Figure Caption

Fig. 4 Proliferating neural cells express pCREB. Double-labelling immunofluorescence shows actively-proliferating cells in PZ2 are pCREB+. Coronal sections of adult zebrafish anterior telencephalon double-stained for PCNA (red) and pCREB (green) show most PCNA + cells lining the walls of the ventral diencephalic ventricles are pCREB+ (white box; x100 A and x400; B). Additional pCREB+ cells extending laterally into the telencephalon correspond to regions of migrating neuroblasts. Note differences in morphology between flattened, elongated pCREB+/PCNA + cells adjacent to the ventricular wall (white arrows) compared to smaller, round pCREB+/PCNA- cells (grey arrow) which have migrated tangentially into the telencephalon proper from the ventricular proliferation zone.
