F Representative images of recombined (GFP+) neurons co-expressing Prox1 (grey) as a marker for neuronal fate and 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. G Fraction of DCX expressing neurons is slightly reduced in β-catex3 iDCX at 3dpT [p=0.0338], while fraction of Calbindin expressing cells is slightly increased in β-catex3 iDCX at 3dpT [p=0.0345]. At 13dpT no difference is visible in stage specific marker expression [DCX p=0.8564, Calbindin p=0.0841] (3dpT: control: n= 12 animals, β-catex3 iDCX: n= 12 animals, 13dpT: control: n= 10 animals, β-catex3 iDCX: n= 14 animals).
