Histamine stimulates neurogenesis in the rodent subventricular zone.

Neural stem/progenitor cells present in the subventricular zone (SVZ) are a potential source of repairing cells after injury. Therefore, the identification of novel players that modulate neural stem cells differentiation can have a huge impact in stem cell-based therapies. Herein, we describe a unique role of histamine in inducing functional neuronal differentiation from cultured mouse SVZ stem/progenitor cells.

Neurogenesis in the adult mammalian brain occurs in two specific brain areas, the subventricular zone (SVZ) bordering the lateral ventricles and the subgranular zone (SGZ) of the hippocampus. Although these regions are prone to produce new neurons, cultured cells from these neurogenic niches tend to be mixed cultures, containing both neurons and glial cells. Several reports highlight the potential of the self-healing capacity of the brain following injury.
