Ectopic, grafted cells in the needle tract. Representative microphotographs showing BrdU-labeled NSPCs grafted on P15 and evaluated 5 weeks after grafting. Cells were stained for BrdU (a, green), S100β (b, blue) and NeuN(c, red). Virtually all BrdU+ grafted cells in the needle tract (arrows) were positive for S100β (d). Scale bar=25 μm
