Ki-67⁺ cells in the medial temporal lobe from birth to adulthood. a Maps of the location of Ki-67⁺ cells (green dots) near the DCX⁺PSA-NCAM⁺ cell clusters in the PL (purple). Sections of the medial temporal lobe at 5 months, 6 years, and 24 years at anterior and posterior levels separated by 1 mm. (Right) Higher magnification showing location of Ki-67⁺ cells near the PL and temporal lobe lateral ventricle (tLV). b–d Ki-67⁺SOX2⁺ cells (arrows) and Ki-67⁺SOX2⁻ cells (arrowheads) near DCX⁺ cells in the MPL and LPL at birth (b), 5 months (c), and 6 and 24 years of age (d). e, f Quantifications of Ki-67⁺DAPI⁺ cells (e) and Ki-67⁺SOX2⁺ cells (f) in the MPL and LPL from birth to 24 years of age in the MPL, LPL, and BLA. Each point represents the average cell density (log-scaled) in each region within one individual at each age. Scale bars: 5 mm (a left), 1 mm (a right, b top right, c top right), 100 µm (b left, b middle left, b lower right, c left, c middle left, c lower right), 10 µm (b middle right, c middle right)
