Confocal image of mouse dentate gyrus showing surviving cells (BrdU, red) that co-expressed markers of neuronal development (doublecortin, green; and calretinin, blue). Co-labeling of BrdU, doublecortin and calretinin identifies new neurons that survived following a chronic melatonin treatment. Scale bar 100 μm.
