Abstract: The existence of neural stem cells (NSC) in specific areas of the adult mammalian brain leads to the generation of new neurons involved in homeostatic mechanisms. This is the case of the NSC of the subventricular zone (SVZ) that produces olfactory bulb (OB) neurons. These neurons integrate into circuits to modulate sensory information and participate in olfactory processing (Bragado Alonso et al., 2019). A series of hierarchical events need to take place to produce OB neurons from NSC of the SVZ. First, the activation of quiescent NSC is necessary to produce intermediate transit amplifying progenitors (TAP), which will generate neuroblasts. The latter are cells that maintain a proliferative phenotype while in an immature phase. However, once they initiate migration toward the OB, they progressively undergo their differentiation into neurons (Kjell et al., 2020).
