Triple-labeled M-phase cell near the emergence of the streams immunolabeled for glutamine synthetase (cyan), phosphohistone-H3 (green) and BrdU (red). The cleavage planes of niche cells are always oriented perpendicular to the track of the stream. Cytoplasmic labeling of the dividing cell for GS confirms that GS-labeled niche cells are the precursors of the neuronal lineage. Outlines of other niche cells also are GS-labeled. Asterisk marks vascular cavity. Scale bar 20 μm. [From Zhang et al., 2009]
