Figure 5: BMSCs labeled by PKH26. A schematic drawing of a brain section 0.96 mm anterior to the bregma (a). Representative confocal micrographs of brain section obtained at anterior 0.98 mm to the bregma (b, c, and d). Merged images show BMSCs at the right primary motor cortex (c) and left external capsule (d). A bar in each microphotograph represents 50 μm (×400 in (c), (d)) and 2 mm in (b). A dotted rectangle indicates the contralateral extrernal capsule and a rectangular box indicates the right primary motor cortex.
