Age-related changes in doublecortin-expressing cells.

<p>Numbers of neuroblasts and immature neurons in each age group and genotype are listed for comparative purposes. Three comparisons are provided: 1) numbers of cells in 5–7 mo old NTG mice vs 13–15 mo old NTG mice; 2) numbers of cells in 5–7 mo old hAPP mice vs 13–15 mo old hAPP mice; and 3) the proportion of cells in 5–7 mo old hAPP mice relative to age-matched NTG mice vs the propotion of cells in 13–15 mo old hAPP mice relative to age-matched NTG mice.
