Subventricular Zone (Svz) Neural Progenitors is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
The Subventricular Zone (SVZ) is the largest neurogenic niche in the adult mammalian brain, located along the lateral ventricles. It contains neural stem cells (NSCs) that continuously generate new [neurons](/entities/neurons) throughout life, particularly olfactory bulb interneurons.
Features: Intermediate progenitors that expand the stem cell pool
Neuroblasts (Type A)
Morphology: Elongated bipolar cells with leading process
Markers: DCX+, PSA-NCAM+, Tuj1+ (βIII-tubulin)
Features: Migrate via the rostral migratory stream (RMS) to the olfactory bulb
Normal Function
Adult Neurogenesis
The SVZ generates approximately 1,000-2,000 new neurons daily in the adult mouse brain, with estimates of 700 new neurons per day in humans. These new neurons integrate into existing circuits and participate in:
Olfactory Function: New olfactory bulb granule and periglomerular neurons replace older neurons and contribute to odor discrimination and memory
Age-Related Decline: SVZ neurogenesis declines with age
Reversibility: Exercise, environmental enrichment, and certain drugs can partially restore neurogenesis
