Characterization of GFP-positive cell types by immunohistochemistry.
GFP-positive cells included S100ß-positive ependymal cells lining at the lateral ventricular wall (a–c), GFAP or S100ß-positive astrocytic cells (d–i) and neuronal cells (j). (k,l) The proportion of each cell type in the GFP-positive cells in animals with SVZ injection (k) or lateral ventricle injection (l). The GFP-positive cells were classified as ependymal cells, astrocytic cells, neuronal cells and others based on their morphology and marker expression. Scale bars: 25 μm (a).
