DA neurons are not a critical source of SHH ligand for SVZ NSCs
We observe no difference in the number of proliferating cells (A and B) or neuroblasts (C and D) in 3-month-old WT or DATcre-shh cKO mice at the SVZ, suggesting that DA neurons are not an active source of SHH ligand for SVZ NSCs. Mean + SEM.
(E and F) Quantification from multiple sections averaged in each animal. Each data point represents the average from an individual mouse. Mean + SEM. No significant difference between groups (Student’s t test). Scale bar = 100um.
