Intact rate of cell proliferation in the adult dentate gyrus of GluN2A^−/− mice.

<p><b><i>A, C,</i></b> Representative images of dentate gyrus sections processed for Ki-67 (<b><i>A</i></b>) and PCNA (<b><i>C</i></b>) immunohistochemistry in both wild-type (WT, <i>left panels</i>) and GluN2A^−/− (<i>right panels</i>) mice. (<b><i>B, D</i></b>) No change in the number of Ki-67-positive cells (<b><i>B</i></b>) or PCNA-positive cells (<b><i>D</i></b>) in the adult dentate gyrus of GluN2A^−/− mice in comparison to wild-type littermates. For both graphs, WT: black; GluN2A^−/−: white. Data is represented as means ± SEM. Scale bar = 100 µm (<b><i>A, C</i></b>).
