Fig. 7 Long-lasting neuronal progenitors in the zebrafish adult telencephalic ventricular zone. Co-immunodetection of PCNA (green) and BrdU (red) after long-term tracing (19 days), observed under confocal microscopy on cross-sections (thickness indicated, dorsal up). Panels B–D are high magnifications of the areas boxed in panel A, panel D′ is a brightfield and fluorescence view of panel D to locate the ventricle (v). While most labeled cells have exited the ventricular zone, a few BrdU-positive cells are retained in cycle (yellow arrows); these cells are located throughout the DV extent of the telencephalic ventricular zone.
