Fig. 1.
A whole-mount mouse SGZ-derived neurosphere labeled with HA (red, using a biotinylated HA-binding protein), CD44 (green) and DAPI (blue; to stain cell nuclei). As shown here, some of the outermost cells in neurospheres, which are undifferentiated NSCs, express both CD44 and HA (yellow staining). The degree to which this co-localization occurs varies from one neurosphere to another.
