Two waves of horizontal basal cell (HBC)-derived neurogenesis. K5.CrePR1 tg/+: R26R+/− mice at various ages ranging from P10 to 12m were examined for the number of β-galactosidase (β-gal+) neuronal clusters in the olfactory epithelium per animal (clusters/animal), the cellular composition of individual clusters (cluster composition), and the total number of β-gal+ cells per animal (total cells/animal) (A). All numbers represent the average ± SEM of data obtained from five animals per age. In parentheses is shown the range of each data set. (B, C): Graphical presentations of (A), regarding cluster composition and total cells per animal, respectively. For simplicity, the data on SUSs are excluded. The first wave of HBC-derived neurogenesis started at P10, and the second wave peaked at 4m of age. Abbreviations: GBC, globose basal cell; m, months; ORN, olfactory receptor neuron; SUS, sustentacular cell.
