<i>Bmal1</i>-KO exhibit enhanced survival of newly generated cells in the dentate gyrus relative to heterozygous and wildtype mice.

<p>A) Representative photomicrographs of BrdU (green) and NeuN (red) immunoreactivity in <i>Bmal1</i> (+/+), (+/−), and (−/−) mice 6 weeks after an i.p. injection of BrdU. Scale bar = 200 µm. B) High-magnification confocal image of NeuN/BrdU labeled cells. Scale bar = 10 µm. C) Total number of BrdU labelled cells throughout the hippocampus, calculated by counting cells in every fourth slice and multiplying by 4. *<i>p</i><0.05.
