C Dendritic length [p<0.0001] and number of branch points [p<0.0001] was increased in 24-week-old β-catex3 iDCX compared to 24-week-old controls at 3dpT (control: n= 21 cells from 5 animals, β-catex3 iDCX: n= 20 cells from 6 animals). At 13dpT dendritic length [p=0.5788] and number of branch points [p=0.4978] were comparable (control: n= 21 cells from 5 animals, β-catex3 iDCX: n= 20 cells from 8 animals).
