Ki67+ proliferating cells (A,D) and DCX+ (B,E) or PSA-NCAM+ (C,F) young neurons in naked mole-rats (A–C) and highveld mole-rats (D–F). Note the staining of presumably myelinated fibers in (E arrow), which in some sections did not allow the identification of DCX+ cells in highveld mole-rats. Background in PSA-NCAM stained sections of naked mole-rats was considerably higher than in highveld mole-rats obscuring weakly stained cells. We therefore choose DCX for the quantitation of young neurons in naked mole-rats and PSA-NCAM for highveld mole-rats and Cape mole-rats (not shown). (A,E) are composites of two focal planes. Scalebars: 10 μm.
