B Representative images of recombined (GFP+, green) BrdU+ (grey) neurons in 24-week old control and β-catex3 iDCX animals at 13dpT expressing the stage specific markers DCX (red) for immature neurons and Calbindin (red) for mature neurons. Arrows and arrowheads indicate marker negative and marker positive cells, respectively. Scale bar= 10µm. C Quantification of DCX and Calbindin expression in BrdU+ recombined cells. At 13dpT, labeled neurons in β-catex3 iDCX animals show a shift towards a more mature marker profile [DCX p=0.0238, Calbindin p=0.0714] (3dpT: control: n= 4 animals, β-catex3 iDCX: n= 8 animals; 13dpT control: n= 5 animals, β-catex3 iDCX: n= 5 animals).
