Expression pattern of LKB1 in the adult dentate gyrus. Sample confocal images of hippocampal slices in adult Nestin-CreER/Rosa26-YFP mice that were double-stained with antibodies against GFAP/LKB1, MCM2/LKB1, DCX/LKB1, and NeuN/LKB1. White dotted circles, the nuclei of colabeled cells. Observation time: 1-mo postinjection. (Scale bar, 10 μm.)
