In vertebrates, the ventricular zone is a transient embryonic layer of tissue containing neural stem cells, principally radial glial cells, of the central nervous system. The VZ is so named because it
The VZ and SVZ are indicated by immunohistochemical labelling of Sox2 and Tbr2 gene expression in the embryonic mouse forebrain at embryonic day 13.5. The dorsal telencephalon becomes the cerebral cortex, and contains the Tbr2-labeled cells. CP, cortical plate; LV, lateral ventricle; MGE, medial ganglionic eminence
