Chronic treatment with liraglutide increases cell proliferation in both wild type and APP/PS1 animals regardless of age. Quantification of Ki67 immunoreactive cells in the SGZ. Chronic treatment with liraglutide increases endogenous cell proliferation in both wild type and APP/PS1 animals regardless of age. ^*p<0.05, ^**p<0.01 compared with saline control. Values are expressed as mean ± SEM (n = 6).
