical staining for tracing of BrdU-labeled cells; (A) the brown stain of the nuclei of BrdU+ cells are indicated by black and white arrows in cortex (scale bar 200 μm), a BrdU+ nucleus is shown by a higher magnification at the left upper corner (B) BrdU+ BMS cells in thalamus (white arrow) and dentate gyrus (Black arrow) (scale bar 500 μm) (C) BrdU-labeled BMS cells are observed in subiculum (black arrow), cortex (black arrow heads) and dentate gyrus (white arrow) (scale bar 2 mm)
