C Fraction of Nestin-, Tbr2-, DCX- and Calbindin-positive cells expressing β-Gal in BATGAL and Axin2LacZ/+ animals show stage specific canonical Wnt signaling during adult hippocampal neurogenesis [BATGAL: Tbr2 vs. DCX p=0.0056, DCX vs. Calbindin p<0.0001; Axin2LacZ: Nestin vs. Tbr2 p=0.0003, Tbr2 vs. DCX p=0.0115, DCX vs. Calbindin p<0.0001] (n= 3 animals per mouse model and marker).
