E Representative images of recombined (GFP+, green) neurons in 24-week old animals at 13dpT 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. F Quantification of marker expression. The fraction of Calbindin expressing cells was increased in the recombined population in β-catex3 iDCX at 3dpT [p=0.0081] and 13dpT [p=0.0259] (3dpT: control: n= 4 animals, β-catex3 iDCX: n= 9 animals, 13dpT: control: n= 8 animals, β-catex3 iDCX: n= 10 animals).
