Hippocampal histology in naïve mice lacking miR-22. Representative photomicrographs showing morphology of the hippocampus of wildtype (wt) and miR-22-deficient mice (miR-22+/−, miR-22−/−). Sections were stained with markers of a nissl, b NeuN (neurons), c GFAP (astrocytes), d Iba1 (microglia) and e parvalbumin (interneurons). No differences were found for any parameter (n = 6/group)
