P.10 left column 3rd paragraph: "Interestingly, Smo-deleted adult brains appear to be of normal size, suggesting that Shh signaling is not a prominent requirement for the proliferation of neural precursors during development. Alternatively, it is possible that the observation of postnatal and adult neurogenic defects in Smo-deleted brain primarily relates to the longer duration of Smo-deficiency in the V-SVZ [Ventricular–Subventricular Zone] NSC [neural stem/precursor cells] population that is, perhaps the relatively rapid time course of mouse embryonic brain development (∼10 days) is too short to reveal a defect related to Smo-deletion." Smo=Smoothened, an oxysterol-binding protein required
