Fig. 4: Dendritic spine density is maintained in the hippocampus of old CTC KI/Cre mice.

a Representative micrographs of Golgi-cox staining and b quantification of dendritic spine density in hippocampal CA1 sections from 25-month-old CTC KI/Cre (n = 3), CTO KI/Cre (n = 5), CTC KI/WT (n = 4), CTO KI/WT (n = 4), WT/Cre (n = 5), and WT/WT (n = 4). WC: WT/Cre, WW: WT/WT. Data represent the mean ± SEM. One-way ANOVA followed by Bonferroni’s post-hoc.
