Neural stem cells in different locations of the postnatal mouse ventricular-subventricular zone (V-SVZ) generate different subtypes of olfactory bulb (OB) interneurons. High Sonic hedgehog (SHH) signaling in the ventral V-SVZ regulates the production of specific subtypes of neurons destined for the OB. Here we found a transient territory of high SHH signaling in the dorsal V-SVZ beneath the corpus...
The surgical management of Cushing’s disease is often complicated by difficulties detecting corticotropic adenomas. Various diagnostic modalities are used when conventional magnetic resonance imaging (MRI) is negative or inconclusive. We sought to analyze our use of two such modalities in the surgical management of Cushing’s disease: (1) cavernous/inferior petrosal sinus sampling (central venous sampling,...
Neural stem cells (NSCs) persist in the subventricular zone (SVZ) of the adult brain. Location within this germinal region determines the type of neuronal progeny NSCs generate, but the mechanism of adult NSC positional specification remains unknown. We show that sonic hedgehog (Shh) signaling, resulting in high gli1 levels, occurs in the ventral SVZ and is associated with the genesis of specific...
